This short routine from George Foreman III, a professional boxer and co-founder of boxing gym Everybody Fights in New York City, will blast your entire body in less than 10 minutes.
To get started, grab a set of two-pound weights and find a line or a rope to duck under at chest height. Begin by standing on one side of the line with your knees bent and your weights up by your chin.
Step to the right under the line with your right foot and punch your right arm forward. Then step to the left under the line and throw a left hook. Each time you throw a punch or a hook, snap your arm back toward your body quicker than the outward movement.
When you duck underneath the line, remember: "It's a squat, don't bend over with your back. That's a great way to get hurt," Foreman says.
Take your time for one-minute, step to the right and shoot your right punch, then step to the left and shoot your left hook. Repeat that for one minute straight, then do 30 air squats and repeat that cycle six times. That should equal two 3-minute rounds in the boxing ring.
