Groin pain or OP as it is commonly known in AFL circles plagues athletes and can sideline an athlete for an entire season.  

In my travels, I was lucky enough to work out of a clinic that was owned and run by an OP guru.  He taught me his OP protocol and how to deal with the most stubborn case, I am extremely grateful to this individual, role model, and mentor

FYI - I have another website that has more information about Groin Pain

Rib fractures plague Rowers, typically lighter Rowers and can severely impact a Rowers career.  I have had the opportunity to work with many Rowers and consequently, I have encountered many cases of rib pain and rib fractures.

The body is a system of systems and nothing exists in isolation, this is true for a rib fracture, the body compensates, becomes tight through the erector spinae, and intercostals, weakness also accompanies the pattern.
