This move mixes abdominal work and a cardio burst to help burn body fat while you strengthen your core so you can shed that muffin top faster.
How to do it: Start in a plank position with your feet together. Bend both knees and shift your weight into your arms as you jump both feet in to your hands, lifting your hips up to the ceiling. Land in a tucked position on the balls of your feet, knees bent and between your arms, and then quickly jump back out to your full plank position, keeping your abs tight and not letting your hips sag. That's one rep. Do 3 sets of 10 reps as quickly as you can with good form.
