Back Exercises: Seated Rotation
To start, 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, elbows just below shoulder height.
Turn from the waist with hips forward. Turn your head last.
Hold for a count of 5. Return to starting position.
Repeat 5 times on one side. Then switch sides.
