Out of all supplements on sale, pre-workouts are some of the most popular ones available. When taken before a gym workout or a long run in nature, pre-workouts work to enhance your mental and physical capacities – giving you a burst of motivation.
Needless to say, finding the right pre-workout for you can be a tricky task. Many contain a wide array of ingredients and doses, all with their own unique effects and properties to completely shift your performance and mental state.
While your nutrition, sleep, and hydration are all key to maximizing your workout potential, sometimes you’ll need an extra push. A pre-workout can make a huge difference here. Choosing the right pre-workout will help you get the absolute most from your training and aid your efforts to see your goals through.
In such a crowded market and with so many supplements claiming to be the best, how you do tell what is legit and what is not?
We’re jumping in to help. We’ve scoured the pre-workout market with a fine-tooth combo, looking at the biggest brands (and also fresh up-and-comers) to find the top pre-workouts you can get in 2021.
What are Pre-Workout Supplements?
Pre-Workouts are food supplements normally taken before exercise to enhance energy and performance.
Usually available in powder form – and less often in capsules – you mix them with water and chug down 15-30 minutes before exercising.
A good, natural pre-workout will stimulate your body’s energy levels, using ingredients like caffeine and beta-alanine to nudge you in the right direction whenever you’re fatigued or sluggish.
Essentially, a pre-workout will provide you with a short-term power, endurance, strength, and energy burst to help you smash your workouts.
Why a pre-workout?
Athletes, bodybuilders, and regular gym goers all over the world take pre-workout supplements before hitting the gym or going for a run. Pre-workouts give you an extra push to go harder for longer where otherwise you’d be too fatigued to continue working out, or even get started.
Taking a pre-workout though is a very individual thing. For some people, they wouldn’t be able to motivate themselves to hit the gym without a pre-workout supplement. Others may use it to help them get a few extra reps to break their months-long plateaus in the gym.
These common, stimulating food products work as a key link to boost your drive and enthusiasm to exercise.
A pre-workout will work wonders for anyone who:
- Needs an energy kick to maintain their fitness routine
- Wants to increase muscle pumps from resistance training
- Has a hard time finding the motivation to exercise
- Wants to maximize muscle growth potential and increase their Rep Count
- Is looking for a natural, and legal way to put their physical and mental performance into high gear
Most Effective pre-workout ingredients
Here are some of the most effective and thorougly researched ingredients to look for in pre-workout supplements.
A staple ingredient in most pre-workouts, L-Citrulline works by boosting blood flow to your working muscles – resulting in increased performance. This ‘vasodilator’ amino acid is best known for delivering fuller muscle pumps, courtesy of elevated Nitric Oxide (NO) blood levels. Studies show that improved muscle pumps lead to amplified muscle growth. [source1] Although it’s available in small amounts in watermelons, L-Citrulline’s therapeutic effects are very hard to achieve with food alone.
A well-known stimulant in fat burners and pre-workouts, caffeine is the most effective legal enhancer of physical and mental faculties. Caffeine stimulates the parts of your brain and nervous system to boost functions like motivation, focus, and alertness – making it a potent pre-workout ingredient. Not only that, but caffeine also boosts workout volume and your power output, as well as enhancing energy through the release of extra epinephrine. [source2]
Beta-alanine: this fatigue-fighting molecule shines the brightest during intense workouts, by helping you to maintain peak performance. If you’ve ever felt the ‘burning’ sensation in your muscles while doing high repetitions, you’re aware of the fatiguing effects of acid build-up, which can prevent you from making progress. Beta-alanine works by blocking this build-up, and consequently, letting you do more reps, resulting in more significant muscle growth. [source3]
One of the most researched supplements taken by almost all athletes, creatine will boost your performance by expanding your natural energy stores (ATP) and efficiently raising power output of your muscles. [source4] Creatine is the fastest natural way to regenerate your ATP stores. Since your body only holds a small amount, you’ll need to supplement creatine to avoid depletion during exercise.
L-Theanine is a dietary amino acid that increases mental focus and cancels the jittery effects of caffeine – in fact, the two are shown to work incredibly well together. While L-Theanine keeps you in a mediative-like state, caffeine boosts your energy to exercise harder for longer. Together, caffeine+l-theanine will deliver clean energy and motivation without the crash. [source5]
Advantages to a pre-workout
If you’re lacking consistency, it will be hard to make any concrete progress. A good pre-workout will ensure you have more zest for going to the gym, and it will also increase your energy once you’re there lifting those weights.
Benefits of taking a pre-workout supplement include:
- Better physical performance – The combination of natural ingredients like citrulline, caffeine and beta-alanine will invigorate your workouts, allowing you to push harder and really challenge your body.
- Boosted blood flow – Feel stronger and experience shirt-ripping muscle pumps.
- Better muscular endurance – By supplementing with creatine you’re effectively feeding your body with a more consistent source of energy in your mitochondrial cells.
- Improved muscle recovery and growth – The vasodilators and other ingredients in pre-workouts will increase nutrient delivery to your working muscles, improving growth and recovery in the process.
