Band Resisted Rollout Tutorial

Tie a resistance band around the ab wheel and wrap it around the post of a squat rack or similar.
Kneel on the ground facing towards the rack and place your hands on the handles of the wheel.
Brace your abs and begin rolling the wheel forward by pushing your hips forward.
Roll-out until your body is forming a straight line between your knees and your shoulders, then roll the wheel back to the start position. The band will resist you on the way back in.

Think about keeping your hips and the bottom of your rib cage pulled together. This will keep your spine in a neutral position.
This is tougher than regular roll-outs. Only move on to this after you can do regular roll-outs with good form.

Letting the hips sag down as you’re extending. Make sure to keep the abs tight and don’t let your back sag.
