Directions
With a loop or tube resistance band, or even a long pole such as broom handle, place both hands on either end of the band or pole, raise them above your head and try to get the band or pole behind your back. You should feel it stretching the pectoral muscles, utilizing the rotator cuff of your shoulder. If it's difficult to get it behind your back, try to widen the span of your arms on the band or pole.
