Welcome to JJ's High Performance
My name is Jack Grimes.
I played 9 years at the Melbourne Football Club in the AFL, including three years as co-captain. While still playing, I opened my own personal training studio, where I coached everyone from first-timers to aspiring pro athletes.
After my AFL career, I returned to local footy — and it quickly became clear just how big the gap is between local and elite levels when it comes to strength and conditioning.
Far bigger than it should be.
Too many players were working hard, but not seeing the results they deserved — not because of a lack of effort, but because that effort was going into the wrong areas.
That’s when I set out to build something that would change the game for local-level footballers chasing their full potential.
A platform that’s affordable, easy to use, and flexible enough to fit around school, work, or uni.
I’ve been fortunate to learn from some of the best strength & conditioning coaches in the country. And I’ve leaned on those around me too — including my brother Dylan, who had a 13-year career at Richmond, earning three premierships and a Best & Fairest.
Now, through the JJ’s app, I won’t just tell you what to do,
I’ll coach you through it.
My name is Jack Grimes. I played for the Melbourne Football Club for 9 years, including a 3 year stint as co-captain. Whilst playing I opened my own personal training studio, coaching everyone from first timers to aspiring pro athletes.
After a stint at local footy, when my AFL days came to an end, I realised there’s a huge gap between the local and elite level when it comes to strength & conditioning. Way bigger than it should be.
So I started developing a platform that would change the game at local level for players wanting to reach their full potential. One that would be affordable, easy to use and allow them to fit it around work, school or uni.
I’ve been lucky to have learnt from some of the best strength & conditioning coaches in the country. But I’ve also lent on the experience of those around me to put this together, including my brother Dylan who had a very impressive career at the Richmond FC after 3 premierships & a B&F over 13 years.
