Boxers, kickboxers, and mixed martial arts fighters don’t use treadmills to get ripped. Their shredded physiques come from fight training, of which pounding a heavy bag is a major component. Dust off the one in your basement, lace up the gloves, and beat your gut once and for all.

How it Works

Hitting a bag builds punching power, stamina, and can increase your metabolic rate for days afterward. This workout involves your legs as well as your arms to train the whole body, activating as much muscle as possible to burn the most calories.

Directions

Perform the exercises as a circuit, completing one after the other without rest. Afterward, rest 30 seconds. That’s one round. Repeat for five total rounds. To avoid injury, wear hand wraps and bag gloves.
