Powerlifting, a strength sport where you compete in the squat, bench press and deadlift, allows you to build muscle and burn fat. Powerlifting, like other forms of heavy resistance training, strengthens your skeleton and reduces your risk of injury in other sports and activities. While the rules for the powerlifts remain specific, the general benefits of powerlifting go far beyond conventional lifting. Consult a health care practitioner before beginning any strength training program.
