Weight training: Are you using good technique? - MayoClinic.com: "You don't have to be a bodybuilder or professional athlete to reap the benefits of a weight training program. Weight training — a form of strength training — can improve your strength, increase your muscle tone, help you lose fat and gain muscle mass, and improve your bone density. But if done incorrectly, weight training won't give you these benefits and can lead to injury."
