Tread-and-floor HIIT classes in Richmond Hill.

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.

How a HIIT class runs.

  1. Warm up together. Everyone starts on the floor.
  2. Split the room. Half on the tread, half on the benches.
  3. Switch. Two or three times, depending on the day.
  4. Finish together. The last block is everyone, all in.

Why tread-and-floor HIIT works.

No thinking

The hardest part of conditioning is deciding what to do. Here you don’t.

Your pace, not theirs

The coach calls efforts, not speeds. Push to your number.

It’s measured

Conditioning is one of the things your Performance Index™ retests.

Your first HIIT class.

Come fifteen minutes early. We’ll set your treadmill, show you the bench, and give you the two numbers you actually need.

HIIT class questions.

What is a tread-and-floor class?

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.

What if I can’t run?

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.

How many people are in a HIIT class?

Up to thirty-six.

Do I need my own shoes?
