Athletic performance and sports performance training across the GTA.

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.

Strength, speed and power training.

Strength

Under load, with technique that holds when you’re tired.

Speed and power

Sprint mechanics, change of direction, jump and throw.

Durability

The work that keeps you available, which is the only ability that matters.

Athlete testing with the Performance Index™.

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.

Athletic performance questions.

How often should an athlete train in season?

In season the work drops in volume and holds intensity, usually two sessions a week, so training supports competition rather than competing with it.

Can my coach see the results?

Yes. Performance Index™ numbers are yours, and we can share them with a sport coach or physio if you want us to.
