A pre-workout supplement is almost standard for gym-goers these days.
It’s the best way to ensure you are energized and motivated for your next gym session, cardio workout, or competition event. They also help prepare your body for exercise with lots of vitamins and minerals.
Here are the best pre-workout supplements for peak workout performance and optimal post-workout recovery. Afterwards, we’ll dive into the details on how a pre-workout supplement can help you out.
1. Transparent Labs Pre-Workout
When it comes to pre-workout mixes, nothing is better than Transparent Labs. Why?
They offer 3 “custom” options of pre-workout—one for people who’re bulking (BULK), one for people who’re slimming down (LEAN), and one that is stimulant-free for all those people who freak out over stimulants (hey, I’m not mad at ya…).
All of this, and you still get a super “pump” with no artificial sweeteners, no artificial coloring, no artificial preservatives and 100% GMO-free.
They are also not stingy with the goods: BULK is stacked with 4,000 mg of beta-alanine and 4,000 mg of BCAA’s—a big reason why Transparent Labs has been one of the trendiest pre-workouts of 2020.
2. Blackwolf Pre-Workout
If you’re looking for a pre-workout supplement for men that will boost energy, enhance focus, and increase endurance during workouts… then you obviously need to be looking at Blackwolf Track Pre-Workout.
This all-in-one pre-workout supplement will increase not only your pump, but also the intensity of your workouts and your ability to focus on them.
The secret is Blackwolf’s specially formulated Blackwolf Power Blend, which is designed to help increase energy levels and really dial-in your ability to focus.
Key ingredients in this dynamic mix include vitamins B12 and B6, vitamin C, magnesium, potassium, pantothenic acid, zinc, selenium, thiamin, whey protein isolate, citrulline malate, and more.
It also contains some caffeine to top off the nice pump.
3. Ladder Pre Workout
Ladder provides a powerful pre workout supplement, packed with all the goodies. It stands out by providing a lower dose of caffeine, allowing you to enjoy your coffee as well – without worrying about caffeine overdose.
The inclusion of beta-alanine and creatine help push your muscles to the max, and beyond. With just a few grams of sugar, and a delicious flavor, it’s one of the top choices for the serious athlete.
4. 4 Gauge
4 Gauge delivers explosive power and laser-sharp focus — boosting both the mind and body —to help you achieve a better workout.
Their high-quality formula is backed by a considerable amount of research. Their are four key players in this formula that we want to highlight: caffeine anhydrous, l-theanine, creatine, and l-citrulline dl-malate.
The caffeine in this mix is well-dosed at 150 mg which, research suggests, should seriously improve physical performance. When combined with the l-theanine, it provides a powerful energy boost, but it does so with a smooth increase that’s proven to enhance mental focus. A strong serving of creatine brings the power in 4 Gauge, and an optimal dose of l-citrulline dl-malate is proven to boost endurance.
This supplement is completely natural, very generously dosed, and doesn’t contain any unnecessary fillers or proprietary blends. Overall, it’s simply a great supplement, and it’s no surprise that it’s popular.
5. Performance Lab SPORT Pre-Workout
Looking for a pre-workout that promises everything other pre-workouts do but without the stimulant crash?
Performance Lab Pre is the solution.
It contains scientifically backed ingredients that raise nitric oxide (NO) levels and maintain them throughout your workout and after, giving you a lasting pump and superior circulation.
Performance Lab Pre also contains antioxidants to help replace the electrolytes lost through sweating during intense exercise. An additional 1.25g of creatine replenishes ATP energy stores throughout your workout and boosts your strength and performance.
It also delivers 800mg of Carnosyn® beta-alanine that fights lactic acid build-up, the chemical responsible for muscle fatigue during your workouts, increasing your anaerobic capacity and reduce fatigue.
Importantly, it doesn’t contain caffeine so you’ll never be at risk from suffering jittery side effects. It’s a clean, vegan-friendly pre-workout that can still deliver improved performance.
6. BeetElite Sport
Before scientific research on the ergogenic properties of beets came out, it would have seemed laughable that a beet-based pre-workout supplement would become popular.
But it’s no joke now—BeetElite is one of the best-selling pre-workout supplements on Alpha XR, and centers its entire approach around using beet extract to improve performance.
Consuming large amounts of beets increases the availability of nitric oxide in your muscles, and this has been shown in scientific studies to have a profound effect on performance during aerobic exercise.
