J17 Fitness runs athletic performance training for competitive athletes at four GTA locations — Markham, Richmond Hill, Oakville and Mississauga — programmed around the competitive calendar.
Strength, speed and power, programmed in season, out of season, and the part in between that decides both.
Tested at the start, retested through, so you and your coach are looking at the same numbers.
Under load, with technique that holds when you’re tired.
Sprint mechanics, change of direction, jump and throw.
The work that keeps you available, which is the only ability that matters.
The Performance Index™ benchmarks strength, movement and power at intake, then retests on a schedule.
You get the numbers. So does your sport coach, if you want them to.
All four J17 locations: Markham, Richmond Hill, Oakville and Mississauga.
In season the work drops in volume and holds intensity, usually two sessions a week, so training supports competition rather than competing with it.
Yes. Performance Index™ numbers are yours, and we can share them with a sport coach or physio if you want us to.
