The team behind Core Advantage’s Osgood and Sever’s programs
Core Advantage is a coaching team that's helped 6,000+ athletes across 45+ countries overcome Osgood Schlatter and Sever's Disease. We've been coaching young athletes in person since 1999 and online since 2016. While conventional wisdom says "just wait until you grow out of it," we've proven there's a better way: evidence-based rehabilitation that eases pain in weeks, not years.
From a local gym to a global solution
We refined our Osgood and Sever's training protocols in person at our Melbourne performance facility from 1999. We watched athletes who'd been told to "rest and wait" return to full competition in weeks, so in 2016 we launched our online programs to give athletes worldwide access to the same professional-grade rehabilitation. That's over a decade online, on top of more than two decades coaching in person.
The method hasn't changed because it works: address the root causes of the pain, rebuild the way the athlete moves, and progress carefully back to sport. Over 98% of the athletes who follow our program see a 50% reduction in pain within the first two weeks, then go on to fully eliminate it. Today thousands of families follow that same path from home.
A note before you start: our program is built specifically for Osgood Schlatter and Sever's Disease, so please have your knee or heel pain diagnosed by a medical professional first.
Treat growing pains like the injury they are
Our team of accredited sport scientists has specialised in growth-related sports injuries since 1999. The standard advice — rest, ice, “they’ll grow out of it” — costs kids seasons and confidence.
Durham McInnis and Core Advantage’s head of education Jacob Tober developed these programs after seeing hundreds of athletes told to just rest and wait — losing months or years of their sport, only to see their pain return when they start back.
We treat Osgood and Sever’s as injuries that can be rehabilitated, helping athletes of all ages actively strengthen, mobilise, and learn the key movement skills that not only rapidly eliminate their pain but also make them stronger and more resilient.
We rehabilitate growing pains the way elite sport rehabilitates injuries: find the cause, strengthen it progressively, and return to play stronger. The results come fast and they hold.
The people behind the program
Both Durham and Jacob are still actively involved in the program today. You'll most likely come across them in the support group when you start.
