Oopsy! In exercise physiology world loaded flexion and rotation is contraindicated full stop, not just for those with disc herniation. Dr. Stuart McGill taught me that, not personally, but his research.

Thank you Chris, for challenging us with such thought-provoking questions. It, encourages me personally to continue to be proactive about educating myself.
