This move not only works your waistline, it also adds a cardio kick to your training to help you burn up more calories and
slim down your abs.
How to do it: Start kneeling on your hands and knees, and then extend both legs straight behind you into a full plank position. Keeping your shoulders over your hands, pike your hips in the air as you jump both feet in towards your hands, bending your knees as you land on just the balls of your feet. Jump both feet back out to starting plank position. That’s one rep. Repeat 20 times total.
Bonus tip: The faster you go, the harder you’ll work. Pick up your pace (without losing your form) for a bigger calorie blast. (For an even better calorie burn, repeat this move again at the end of the circuit).
