What Is Pre Workout?

So you know that pre workout can supercharge your training, but what is it, and why does it work? 

It would be impossible to turn up the gym 100% of the time and feel on top of your game. You might feel lethargic, tired, and unmotivated. This could be from a hectic life, stress at work, or seasonal feelings. A pre workout is a supplement aimed at leveling the ground. 

By using a pre workout, you significantly increase your body’s VO2 max and training volume. This then equates to gains in lean body mass and also the speed at which body fat decreases. 

Key Ingredients in Pre Workout

When you’re researching your pre workout, it’s important to pay attention to the ingredients it contains. Essentially, a pre workout is designed to help your body sail through a tough workout.

The primary active ingredient in most pre workouts is caffeine, but there are also other energy-increasing stimulants. Below is a list of some of the other key ingredients and their importance you’ll want to consider in a pre workout supplement.

Creatine Monohydrate 

This popular supplement among gym-goers is popular in many pre workouts. It helps by increasing muscle power and performance during your training session.


This acronym means branch chain amino acids. These help to improve your body’s endurance. They work by strengthening cellular energy and encouraging the regrowth of supporting protein synthesis.Taurine 

This plays an important role in the function of your heart and brain, as well as supporting nerve growth. It also aids your body’s metabolism of fats and helps to alleviate oxidative stress. Oxidative stress is the imbalance of antioxidants and free radicals in your body that can lead to tissue damage during intense workouts like Crossfit.

B Vitamins 

You’ll probably see a whole list of B vitamins in the ingredients of pre workout supplements. B1, B2, B5, and B6 are all important for energy production. B12 improves blood production and B3 boosts repair.

Arginine and Citrulline 

These fall under the category of NO2-boosters. In layman’s terms, this is a nitrogen dioxide booster. They help to expand your veins and arteries which makes it easier for blood to flow around your body. This helps to deliver nutrients quicker and more efficiently during your workout.

Things to Be Aware of in Pre Workout

One thing to be aware of when you’re choosing your pre workout is how much caffeine is in a portion. A report by Food and Chemical Toxicology states that the upper limit of caffeine for adults is 400 mg. 

To put this into context, a regular cup of instant coffee contains between 60-80 mg of caffeine. A flat white has about 65 mg of caffeine. A single espresso shot contains an average of 75 mg, with a double espresso containing up to a whopping 185 mg.

Some pre workouts contain up to an astonishing 410 mg of caffeine per scoop, which exceeds the daily recommended amount of caffeine intake. Taken regularly, this can lead to some negative side effects, including disruption to sleep, anxiety, and high blood pressure. 

Is It Dangerous to Take a Pre Workout?

Like lots of things in life, pre workout is perfectly safe to take, as long as it’s taken in moderation. It’s not recommended to consume a pre workout every day. Taking a pre workout every day over a prolonged period can lead to health issues.

Everyone has different tolerances and thresholds for caffeine. If you find you are taking a pre workout supplement a few times a week, and you’re suffering from jitters or heart palpitations, drop the amount you’re consuming. You can do this by taking it fewer times a week, or by reducing the amount of powder you use in each dose.

When Should I Take Pre-workout?

The optimum time to take your pre workout for a standard Crossfit session is between 30 minutes to an hour before your workout. If you’re doing an endurance workout, then you might want to take this mid-session to give your body an extra boost and the energy it needs to sustain prolonged exercise.

Should I Take Pre-workout Every Day?

No. If you take your pre workout every day, you will find your body builds up a tolerance to it. Also, as we mentioned earlier, taking excessive amounts of caffeine every day can bring on other lasting side effects. For best results, we recommend taking your pre workout in cycles to give your body time to rest and reset. Take it a few times a week on your intense workout days, for a couple of months.

Then give your body a break for a month or so before returning to use it. For the time you have off of your caffeine-infused pre workout, use a stimulant-free pre workout instead.
