Why Stretch?
Stretching exercises encourage lengthening of your muscles and associated tendons. Short and tight muscles can lead to pressure on nerves and pain. By its effect of lengthening muscles, stretching promotes flexibility and full range of motion about your joints.
Perform 10 shoulder pass throughs 3-4 times per day
Hold a PVC pipe straight (broom handle works as well)
Without bending your elbows pass the bar over your head and down to your back
Then bring forward to front
If your elbows bend your hands are too close together and will not gain benefit of stretch
Widen hands until you can pass the bar through without bending elbows
The wider the hands, the easier the motion
Push up on bar to get it to pass over your head when your hands are wide
