PROGRAM 2 UNIT 4
Women typically don’t gain size from strength training, because they have less testosterone than men, the hormone that causes bulking up. The good news is, studies show that women who strength train two to three times a week for eight weeks gain a considerable amount of lean muscle mass while losing fat. Your new muscles will help fight obesity. As you add muscle from strength training, your resting metabolism will increase, so you’ll burn more calories for up to 72 hours past your training session.