If an aerobic boost is what you need, BeetElite Sport is a great choice. Its primary ingredient is beetroot powder, along with a few natural flavoring and sweetening agents.
7. Legion Pulse
As the black label and serious, subdued style on the package would suggest, Legion Pulse is a pre-workout supplement for serious athletes.
The caffeine content—350 mg in two scoops—is likely enough to make some people look elsewhere. That’s as much caffeine as three and a half cups of coffee! Of course, you can always halve the dosage by using just one scoop.
Legion Pulse is one of the few pre-workout supplements to carry LabDoor’s “Tested for Sport” certification, meaning it’s been screened for the presence of substances prohibited by major sporting organizations, like steroids.
Aside from the active ingredient, Legion Pulse contains only a few anti-caking agents and natural non-caloric sweeteners.
8. Alpha GX7
Power and energy are the name of the game when it comes to Alpha GX7. All of the ingredients in this powder-based pre-workout supplement are geared towards boosting your energy levels and improving your peak power output.
In terms of stimulants, it’s got 250 mg of caffeine per scoop, more than just about any other competitor.
It also includes theobromine, a caffeine-like compound found in chocolate and cocoa, and taurine, which is a classic energy drink ingredient.
To round out the active ingredients, Alpha GX7 also includes Yohimbe, a West African herbal supplement that’s known to increase metabolism and virility.
9. Do Vitamins PumpPills
The pre-workout supplement offering from Do Vitamins stands out for a few major reasons.
First among these is that it is a pill, not a powder. It comes in a vegetarian cellulose capsule that contains a small blend of amino acids to help boost power production and get recovery rolling soon after your workout.
The main active ingredients are beta-alanine, which has anaerobic energy boosting properties, the amino acids L-citrulline and L-arginine, and L-malic acid. Aside from a few natural binders (rice extract and rice concentrate), there are no other ingredients, making this a great choice for simplistic-minded fitness enthusiasts.
Notably absent among the ingredients of Do Vitamins PumpPills are the kinds of stimulants found in other pre-workout supplements: there is no caffeine to get you jittery or sleepless, nor any risky stimulants like synephrine from bitter orange.
If you’re health-minded, or just don’t need any more caffeine in your daily life, this makes Do Vitamins PumpPills a great choice.
10. NO-Xplode 2.0
One of the few pre-workout supplements you’re likely to find out on retail shelves, NO-Xplode 2.0 comes with flashy advertising and a very long list of active ingredients.
The usual suspects are present: 225 mg of caffeine, a tremendous amount of B-vitamins, and moderate amounts of phosphorous, magnesium, and calcium.
The real attraction of NO-Xplode 2.0, however, is its proprietary workout blend. It contains dozens of ingredients, many of which are not seen in other supplements.
One downside is the decision to use sucralose and artificial colorings to flavor and color the powder—this might away some customers who are looking for naturally-sourced ingredients.
11. Cellucor C4 Extreme
As the best-selling pre-workout supplement on Alpha XR, Cellucor C4 is certainly popular. It’s a powder that includes a blend of B vitamins and vitamin C, alongside the workout-boosting supplements beta alanine, creatine nitrate, arginine AKG, and a proprietary “energy blend” that includes caffeine, several amino acids, and bitter orange, among other ingredients.
The caffeine dosage is fairly high—135 mg per scoop. This is around 50% more than what’s in a standard cup of coffee. For this reason, you should be a little careful with Cellucor C4 Extreme if you already consume other caffeine products during the day.
Who should buy a pre-workout supplement?
A pre-workout supplement is well-suited for people who are serious about the intensity and quality of their training sessions. If all you do is hit the gym to stay in decent shape, a pre-workout supplement probably isn’t necessary.
On the other hand, if you want to improve your personal bests or achieve the highest level performance possible, a pre-workout supplement can help you take things to the next level.
Pre-workout supplements include ergogenic compounds like caffeine, beta-alanine, and L-carnitine, all of which can increase your performance on lifts, intense anaerobic circuits, and endurance events alike.
The combined action of these supplements can boost your workout performance in the short term, as well as build up your body’s capacity for high-level performance in the long term. Compounds like caffeine or guarana can boost your performance short-term (i.e. today), while supplements like creatine and beta-alanine accumulate in your system, increasing your ability to perform in workouts over the course of weeks and months.
