Stretch your arms straight out
from your shoulder sockets
Out on either side of you
Like an airplane
Make small circles
With your hands
Keeping everything rigid
Strengthening the shoulders in the sockets
Do this for a while
Circling both forwards and backwards
Then
Bend your arms at 90 degree angles
Elbows parallel to the floor
Palms facing front
And rotate your torso and arms
Left
Then right
Swinging back and forth
With your legs staying in place
Feet hip distance apart
Try it while
Moving your elbows to different heights
Above and below
