A pre-workout snack is important as it provides the necessary energy and nutrients to fuel exercise. Ideally, a snack should be consumed about 30 to 60 minutes before the workout, consisting of easily digestible carbohydrates and a source of protein. This combination helps enhance performance, maintain blood sugar levels, and minimize muscle breakdown. Popular options include a banana with nut butter or a yogurt with fruit. Proper timing and composition of pre-workout nutrition can optimize performance and recovery, making it a crucial component of a fitness regimen.
