The Side Stretch: A Gentle Exercise

The side stretch exercise stretches and strengthens the intercostal muscles, (the muscles between the ribs), which help support the ribs.

To do the side stretch:

  • Sit in a sturdy chair with your feet flat on the floor or stand with feet hip width apart.

  • Lean forward slightly to keep from "hunching" your back and shoulders.

  • Keep your hips, shoulders, and ears in a straight up-and-down line.

  • Raise your right arm overhead and bend your upper body to the left in a reaching motion. Keep your upper body facing straight ahead — don't twist it to the side as you bend.

  • Make sure you feel the muscles gently stretch all along your side from your lower back up to your shoulder.

  • Hold the stretch for 20 seconds, then return to the starting position. Repeat the stretch 2 times.

  • Switch sides and do the stretch in the opposite direction, repeating twice.
