Fitness is BS.

I use behavioural science to fix the decisions that cost gyms members.

Most people who join a gym fully intend to use it, and plenty of them stop coming anyway. Behavioural scientists call that the intention-action gap, and most of the problems I’ve dealt with in thirty years of running gyms and pools start there.

The acquisition problem

Ads and search can get someone onto your website, and whether they join from there depends on what they see and feel before they reach the form. I work on the page they land on and the first visit they book, so more of the people who look end up joining.

The retention problem

High satisfaction scores don’t stop members cancelling. Whether someone stays comes down to the habits they’ve built around coming in, and I find out which of those are slipping in your gym and show you what to change.

Gym Hacks

Every fortnight I take one problem gyms keep running into and work out from the research what to change. Each takes about five minutes to read, and there are 77 so far.

The Cognitive Bias Library

Each of the 78 biases is written up in gym terms, with the research behind it and the places it shows up on a gym floor. It’s all free and you don’t need to sign up.
