What this programme is

Our HIIT floor is built around assault bikes, rowers, ski ergs and a small amount of loaded carry work. Every member wears a heart-rate strap, and zones are displayed live so effort is objective.

Intervals are programmed across the week so you are not sprinting flat out five days running. Hard days are hard; easy days stay genuinely easy.

Common questions

Do I need my own heart-rate strap?

No. Straps are provided and sanitised between sessions. You can pair your own device if you prefer.

Is HIIT suitable every day?

We cap members at three HIIT sessions per week and encourage strength or mobility on the other days.
