Attach one end of a resistance band to knee height or ask a partner to hold it.
Start on your hands and knees and hold the other end of the band in one hand with the slack taken off.
Lower onto your toes and forearms with your body in a straight line from your heels to the top of your head.
You can place your feet slightly wider apart to help keep your balance if required.
Hold this position as you straighten the arm holding the band over your head and then pull the band and bring your elbow to your side, and repeat.
