GET A LEG-UP

When you hit the workout wall, will you have what you need to push through? A new supplement—betaalanine— may make it easier to conquer the most challenging parts of your routine. The amino acid helps maintain strength during your workout 70 percent better than creatine does, report researchers at Florida Atlantic University. “By delaying fatigue, beta-alanine allows you to train harder,” says Jeff Stout, Ph.D., C.S.C.S., the study’s lead author. This means your strength levels will last long enough to finish all your sets and repetitions. Our pick: timedrelease betaalanine supplement.
