Rapid Fire Punches: 30 Seconds
- Stand with your abs tight and your back flat in a quarter isolated squat. Guard your face with your fists, and keep a soft bend in your knees.
- Keeping the weight in your right foot, pivot your left foot, rotating your abdomen toward the right as you throw your left punch across your body.
- Return to center, and repeat on the opposite side, maintaining a tight and stable core throughout.
- Continue for 30 seconds as fast as you can, and then rest for 30 seconds.
