This exercise is intended to increase the challenge of the roll up. The theraband helps organize the shoulder, and keeping the arms by the ears challenges the spinal articulation
To do this exercise you will need a mat and a theraband. Start by lying on your back with your legs long beneath you and your arms on the ground behind your head with the theraband stretched between your hands. Inhale into the back of your ribcage, and exhale as you lift your head, neck, shoulders, and arms towards the ceiling, and then continue the exhale as you roll through the spine vertebra by vertebra reaching the head, neck, shoulders, and arms towards the ceiling.
Things to think about
If you have osteoporosis try this exercise by starting in a sitting position, and then hinge with a neutral spine towards the ground behind you.
Pulling outward on the theraband helps organize the shoulders so that you can find the articulation in the spine.
No matter how much you try your arms are going to get ahead of you. Try as much as you can to keep them reaching towards the ceiling.
