VARIANT 01
A.K.A. Leg Climbers (left leg in the air)
Lie on your back with one leg straight up toward the ceiling and the other bent with the foot on the floor. Grab the raised leg and climb your hands up it, curling your upper body toward the foot, then roll back down. Finish every repetition on one leg, then switch. Keeping the bottom leg straight, or reaching straight up for a single grab, makes it harder.
