Does Pre-Workout have calories?Updated a year ago

Most high-quality pre-workouts are relatively low in calories; however, this depends on each pre-workouts unique blend of ingredients. Some pre-workout supplements may contain zero calories and therefore won't break your fast if you prefer to train in a fasted state.

For optimal performance in the gym, it is vital to fuel your body appropriately beforehand unless you prefer to work out in a fast state. So, in addition to your pre-workout supplement, opt for easily digestible carbs about 30-60 minutes before your workout, as pre-workout nutrition can make a massive difference to your performance and results.(Kerksick, C et al. 2017)
