A: Caffeine is also proven to boost endurance. In fact, there's a good amount of science behind it. More and more studies have shown that caffeine can improve muscular endurance when used in moderation (about 3-5mg per kg of body weight).

Plus, if you use caffeine before an aerobic activity like running or swimming—or even for strength training—you should notice improved muscular endurance as well.
