- Begin with your feet slightly wider than hip's width apart and toes pointed slightly outward. Bring your hands together in front of your chest.
- Keeping weight in your heels, sit back into a deep squat. Make sure your knees do not go beyond your toes or roll in or out of alignment. Keep your abs engaged as you squat.
- Deepen your abdominal engagement as you press through your heels to return to standing, completing one rep.
- Do as many air squats as you can for six minutes.
Now work you way back through the pyramid, starting with five minutes on the cardio machine of your choice.
