Tip for Monday. Lie on your back with your knees bent and feet on the floor. Keep knees, hips and feet aligned. On your exhalation slowly and gently contract the abdominal muscles. But here is the kicker! Don’t recruit gluts, hips, legs, shoulders, feet. Just use your abs. It is slow and subtle. See if you can contract a little then let everything else relax and then contract some more. Work up to 10 times. Good luck and happy core isolation!
