How to do it: Lie on your back and bend both knees into your chest, feet flexed. Interlace your fingers on top of your right thigh and extend your left leg out parallel to the floor. Lift your head and shoulders off the floor, curling up over the top of your ribcage and looking at your legs. Press your palms against your right thigh while tipping your pelvis to bring your right knee in towards your chest (your hands should add resistance to your leg). Switch legs and press your palms against the left thigh as your right leg extends parallel to the floor. That’s one rep. Do up to 3 sets of 10 repetitions in a row.
