See pre-sale prices View timetable

Everyone is welcome. Effort is expected.

01 — The club

On3 exists to give people the chance to progress and challenge themselves daily — physically and mentally.

Capable means being able to do what you want, whenever you want: a first pull-up, the monkey bars with your kids, a hike with friends, being the one people call when they're moving house because you're strong enough to help.

At the end of every class we have “3 claps on 3”. It signals the end of the class and brings everyone together before we move on with our days.

As competitive as you want it to be.

Some people are here to win. Others are here to enjoy training and their own progress. Both belong.

Commit. Progress. Belong.

02 — Classes

Three ways to train.

Every class is coached and modified to you. Pick one, or mix all three into your week.

Hyrox

Train for the race. Build the engine.

Hyrox

8 × 1 km runs. 8 functional stations. One finish line.

lunges and carries,

station work to sharpen technique and efficiency,

and race-pace sessions so you learn to run on tired legs.

Whether it's your first race, you're chasing a PB, or you just want the fitness that comes with it, we'll get you there.

As competitive as you want it to be.
