Editor's Pick: Pop one open before your afternoon meeting—the caffeine releases gradually, so you won't get that jittery rush like coffee. Zero sugar and zero calories, so it's easy on you before or after a workout. It's packed with beta-alanine and betaine, which help keep your muscles from fatiguing in the later stages of your session. The 12-pack is super convenient for stashing in the office or your car, and the strawberry watermelon flavor goes down much smoother than your average energy drink.
