Punch Off the Pounds
For arms and chest
Stand with feet shoulder-width apart and knees slightly bent. Bring fists to cheekbone level, with elbows in toward chest. Punch right arm forward, thumb facing up; as right arm comes back, punch with left arm. That’s 1 rep. Do as many reps as you can in 20 seconds, rest for 10 seconds, then repeat 3–5 times.
Trainer tip: To really get your heart pumping, punch for 1 minute, then rest for 1 minute. Repeat 3 times.
