Begin in a bent over position with feet staggered and legs hip-width apart. Push the band forward in a horizontal line above your head to a full arm extension.
Tips:
Keep your upper arms and torso completely motionless.
The farther you lean forward, the more tension you will feel in your upper back.
Step forward or adjust A.P. height to alter resistance.
Variations:
Use an overhand/underhand or wide/narrow grip.
Interlock two bands at their midpoints or fasten two bands to a rear post.
