Caffeine has been shown to be an effective ergogenic aid, but new evidence suggests it may also help with post-workout soreness. A WebMD article explains the latest research. If you are a person who tolerates caffeine well, you might consider a cup of coffee (two were used in the cited study) a little before your workout. If coffee's not your thing, try drinking a cup a half hour before your next moderate-intensity aerobic event (non-competitive!) to see how you feel. Don't add it before a high-intensity workout or competition or high-risk activity until you know you tolerate it well. And, of course, don't use it if you have medical contraindications like palpitations, stomach or cardiac conditions.
