What is a pre-workout?

Pre-workouts are performance-enhancing supplements normally taken before exercise to provide a boost of motivation and energy. Usually available in powder form, you mix them with water and drink the formula at least 15-30 minutes before training.

Although we always recommend eating a great range of nutrient-rich foods to keep your physical and mental performance at its peak, pre-workouts work to give you a nudge in the right direction whenever you’re feeling sluggish or fatigued. Essentially, they provide a short-term energy, power, endurance and strength burst to help you dominate your workouts.

Why take a pre-workout?

You’d normally take a pre-workout before hitting the gym or setting off on a run. In fact, they are commonly taken by a range of athletes, bodybuilders and gym users to get that extra ‘push’.

Taking a pre-workout though could be very individual and everyone has different reasons. For some users, they wouldn’t be able to get to the gym without a pre-workout. These common, stimulating supplements work as a missing link to help boost enthusiasm and drive to exercise.

A pre-workout would work wonders for anyone who:

  • Needs an energy lift to stick to their fitness goals
  • Is looking to heighten muscle pumps from strength training
  • Works long hours and finds it hard to exercise
  • Wants to increase their rep count and maximize muscle growth
  • Wants a legal, and natural way to improve their physical and mental performance

Best pre-workout ingredients

These are some of the best and rigorously researched ingredients to look out for in pre-workouts.


A staple found in most pre-workout formulas, L-citrulline works to improve blood flow for better workout performance. Also known as a vasodilator, the amino acid raises levels of nitric oxide in your body, which can improve blood flow and boost muscle pumps [source 1]. Studies show that increased muscle pumps may amplify muscle growth [source 2]. L-citrulline is found naturally in some foods like watermelon but optimal amounts can’t be consumed from food alone.

Caffeine Anhydrous

A popular stimulant found in fat burners and pre-workouts, caffeine is incredibly potent in enhancing mental and physical performance. Caffeine activates parts of the brain and nervous system to boost feelings of alertness, focus and motivation, making it a powerful pre-workout ingredient[source 3 and 4]. Not only this, but caffeine may also increase power output and your workout volume[source 5], as well as enhancing performance by releasing more of the hormone epinephrine (adrenaline) [source 6].


This fatigue-fighting compound works to keep your muscles performing during the most intense workouts. If you’ve ever felt the burn on your final set, you’ll understand the fatiguing effects of acid buildup and how it can hold you back from making progress. Beta-alanine works to block this buildup and improve muscular endurance. Beta-alanine helps your body make carnosine, a molecule which reduces acid levels in muscles during exercise, lessening overall fatigue [source 7]. This can push you to train for longer periods at higher intensity.

Lean and fit woman drinking the best pre workout supplement


A rigorously tested supplement taken by practically every athlete, creatine works to boost exercise performance by increasing your natural energy reserves (ATP) and delivering energy to your muscles [source 8]. Creatine is commonly used in pre-workouts as it’s the quickest natural way to regenerate your ATP stores. Because your body only stores a small amount, you need to supplement creatine. Creatine has been shown to boost power output as well as lean mass too.


L-theanine works well with caffeine to promote increased levels of mental alertness, without the annoying jitters. By introducing more calmness to your brain activity, you can stay focused on the task in hand – an intense workout. The smart-caffeine combination may boost cognitive performance and amplify alertness, helping you stay motivated during exercise [source 9].

Advantages to using a pre-workout

Pre-workouts work to support your normal nutrition to deliver increased energy and concentration for your training sessions. Benefits of taking a pre-workout include:

  • Increased physical performance – The role of many pre-workouts is to raise your energy levels and focus. By combining a range of natural compounds like creatine, caffeine and beta-alanine, a pre-workout can enhance mental preparedness, deliver power to your muscles and help you feel more motivated to hit the gym.
  • Boosted blood flow – Pre-workouts contain compounds that boost levels of nitric oxide, which is used by your body to improve blood flow. This can deliver more oxygen to your working muscles, improving your pump and increasing your workout intensity.
  • Better muscular endurance – Creatine is a naturally occurring substance that’s stored in muscle and provides your body with energy. By supplementing with a pre-workout containing creatine, your muscles can access more energy and will perform better.
  • Improved muscle recovery and growth – Some pre-workouts contain vasodilators and other ingredients that can help increase blood flow to muscle tissue, improving recovery and growth. If you can push harder too, you’ll be able to increase your rep count and really challenge your body.
