Start in a seated position, with your feet out in front, kness slightly bent
Hook the resistance band over both feet and spread your legs slightly wider than shoulder width
Ensure your back is prefectly straight, no arching
Keeping your legs still, slowly pull your arms back until your elbows are as far behind you as they will go, your hands should be by your side at this point
Now return your hands forward towards your toes until your shoulders are hunched forwards but your back is still upright and straight
Tips
To get the most out of this exercise, make sure your elbows stay close to your body and take them as far back as possible
