Instructions

Attach the arm slings to a pull-up bar. Place your arms through them so the pads rest under your armpits, and hold the handles.

Keeping your torso stable, raise your legs by flexing your hips and bending the knees. Continue to raise your knees towards your chest by flexing at your waist and allowing your torso to raise. Bring your legs back down with control and repeat for the desired number of repetitions.
