The relationship, plainly: M4P is an independent training business founded and run by Connor Jenkins, who is also the High School Director at Southside Prospects. That overlap is the point — the person building the club's training system coaches inside it. Club dues go to Southside Prospects; M4P memberships, camps, and clinics are paid to M4P, with the discounted club rate applied for Southside athletes.
Getting started

The entry point is the M4P assessment — a movement screen, complete baseline, and film, with a full written evaluation — so training starts from measurements, not guesses. Book it directly with M4P.
