Lay on your back with your hands under your glutes or lower back for support. Point your toes and extend your legs. Use your whole core to lift both legs up straight at a 45-degree angle. Lower your right leg back towards the floor without touching it. Raise your right leg as you lower your left leg in a ‘scissor’ motion and repeat. Keep your neck and shoulders relaxed and your core completely engaged. Continue for 30 seconds. Variation for an added challenge: Push yourself for one more minute with this variation! Instead of a vertical scissor kick motion, cross your right leg over your left then your left over your right and repeat in a crisscross motion. Continue criss-crossing your legs while using only your core muscles to hold and move both legs back and forth without touching the ground or allowing them to drop. Repeat for 30-60 seconds
