Gyms and coaches

For gyms and coaches

MaxCals is erg and air-bike engine work that members do alongside your programming.

MaxCals doesn't programme your running, sled, strength or skills work. It builds your engine on an indoor machine alongside it.

Run a test day

The four engine tests fit the rowers, SkiErgs, BikeErgs, air bikes and Wattbikes a gym already has. Use the same machine each time so results compare like with like.

  • P160-second sprint

    Your top-end power: the most you can produce when duration doesn't matter.

  • P310-minute max

    The hardest effort you can sustain for 10 minutes. Set against the 30-minute test, it gives your aerobic profile ratio.

  • P4Tabata

    How well you recover between repeated maximal efforts, read as the Tabata decay index.

  • P230-minute time trial

    Your aerobic base: the output you can hold for half an hour.

A coach should supervise the session and screen members first. These are maximal efforts. If you have a health condition or any doubt about training this hard, check with a doctor first, and stop if you feel unwell.

What we do not do

  • MaxCals never receives your member list.
  • Members sign up to MaxCals directly. There is no app to install and no account to create.
  • It doesn't replace your coaching, or your programme's strength, running or skills work.
  • It is for adults aged 18 or over who can already hold a steady effort for 30 minutes on their machine. It is not built for complete beginners to rowers, ergs or air bikes.
