This exercise is excellent for strengthening the upper back and arm muscles.
Method
Drape the band over a secure, stationary object, such as a wooden beam or a chin up bar.
Stand with your feet shoulder width apart and your arms fully extended upward, grabbing one end of the band in each hand and gently leaning slightly back.
Slowly pull the band back, bringing your elbows to your sides at your chest level before returning to the original position.
Starting with a light resistance to complete the reps is a great idea as this will allow you to master the techniques in this exercise. It's important to maintain a neutral spine throughout this exercise. Keeping your back inline will make sure that you exercise the right muscles and also prevent any injuries from occurring. You can do this exercise kneeling from the floor if you find this more comfortable than the squat position.
