Building muscle burns body fat.

Increasing muscle per se does not reduce body fat, but muscle tissue uses more calories than fat tissue because it is more metabolically active. You must combine bodybuilding with aerobic activity and a reduced-calorie diet to lose weight.

The best type of aerobic workout to promote weight loss is high intensity and short duration.

When lifting weights, your muscles should feel fatigued for you to derive benefit from the exercise:

Experts agree that after eight to 12 weight-lifting repetitions your muscles should feel fatigued to derive maximum benefit. If they don't, you should increase the weight you are lifting.
