Kneeling book openers isolate thoracic rotation from a tall kneeling or quadruped position. By anchoring the lower body, this drill ensures the rotation comes from the thoracic spine rather than the hips or lumbar spine. It is an excellent warm-up for any upper body training session.

Setup

  1. Start in a quadruped position (hands and knees). Place one hand behind your head with the elbow flared out to the side.
  2. Slowly rotate your upper body, bringing the elbow of the hand behind your head down toward the opposite arm (closing the book).
  3. Reverse the motion and rotate upward, opening your chest toward the ceiling and driving the elbow toward the sky (opening the book). Follow the elbow with your eyes.
  4. Move through the full range of rotation — closed to open — for the prescribed reps, then switch sides.

Coaching Cues

What to feel:

  • A rotational stretch through the mid and upper back
  • The opening (upward rotation) should feel expansive through the chest

Common mistakes:

  • Rotating from the lumbar spine or hips instead of the thoracic spine — keep your hips square and stable
  • Not rotating fully in either direction — push both the close and open end ranges
  • Moving too quickly without controlling the rotation

Progressions

  1. Beginner: Reduce the range of rotation; hand on shoulder instead of behind head.
  2. Intermediate: Full range kneeling book openers as described.
  3. Advanced: Hold a light dumbbell in the rotating hand, or add a 3-second isometric hold at the top of each rep.
