I've adapted the mat prone exercises to suit my male clients. For example, instead of full swim, I do arms only. No swan rocking, just the stretch. Instead of lots of prone, I have them plank or quadruped, or do sitting thoracic extension. Just to give you an idea. All my male clients are happy campers, have had them for years!
I really appreciate the modifications you presented. I work with quite a few guys, and these tips are really helpful. I especially appreciate that you explain WHY someone might want the modifications and what the reason is for the modifications.