Since pre-workout supplements combine both of these types of performance enhancers, they’re the optimal tool for perennial high-level performance.
Best pre-workout overall: Transparent Labs Pre-Workout BULK and LEAN
Whether you’re lifting for strength and size or hitting the gym to shed some pounds, Transparent Labs has you covered. The BULK formulation is packed with amino acids for rapid muscle growth, and the LEAN formulation is designed for optimal fat oxidation.
Best pre-workout for lifting: Blackwolf Pre-Workout
For maximum gains, choose Blackwolf—its combo of whey protein isolate, creatine, and branched chain amino acids is unbeatable when it comes to supercharging your muscular supercompensation after tough lifting workouts.
Best pre-workout for cardio: Ladder Pre-Workout
Ladder gets the mix for cardio just right: a moderate amount of caffeine, plus beta-alanine for high-intensity cardio output. On top of that, you get just enough sugar to increase endurance performance without getting stomach cramping even during hard running, cycling, or rowing.
Best pre-workout without caffeine: Performance Lab SPORT Pre-Workout
Looking to ditch caffeine jitters? Performance Lab has you covered. Their SPORT Pre-Workout uses glutathione, beta-alanine, and pine bark extract to sustain high-energy output from your muscles without the need for caffeine.
Best pre-workout for bodybuilders: Transparent Labs Pre-Workout BULK
BULK provides all the essentials for bodybuilders working to maximize muscle size and definition: zinc for optimal testosterone, betaine and beta-alanine for sustaining high-rep lifts, and a wide range of amino acids (including BCAAs) for optimal muscle recovery.
Best pre-workout for women: Ladder Pre-Workout
Ladder is perfect for women thanks to its simple, clean, and effective formulation. Unlike many of its competitors, it’s not bloated with excess sugar or way too much caffeine, yet it still provides creatine and citicoline for extra strength, power, and energy.
How we ranked
We took a holistic approach to pre-workout supplements, keeping in mind the multi-purpose nature of the range of compounds included in pre-workout formulations.
For each of the pre-workout products on the market, we analyzed the ingredients to identify the biologically active ingredients, then classified each of these ingredients as a short-term ergogenic (like caffeine) or a long-term ergogenic (like L-carnitine).
To make our rankings, a pre-workout supplement had to include at least one potentially ergogenic compound from each category.
We also evaluated supplements on the presence of other, more cutting-edge performance enhancers like yohimbe, but put less stock in these emerging ingredients, because the scientific evidence to support them is not as strong as the core stack of performance enhancers we were looking for.
When it came to the short-term ergogenic aids, we took a very close look at caffeine content. While caffeine is a very powerful ergogenic aid in moderation, far too many pre-workout supplements on the market are nothing more than overpriced heavily-caffeinated sports drinks.
We tossed out products that leaned too heavily on caffeine content, and made sure to include some pre-workout formulations that were totally stimulant-free. If you have to hit the gym at night, a pre-workout that’s heavily caffeinated could be a huge disaster when it comes to maintaining a healthy sleep schedule.
To analyze the dosage, transparency was critically important to us. We strongly penalized formulations that hid the specific amount of each ingredient in the supplement behind a “proprietary formula,” as these types of tricks make it impossible to fully evaluate the efficacy of a supplement.
Several big-name pre-workout supplements from major supplement companies, like Six Star Explosion Pre-Workout, failed to make the rankings for this reason.
Our final rankings, sorted by overall quality and efficacy, represent the best products on the market according to these criteria—they balance out short-term performance, long-term improvement, and all-around efficacy.
A pre-workout can include a lot of different ingredients all at once. Pre-workout supplements are a broad category that includes fairly simple blends of amino acids which increase protein availability to your muscles before and after a workout, to more advanced blends of stimulants, herbal extracts, and energy-boosting products that are designed to solicit the best possible effort from your body during a workout.
Obviously, these supplements are going to be geared towards people who work out seriously; many pre-workout supplements specifically target power sport athletes, like weight lifters.
Since pre-workout supplements include such a broad range of products, it’s more informative to look at what some of the most common ingredients can do for you
Caffeine can improve many different types of performance. Present in nearly every pre-workout supplement, caffeine is a powerful and well-known ergogenic aid. According to a review by the International Society of Sports Nutrition published in 2010, caffeine is a highly effective performance enhancer when it comes to a number of different physical tasks (5).
