A lot of fitness talk is focused on pre-workout supplements. As a beginner looking for that extra boost, all those many options can be daunting. The main aim for your pre-workout may not be to bulk up your muscles but to keep you sharp and promote your hydration.
If you are considering a pre-workout, you have probably heard reports of tingling or even itching that can be worrying.
You expect you can push harder yet you really do not want such distractions before you exercise. A raised sense of anxiety that can really put you off your workout.
The included supplements should leave you sharp and focused on achieving your best. With so many on offer, knowing the contents and their own objectives should give you a better idea of which pre-workouts can boost your performance.

Best For Bulking
Transparent Labs PreSeries BULK
Greater Energy and Endurance with BCAA: Valine is essential in pre-workout supplementation due to its involvement in metabolism and muscle growth. It helps to reduce tryptophan build-up in the brain and allows for greater energy and endurance. Leucine is a strong activation of the gene responsible for protein synthesis which significantly increases strength and prevents muscle degradation while preserving lean mass. Isoleucine aids metabolism during workouts and executes anti-catabolism effects.
Citrulline malate is the “star child” of pre-workout science. We chose citrulline malate over L-arginine because it provides better absorption, higher plasma arginine levels, and has been found to: Improve strength, aerobic performance, and muscle endurance. Be at least twice as effective as L-arginine supplementation at raising nitric oxide. Enhance the use of branch chain amino acids like leucine during exercise.
Muscle Growth and Decrease Cortisol: Clinical studies suggest that betaine supplementation triggers a significant muscle growth response. This response is independent of testosterone. Betaine supplementation has also been shown to: Reduce fatigue when taken before and during weight training. Increases total repetitions and volume on the bench press exercise versus placebo. In a recent study, betaine was found to significantly increase IGF-1, while decreasing cortisol in bodybuilding men.
Delay Fatigue and increased cellular carnosine levels: Beta-Alanine increases cellular carnosine levels, which are quickly depleted during intense exercise. Most pre-workout supplements contain beta-alanine but at significantly underdosed levels. Proper dosing of STIM-FREE delays the onset of neuromuscular fatigue in men and women during intense exercise and Promotes the formation of healthy proteins Significantly increase lean mass and decrease fat in wrestlers.
Long-Lasting Mental Focus and Performance: Infinergy prolongs the ergogenic effects of caffeine and provides a longer-lasting increase in mental performance and thermogenesis without the jitters and crashing from ordinary caffeine. L-tyrosine reduces the effects of stress and allows for greater mental focus and endurance. L-tyrosine improves memory and performance in bodily stressing climates, and it is believed to counteract the hypothyroid promoting conditions associated with extensive exercise.
Some pre-workouts do exactly what they say on the tub and Transparent Labs are known for their transparent labels. With a specially designed formula, Transparent Labs PreSeries BULK is great for bulking up muscle mass which we liked in our testing.
Key ingredients include leucine for protein synthesis and to maintain lean muscle mass. Betaine is also on the list of ingredients due to its muscle growth response, you should also feel less tired when weight training.
In total, nineteen active ingredients are in every scoop for the production of nitric oxide, known for increased blood flow and to increase the ‘pump’.

Buyers’ Guide
Just finding a brand you feel you can trust may be difficult enough if you are a beginner trying to find their pre-workout.
They all seem to claim that their formula is the one for muscle gain, endurance, strength, or all three.
While you may not have aspirations to compete in any bodybuilding competitions, you could simply want a pre-workout that helps you focus just when you need to.
Caffeine Content
Your pre-workout should give you a boost, otherwise you would fail to know it is working as expected.
A lot of that energy boost comes from the caffeine content. If you are someone that enjoys a coffee (or five) then you may want to consider how much caffeine is contained in each scoop.
Some formulas will only contain around 100mg per scoop whereas others will go as far as 400mg. That may be deemed excessive, it is certainly not ideal if you want to curb your caffeine intake.
If you struggle to sleep most nights, having a huge dose of caffeine before a late-night workout or run could really make matters worse. You could also suffer the dreaded caffeine crash a few hours later.
Caffeine Alternatives
Including an alternative to caffeine is crucial in your pre-workout if you have an intolerance or a heart condition. Put simply, there is no direct alternative that will replicate the effects of caffeine but there are potential solutions.
However, in any case, if you have a heart condition then you should steer clear of all stimulants, not just caffeine. Should you be able to handle a minimal dose of caffeine then combining it with theanine could effectively improve your performance and focus.
Aside from caffeine, there are specific ingredients that you should ensure are on the label of your pre-workout. One is beta-alanine which can boost your endurance to help you go that bit further for longer without crashing.
The substance should also aid your muscle recovery so if it is not included in the formula you could always buy it separately.
Creatine is also important for enhancing your strength and power. This is one of the most crucial ingredients for a pre-workout as it not only supplements your muscle-building but your recovery, hydration, and even your cell health.
If you keep seeing pre-workouts that mention the ‘pump’, chances are the formula includes citrulline.
The substance has been valuable to bodybuilders for increased blood flow to increase muscle mass. Citrulline can also improve your post-workout recovery and 3g is a good amount to seek out.
Vitamins And Minerals
For general wellbeing, you should consider the vitamins and minerals included in your pre-workout.
They also help your performance and alertness before your run or gym session. There will also be certain pre-workouts that go above and beyond providing you with your daily doses, some will even provide as much as 600%
Frequently Asked Questions
Why Should I Take A Pre-Workout As A Beginner?
If you are wondering why you are yet to take the step-up to a certain PB in running or at the gym then you should take a pre-workout. While you may imagine that taking supplements is just for gym-obsessives and bodybuilders, they can give you that push you need.
Pre-workouts can enhance your endurance, energy, mental focus, and muscle gain. That is not just for advanced fitness levels but beginners too.
A lot of manufacturers have included directions on how to mix your pre-workout and when to consume it. As a general rule to feel the best results, you should take your pre-workout about half an hour to an hour before your run or gym workout.
That should be ample time for the pre-workout to hit your bloodstream and provide that energy boost.
However, simply because it is called ‘pre’-workout does not necessarily mean you need to take it before your session. If you want a quick boost during a long session, take it an hour in, or at the halfway stage, of your session.
