Lie face down, legs together and extended straight, arms bent with hands behind neck, head and neck in a neutral position.
Exhale: lift the upper body (chest, shoulders) off the ground, “crunching” towards the hips. Hold for 1-2 counts at highest position. Inhale: Slowly lower with control to start to complete one rep.
This is a very small movement, don’t move further than you can naturally and easily. Keep legs squeezed together, hips on floor. There should be no movement from your hips to your toes.