Caffeine boosts everything from sustained endurance exercise (running a race, doing a cycling time trial, working on the rowing ergometer) to tasks demanding intense coordination and starting and stopping (pickup basketball, ultimate Frisbee).
There is also some evidence that it helps with maximal strength exercise, like lifting weights, but more research is needed on that front, according to Erica R. Goldstein and the other authors of the position stand.
L-Carnitine can increase anaerobic power and strength. An amino acid that’s often found in pre-workout supplements, L-Carnitine is included principally to boost the hormonal response to resistance exercise (i.e. lifting weights).
A study published in 2006 by William J. Kraemer and other researchers at the University of Connecticut studied how taking a supplement containing L-Carnitine after a strength workout affected recovery (6).
The researchers followed ten weight lifters who consumed an L-Carnitine supplement over the course of three weeks, all while monitoring their blood markers of muscle growth.
The researchers found that the L-Carnitine supplement increased the activity of something called the androgen receptor response. This meant that the lifters’ bodies were more attuned to the muscle-building effects of androgen hormones like testosterone.
This could mean bigger gains from your lifting program. The researchers also noted that this androgen receptor response was better if you consumed a meal containing carbohydrates, fat, and protein soon after finishing the workout.
Beta-Alanine boosts anaerobic power as well. An energy supplement that boosts your muscles’ ability to produce power anaerobically, beta-alanine is proving to be an increasingly popular ingredient in pre-workout supplements.
Regular intake of beta-alanine has been shown to increase your muscular content of a compound called carnosine, which helps increase your tolerance for the buildup of acidity in your muscles.
Carnosine acts as a buffering agent, delaying the onset of the “burn” during high-intensity exercise that causes fatigue. According to a scientific paper by Guilherme Giannini Artiolo and other researchers at the University of Sao Paulo in Brazil, beta-alanine acts directly to increase muscular carnosine concentrations and directly improves performance in activities that are limited by intramuscular acidity.
Two categories of exercise that fall under this classification are intense intermittent exercise (like a high intensity interval training protocol) and continuous high intensity exercise lasting over sixty seconds, like longer sets of weight lifting or strongman exercises (e.g. stone carry).
Because short sets of lifting are not limited by intramuscular pH, they won’t be affected by a beta-alanine supplement, so make sure you know what your workout will entail before counting on beta-alanine to make a difference.
Creatine increases muscle mass and strength. Some pre-workout supplements, though not all, contain creatine, either in the nitrate or monohydrate forms. Creatine is a widely-known performance boosting supplement; it increases muscular strength, enables higher quality workouts, and directly increases the concentration of phosphocreatine inside your muscles.
Phosphocreatine is a major power source for fast, maximal muscle movements, like doing a set of squats or bench press. Among pre-workout supplements, creatine is likely the most effective when it comes to direct improvements in your lifting ability.
According to a 1999 study by Jeff S. Volek and colleagues at the Pennsylvania State University, supplementing with creatine can increase muscular creatine content by over 20%, and total body mass and lean body mass increases can be expected while taking a creatine supplement as well (8).
Muscular cross-sectional area and raw strength, as measured by bench press and squat, can be expected to increase by 25 to 30%.
Creatine is a powerful workout-boosting compound, and if your pre-workout supplement doesn’t have it, you should probably add a dedicated creatine supplement to your routine, assuming your goals are to increase muscular size and strength.
More advanced pre-workout ingredients such as yohimbe could help cut body fat. While the traditional ingredients in a pre-workout supplement, like caffeine, beta-alanine, and L-carnitine, are great for improving performance, many manufacturers are looking to push the limits with new, cutting-edge ingredients.
One such compound that hold some promise on this front is yohimbe, but not because it improves performance directly. Instead, yohimbe might be able to decrease body fat content in high-level athletes during periods of intense training. That was the conclusion of a study published in 2006 in the journal Research in Sports Medicine (9).
The paper used a yohimbe supplement in a small group of soccer players over the course of 21 days. While the soccer players taking the yohimbe supplement did not improve their athletic performance on standardized tests compared to the placebo group, the yohimbe group did experience a significant drop in body fat percentage.
The author of this study concluded that yohimbe could be a useful way to drop body fat, even while continuing an intense training program. For that reason, you’ll find yohimbe in some of the more advanced pre-workout formulations.
