This Pilates-inspired move uses the same pressing action as the static press to deepen the engagement of your abdominals. The weight of your extended leg makes it more challenging.
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.
Make it harder: Keep both legs straight, pressing against the top of your thigh as one leg pulls in, and then perform a scissoring action to switch sides.
Mind your muscle tip: As you push against your thigh, imagine you are pulling your leg into your chest with your abs. Focus on feeling the extra resistance in the abs, not your thighs or hip flexors.
