A dedicated Revbox studio is one step closer to Christchurch  - I took the first trial indoor session last week, which contained a few surprises.  This was a chance to do a session with the majority of participants on a Revbox Erg (one had his regular mag trainer), in a dedicated environment.  

I’ve blogged previously about indoor sessions I take during winter for clients who ride their own trainers. So I’m use to taking not just a spin class, but a dedicated session focusing on intervals for cyclists, in a class environment.

The first of many….

What were the new things I experienced with a majority of participants on Revboxes? I initially thought that maybe the feedback (wind noise) from the trainers might present a few challenges, but I wasn’t expecting the opposite!

I normally don’t use a microphone of any sort but rely on good voice projection during my regular sessions where clients bring their own (variety of) trainers.  When numbers get over 15 I struggle to get my voice out there.  Last week with 7 clients on 6 Revboxes and in a longer room, I did resort to using a microphone.

However, what was a surprise was while doing a sprint session, as I knew before from my own experience using the Revbox, the astounding change in noise when we finished the sprints.  In a Revbox studio this change was amplified by 7 as all of a sudden the room became deadly silent - due to their low inertia they stop - along with the noise.  This was very cool.

The second really useful and very unique aspect of an session with all participants on a Revbox Erg, was the standardisation of gear selection.  I can not overstate how awesome this is for an instructor and coach - read carefully why I can’t overstate this awesomeness:

If we take a look at a traditional spin class on something like a Schwinn spin bike where resistance is set by the participant and cadence is also self selected, neither are measured.  At least in the training sessions I take, resistance (power - if they have a power meter) and cadence can be measured, which makes sessions more specific to an athlete’s needs. However, comparison between individuals (for those with a competitive bone) is impossible, nor is it possible for an instructor to indicate exactly which gear they should use (although power relative to individual’s functional threshold power (FTP) and cadence can be suggested).

What is unique about the Revbox is that, even if not all the participants in the class have power, the instructor/coach can more easily indicate a limited choice of what gear to use. It’s never going to be the same for all - notwithstanding a multitude of different front chain ring combinations, nor would you expect all participants to want to or be able to exercise at the same relative intensity on any given day.  But for the sake of simplicity - which is so necessary in a sweaty, loud and physically hard environment - giving participants one, two or a maximum of three gear options is magic.

In my next blog I mention another noticeable difference between an indoor session using a variety of trainers vs a Revbox studio, and how the use of a group of Revbox erg users compares with and would work in, a Zwift group ride or indoor training session.