BCAAs in a pre-workout can help prevent soreness. Not every ingredient in a pre-workout needs to be intended to improve performance. Sometimes, it’s better to prevent some of the negative effects of very challenging workout sessions, like delayed onset muscle soreness.
Workouts that involve a lot of eccentric muscular contractions, like squats, deadlifts, and running hills, create a substantial amount of muscular damage, and research suggests that a pre-workout that contain branched-chain amino acids (aka BCAAs) can reduce some of this damage. A study published in 2010 in the journal Medicine and Science in Sport and Exercise tested the effect of a BCAA supplement on muscle soreness in 24 men (10).
Using a placebo-controlled study, the researchers tested to see whether BCAAs would reduce the amount of soreness experienced after a series of extremely fatiguing eccentric knee exercises.
The researchers found that the BCAA supplement group experienced lower feelings of soreness following the protocol, which suggests that a pre-workout supplement that includes BCAAs could be well-suited if you are doing eccentric-dominated exercises that you know are going to leave you feeling sore.
As you might guess, the side effects of a pre-workout supplement are going to depend a lot on what’s in it.
Caffeine is one nearly ubiquitous pre-workout supplement ingredient that has a well-characterized side effect profile: caffeine can cause nausea, jitters, and sleeplessness, and when taken in too high of a dose, it can cause heart arrhythmias, seizures, and other serious medical problems. This will become more of a concern if your pre-workout supplement contains a lot of caffeine per serving.
A few pre-workout supplements contain bitter orange or its active ingredient, synephrine. This ingredient has caused some doctors to issue warnings that it has a side effect and biological profile similar to that of the banned stimulant ephedra; indeed, many weight loss supplements that used to contain ephedra now switched to using synephrine after the FDA banned ephedra.
If you’re concerned about the potential cardiovascular side effects of synephrine, avoid supplements that contain it—especially when they also contain caffeine (11).
Beta-alanine has some side effects too, but they are much milder.
When taken in doses above about 800 mg, it can cause paresthesia—a tingling or prickling sensation, especially in your fingertips, ears, or feet.
This appears to be the result of peak levels of beta-alanine in the blood, so all you need to do to avoid this in the future is split up your pre-workout supplement into smaller doses taken at thirty or sixty minute intervals.
Because the ingredients of different pre-workout supplements vary so much, you tend to rely on the supplement manufacturers to do most of the work when it comes to determining optimal dosages. Nevertheless, some of the key ingredients can be analyzed for optimal dosing.
Caffeine achieves its best effects when consumed in amounts of 3 to 6 mg per kilogram of body weight—so a 170 pound man (77 kg) would consume 230 mg of caffeine to get a dose of 3 mg/kg.
Doses above 6 or 9 mg/kg don’t appear to be any more effective, and they have a higher incidence of negative side effects. Creatine is recommended in amounts of up to 25 g per day, so you may need a separate creatine supplement to hit this amount. Beta-alanine is usually recommended in doses of 1000-1500 mg per day.
Q: What is a pre-workout?
A: A pre-workout is a combined supplement that is designed to provide ingredients to increase your athletic performance in your workouts.
These supplements are designed to boost both short-term performance (i.e. your workout performance today) plus your longer-term athletic ability (i.e. your workout quality a few weeks from now).
This effect is achieved using a balance of supplements oriented towards both short and long term performance enhancement.
Often, but now always, pre-workout supplements are powder-form products that you can mix with water and drink right before you work out. As such, they also have to be engineered to taste good.
Q: What are some good natural pre-workouts?
A: If you are looking for natural foods and natural compounds to take as a pre-workout, things derived from real foods are a great place to start. BCAAs, coffee, and green tea extract are all effective and all-natural compounds you can take before you work out to increase your performance.
Some of the more specialized compounds, like beta-alanine, can’t be derived in significant amounts from a natural source: they need to be refined or synthesized in a lab. So, while natural compounds do offer a lot in the way of pre-workout benefits, top results do tend to require the refined compounds you find in commercial pre-workouts.
Q: Is pre-workout safe?
A: The safety of a pre-workout is going to depend on the specific ingredients. The biggest potentially problematic pre-workout ingredients from a safety perspective are stimulants, which can range from garden-variety things like caffeine to more potent and also potentially more dangerous compounds like synephrine or bitter orange peel.
