J17 Fitness runs tread-and-floor HIIT classes in Richmond Hill — thirteen treadmills and a floor section, coached, forty-five minutes, up to thirty-six people.
You run, you lift, you switch. A coach calls every block, the room is dark and loud, and by the time you’re doing the math on how much is left, it’s over.
The hardest part of conditioning is deciding what to do. Here you don’t.
The coach calls efforts, not speeds. Push to your number.
Conditioning is one of the things your Performance Index™ retests.
Come fifteen minutes early. We’ll set your treadmill, show you the bench, and give you the two numbers you actually need.
A tread-and-floor class splits the room between treadmills and a strength floor, and you swap between them on the coach’s call. At J17 the format runs forty-five minutes with thirteen treadmills.
The coach calls efforts, not speeds, so you set your own pace — and the floor section is a full workout on its own if you’d rather stay off the tread.
Up to thirty-six.
Bring indoor training shoes. Everything else is here.
