Before your test

How to prepare

  • Take it easy the day beforeVery light exercise or a rest day. Hard training the day before skews your results.
  • Fasted for 4 hoursNo food or caffeine in the 4 hours before your test. Water is absolutely fine.
  • Bring a heart rate chest strapIf you have one, bring it so your zones carry over to your own training. If not, we have them here.

What people are saying

I'd been training for an Ironman on guesswork. The VO₂ test showed my zones were completely off. I was going too hard on easy days and not hard enough on intervals. Fixed that and knocked 14 minutes off my half-iron time.

Mark T.
Triathlete & cyclist

I was eating 1,400 calories thinking that's what I needed to lose weight. The RMR test showed my metabolism was actually burning way more than that. I'm eating more now and finally dropping body fat. Wish I'd done this years ago.

Sarah K.
Weight loss · gym-goer

Ran my first sub-40 10K after adjusting my training zones from the test. The report was dead clear, no confusing graphs, just 'here's what to do.' James was brilliant at explaining everything too.

Dan P.
Club runner

Not a competitive athlete at all, I just wanted to understand why I was always tired by 2pm. Turns out I was barely burning any fat at rest. Changed my nutrition off the back of the results and my energy is so much better.
