We picked up this quick, simple, and effective cardio move from Burn Pilates [1]. While it's not quite a 180 squat jump [2], which makes it easier on your knees, this 180 jump gives a burst of cardio while you keep your abs tight to stabilize your core. You'll work your glutes and quads while whittling your middle and burning fat calories from cardio.

Ready to get started? Here's how:

• Begin facing the left side of your mat (or space) with feet hip-distance apart, core tight, slightly hinged at the hips.
• Jump 180 degrees to your right, keeping your elbows near your rib cage and hands in front of you for balance.
• Jump 180 degrees to your left; make sure to be light on your feet, moving quickly.
• Repeat the jumps back and forth for 60 seconds.
