Accessible movement summary
Lie on your back with hips and knees bent to about 90 degrees and arms reaching toward the ceiling. Exhale gently to bring the ribs over the pelvis while keeping the lower back comfortably connected to the floor. Slowly reach one leg and the opposite arm away without changing the trunk position. Return to the start under control, reset your brace, and repeat on the other side.
Key cue: Keep your ribs quiet.