Caffeine is safe when you keep the dosage under control (it is, after all, the most-used physiologically active drug in the world), but things like synephrine can be riskier.
We recommend sticking to pre-workout supplements that are either stimulant-free or whose only stimulant is caffeine in moderate amounts. These are the kind of products you’ll see on our rankings.
Q: Are pre-workout supplements necessary?
A: “Necessary” depends on your interpretation. If you just want to get a solid effort in at the gym, and aren’t looking to smash any records or push yourself up to your body’s physiological limit, a pre-workout is not going to be necessary to achieve your workout goals.
If, on the other hand, you are looking to max out a lift, or push yourself harder than ever in a HIIT session, a pre-workout supplement might be just what you need. Pre-workouts can also be useful when you are not feeling up for high-level performance, but still need to work out.
Prime example? Early-morning gym sessions. If you are sleep-deprived but need to kick your body into high gear, a pre-workout supplement is one surefire way to do it.
Q: What does a pre-workout supplement do?
A: Pre-workout supplements work by activating multiple biological pathways in your body at once, all of which are connected to performance.
So, for example, caffeine disinhibits your central nervous system, allowing you to perform better and push yourself harder at high intensities.
Fat burners like green tea extract increase your body’s rate of fat oxidation, which can increase endurance performance, while ingredients like L-carnitine and beta-alanine boost the ability of your muscles to sustain high-intensity anaerobic efforts.
Other ingredients, like BCAAs, may not directly boost performance, but can protect your body from soreness induced by your workout.
Q: What’s the difference between a pre-workout and post-workout supplement?
A: Pre- and post-workout supplements may share a few ingredients, but as their names suggest, there are stark differences in their intent.
A post-workout supplement is oriented around recovery. After you finish your workout, you need to supply your body with the nutrients it needs to rebuild muscle and replenish its energy stores. In contrast, before you work out, you want supplements that will prime your body for peak performance.
These are not often the same things. While there is a little crossover, such as with BCAAs, typically you’ll find that the ingredient profile in a pre versus a post workout are markedly different. You’re not likely to find caffeine, for example, in a post-workout supplement.
Q: How long does pre-workout last?
A: Most pre-workouts are engineered to last for around two to three hours, but getting more specific than this is tricky, because different ingredients operate on different timescales.
Caffeine, for example, has a fairly well-defined window of efficacy: you want to take it at least 45 minutes prior to working out, and once having taken it, the effects will last for up to five hours. Other ingredients, though, like BCAAs, are absorbed more quickly, and ideally you’d like your workout to be over before the BCAAs have been processed by your body.
Fortunately, reputable companies will take these variations into account when formulating their pre-workouts, so you can count on a pre-workout to exhibit its effects for somewhere in the neighborhood of two to three hours with pretty good reliability.
Q: Why does pre-workout make you tingle?
A: Tingling after taking a pre-workout supplement means one of two things: either the pre-workout supplement that you are taking has a lot of beta-alanine, or a lot of niacin (also known as vitamin B3).
Both of these ingredients cause flushing and tingling at high doses, and while this side effect is unpleasant, it isn’t harmful.
Check the label of your pre-workout to find out which of these two is the culprit. If it’s beta-alanine, you can usually eliminate tingling by limiting the beta-alanine dosage to 800 mg or less at once (you can take more beta-alanine at different times during the day if you are trying to load up your intramuscular carnitine).
If it’s vitamin B3 that is causing tingling, you want to limit the dosage to less than 30 mg of nicotinic acid per day.
Q: How can you spot a fake pre-workout?
A: Low-quality pre-workout supplements are characterized by the presence of a lot of sugar, a lot of caffeine, and very little in the way of other effective supplements.
Watch out for products that hide all of their ingredients in a “proprietary blend,” as this allows the manufacturer to obscure the fact that the amount of the active ingredients could be far below what’s necessary for optimal performance.
Like with many knock-off weight loss pills, heavy reliance on caffeine is a common shortcut to giving the impression that a pre-workout is accomplishing more than it really is.
Choosing a reputable manufacturer, like those in our top rankings, is a good way to ensure you’re actually getting a beneficial pre-workout.
Choosing the best pre-workout supplement is a matter of investigating the effects of the active ingredients, then comparing them to your own workout goals.
Doing a lot of heavy lifting will mandate a different pre-workout supplement than doing a lot of cardio or high intensity interval work, so do your homework before buying.
