Partner Resistance

Lie on your back with your legs bent at 90 degrees, keeping your feet flat on the floor, shoulder width apart 10 - 14 inches from your buttocks.

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.

Your partner will resist the movement by holding the resistance band in a position that doesn't restrict your movement. You can also work the same action by securing the resistance band on to a secure object.

Beginners aim to work for 10 - 12 reps each side, for 2 sets, having 30 seconds rest between sets.

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

Advanced work for 15+ reps each side, holding in the final phase for 2 - 3 seconds for 2 sets.
