JJ's High Performance

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. Far bigger than it should be.

st how big the gap is between local and elite levels when it comes to strength and conditioning. 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.

Simple, but do you actually do this?

One of the best goal-kicking tips you’ll ever hear is also one of the oldest.

Too many players aim in the general direction of the goals.

Instead, find the smallest target you can behind them. A spectator, a tree, a bin, or a teammate on the goal line.

Then focus on kicking the ball directly over that point.

The smaller the target, the sharper your focus.

Aim small. Miss small.

Born tough or built tough?

No player is born with a natural gift for winning contested footy.

But players who struggle in this area often convince themselves that some players just have it and some don’t.

The reality is much simpler.

Winning contested footy is a skill.

And like any skill, it’s built through repetition.

Getting in the contest.
Competing.
Making mistakes.
Learning from them.
Doing it again.

Strength and power help. Better technique helps.

But neither matter if you’re constantly avoiding the moment.

The players who thrive in contested situations aren’t usually the ones born tougher.

They’re the ones who’ve spent years putting themselves in the contest until it became second nature.

Get to work.
