To do a Seated Rotation, sit in a chair with your feet flat on the floor. Shift your weight slightly forward to avoid rounding your back. Relax, and keep your ears, shoulders, and hips aligned.
Fold your arms, with your elbows just below shoulder height.
Turn from the waist with hips forward. Turn your head last.
Hold for a count of five.
Return to starting position.
Repeat five times on one side.
Then switch sides.
