What’s In The Box

Rhythm HIIT heart rate monitor

Meet Your Heart Rate Monitor

Your new training partner. Here’s how it works, and why it’s about to change the way you train.

How It Works

Your monitor reads your heart’s electrical signal in real time and sends it straight to the screens in the studio. No guesswork, no manually counting beats. Just your real effort, live, every rep of every class.

  1. Wear it snug, just below your chest, or on your wrist if it’s an optical strap
  2. It syncs automatically the moment you walk into the studio
  3. Watch your live heart rate and effort zone up on the screen throughout class

Your Effort Zones, Explained

Your OnBeat monitor shows five zones, each a percentage of your max heart rate, not anyone else’s.

GreyWarm up & recovery
BlueSteady pace, building
GreenBase pace, challenging but doable
OrangePush pace, your afterburn zone
RedAll out, short bursts only

The goal isn’t to live in the red the whole class. It’s knowing exactly where you are, so you can push smart.

Find Your Orange Zone

Enter your age and we’ll calculate the exact heart rate range that maximises your afterburn (EPOC) without tipping you into overtraining.

Estimate only, based on the Tanaka max heart rate formula (208 minus 0.7 x age). For guidance only, talk to a coach or your doctor if you have any heart or health concerns.

The Science Behind It

Training in your Orange Zone doesn’t just burn calories during class. It keeps your metabolism elevated for hours afterward. That’s the “afterburn effect,” and it’s the whole point of training smart, not just hard.

Why It Makes You Better

  • Trains to YOUR fitness: no two members share a max heart rate, so your zones are personal to you
  • Accurate effort tracking: see exactly what you burned, not a rough estimate
  • Real-time motivation: watch your effort live and find that extra gear
  • Smarter recovery: know when to push and when to ease off, so you avoid burnout
  • Progress you can see: as fitness improves, the same effort produces a lower heart rate over time

Get Set Up In 30 Seconds

  1. No charging needed. It runs on a replaceable coin battery and comes ready to go straight out of the box
  2. Wear it snug against your skin every session
  3. Ask a coach to link it to your profile the first time
  4. Turn up, and let the screen do the rest

Works Beyond The Studio

Pair it over Bluetooth with your favourite apps too, including Nike Run Club, Strava, and Wahoo, or connect it straight to your Garmin watch for training outside of class.
