Lie on your back. Keeping your torso straight, bend your knees and bring them to the right so they are resting on the floor. Clasp your hands together behind your head. Lift your shoulders off the floor in a crunch motion. Keep your shoulders even as if you are doing a regular crunch. With control bring your shoulders back down. Repeat.
Do this exercise with the best exercise equipment. We recommend using a bluetooth chest strap heart rate monitor or a smartwatch for more training optimization & performance tracking.
