Reps: As many as possible in 30 seconds on each side
Begin on all fours, brace abs in tight, and lift knees a few inches off the ground (keeping hips below shoulders). Round spine and draw left knee in towards nose, scooping abs in towards back.
Return spine to neutral and extend left leg behind hip (right knee should still be lifted off the floor). Continue this movement for 30 seconds, and then repeat on opposite side. If it's too tough to keep the supporting knee lifted, keep it on the floor instead.
