Weight-Lifting Myth Busted: Lifting light weights with more reps builds muscle

Lifting light weights with more reps builds muscle.

It’s commonly believed that lifting heavy weights is the only way to build muscle, but a Canadian study has busted that myth. Researchers at McMaster University in Hamilton, Ontario, found that doing more repetitions with a lighter weight works just as well-as long as the exercise is done to a point of muscle failure, meaning the muscle can’t do another repetition with proper form. In the study, 15-20 repetitions with a lighter weight were just as effective as 8-12 repetitions with a heavier one. Researchers believe the lighter-weight method has greater appeal to novice exercisers, rather than to elite athletes.
