Each axis is this gym measured against 399 priced chain gyms in London — so it moves as that comparable market moves, not as we change our minds. The score above is the mean of the five, out of 5. The figures beside each axis are the same ones printed elsewhere on this page. How this is worked out. Nothing about this can be bought.

Price history
One recorded price observation so far, on 8 September 2026.
We need another checked observation before we can say whether this price has changed. We will show the first confirmed move here rather than calling a short record “no change”.
Watch this price — we will email you when it changes.
What is actually in there?
Gyms publish a facility list, not a kit list. If you train here, you know things their website does not say — and it is the question everyone asks before joining. Nothing appears on the page until we have reviewed it.
