Target your obliques [1] and your booty with just ONE move — no equipment necessary! This sumo squat with a standing oblique (read: side ab) crunch will help whittle your middle while helping you reach your booty-gain goals. And aside from the hourglass shaping, you'll create a strong core [2] and powerful butt and legs [3], which will power you through day-to-day functional movement and your workouts!

• Start in a wide stance with your toes pointed out; bring your hands behind your head with your elbows wide.
• Bend your knees over your toes, coming into a squat with your thighs almost parallel to the floor.
• As you straighten your knees to stand, lift your right knee while bending to the right to bring your right elbow and knee together, doing a side crunch.
• Straighten your spine as you bring your right foot to the floor, and bend both knees, coming into a sumo squat.
• This completes one rep.
