24 Fat-Burning Ab Exercises (No Crunches!)
Circles in the sky
For core, inner thighs, outer hips, butt
Lie on your back with hands behind your head. Contract abs, lifting upper body slightly off the ground. Raise right leg 5 inches (or keep it on the ground if that's too challenging) and left leg straight up toward the sky.
Keeping your core engaged and hips stable, trace 4 softball-size circles clockwise with your entire left leg; reverse, circling 4 times counterclockwise. Lower both legs, switch sides, and repeat.
