Frequently Asked Questions About Pre-Workout
People tend to have a lot of questions regarding pre-workout, especially as there are a lot of common misconceptions, but we're here to clear up some of the more typical queries you may have.
How Long Does Pre-Workout Last?
There is no one true answer to this question as the effects of pre-work will vary depending on your height, weight, tolerance to caffeine, and so on.
The majority of pre-workouts recommend consuming them anywhere from 30 to 45 minutes before exercising to reap the full benefits of the stimulants and to get the most out of your workout.
Thereafter, pre-workout can last between 3 to 6 hours depending on the person, meaning you should have plenty of time to complete even the most grueling and long workout whilst still feeling some effects of the supplement.
What Are Some Common Ingredients To Look Out For In Pre-Workout?
Different companies use different formulas for their pre-workout and therefore you will struggle to find one blend with the exact same ingredients and quantities as another.
One of the most common ingredients to look out for is caffeine because with increased caffeine comes increased short-term energy boosts, however, some pre-workouts are caffeine-free for those who look to reduce their caffeine intake.
Another typical ingredient is beta-alanine which helps you withstand the 'burning' feeling you get when pushing your workout to failure, and therefore should allow you to pump out a few more reps in each set.
What Are Nitric Oxide Boosters?
If you come across ingredients such as l-citrulline then you are looking at a nitric oxide booster which, in theory, increases bloody flow to your muscles and therefore improves the 'pump' during high-rep lifting.
L-citrulline for example is the natural form of citrulline and its primary function is to boost nitric oxide levels which help dilate your blood vessels, meaning your muscles get more oxygen and nutrients which also combat fatigue.
How Much Water Should I Mix With My Pre-Workout Powder?
There's no right or wrong answer to this question as it is really down to personal preference at the end of the day.
Ideally, you'd probably want at least 150ml of water to prevent the mix from being too strong and, in many cases, sweet.
C4, for example, recommends 6-12 fl. oz of water with their Original blend, which equates to around 170-355ml.
