Individually foil-packed shots keep you strong and alert by replacing carbs and glucose lost during aerobic exercise. GU also contains vitamins C and E, which protect muscle tissue and prevent soreness.

What You Get: More liquid than solid, GU delivers energy without the excess bulk in your belly.

Eat Up: Gulp the GU 15 minutes before exercising and every 45 minutes throughout. 100 calories per pack

Tastebuds: Similar in consistency to a thick pudding with flavors like Vanilla Bean and Lemon Sublime, this isn¿t something to chew on. Gulp and go.
