A: Caffeine may not completely prevent muscle soreness, but research shows that it can significantly reduce how long it takes you to recover from a workout and lower how much soreness you feel afterwards. 

A 2011 study found that just 200 milligrams of caffeine (the amount in about two cups of coffee) could cut muscle pain by 50 percent and reduce delayed onset muscle soreness by 33 percent after exercise.

Other studies have found similar results: In one study, cyclists who consumed about 6 milligrams of caffeine per kilogram of body weight every day for six days were able to ride longer before exhaustion set in than those who didn't consume any caffeine at all.
