Open Book Stretch

What it is

Lying on your side with the knees bent, you open the top arm across to the other side, rotating the upper back. It improves thoracic rotation. Keep the knees stacked.

One side at a time: log each side, and match the reps of your weaker side.

Technique tips

• Lie on your side, knees bent and stacked
• Arms out in front together
• Open the top arm across
• Follow the hand with your eyes

How to track your progress

Log reps, and add the extra load if you wear a belt or a vest. Straddly counts your bodyweight in the estimated max, so added weight and extra reps both show up as progress, and new records are flagged during the session.
