Hands to Feet

Exhale and lift your shoulder blades1 - 3 inches off the floor throughout the exercise, breathing naturally during the movement.
With your arms off the floor down by your sides, use your left oblique muscles to twist from your waist, taking your left hand to your left foot, repeating again on the other side, by using your right oblique muscles.

Intermediates aim for 12 - 15+ slow reps, aiming to hold in the final foot touching phase for 1 - 2 seconds.
