Be sure the tube or band you are using is not too strong and is the appropriate length to avoid injury.
While holding your band firmly in both hands, bend your knees. Bend your torso over slightly and step on the band with both feet. The band should have moderate resistance because of your foot positioning. Keep your arms fully extended and do not pull on the bands until the exercise begins.
How to Do:
1. Once you are securely on the band in the correct position, pull each handle upwards towards your sides.
2. Once you have pulled the handles up to as close to chest level as flexibility will allow, slowly let the handles return down and repeat the movement.
