London · By introduction only
Ninety is built around one measurement: whether the session actually happened. Every slot is fixed in advance, every completion is verified in the app, and every miss is followed up personally by your coach the same day.
Membership is by introduction only. 20 places, no more.
How it works
Clients rarely fail because the programme was wrong. They fail because the sessions did not happen. Everything here exists to close that gap.
Your sessions are placed in the calendar for the full twelve weeks before you begin. Same days, same times, agreed once. They are appointments, not intentions.
Every session is logged in the app — coached and solo alike. A session counts when it is completed, not when it is planned, and the record is visible to both of us.
A missed session gets a text from your coach within hours. Not a push notification, not an automated nudge. We establish what happened and put the session back.
Every workout has an eighteen-minute version requiring no equipment. On the weeks that come apart, you do the short one. A bad week never becomes a zero.
Measured, not asserted

Membership
Both include the fixed slots, the verified log, the follow-up and the eighteen-minute fallback. The difference is how much of the week is coached in person.

20 places. Currently 17 filled.
3 places are open. There is no public sign-up: a place is taken up by introduction, or from the waiting list.
Clause one
12-week block
Complete ninety per cent of your committed sessions across a twelve-week block. If you hold to that and still fall short of the target you agreed at the outset, the following block is provided at no charge.
The target is written down before the first session. Adherence is read from the verified session log, not from recollection. One block, one claim.
In members’ words
I have had four personal trainers. The programmes were all perfectly good. This is the first one where somebody noticed that I had not turned up.
I am away two weeks in three. The eighteen-minute version is the only reason I am still here. It is not the session I would choose; it is the session that happens.
Nine months in, I am at ninety-four per cent. I could not tell you my completion rate for anything else in my life, which is rather the point.
Questions
Join the waiting list. Places are offered in the order they are requested, with priority given to member introductions. We would rather be straightforward about it: an introduction moves considerably faster than the list.
Your coach texts you within a few hours — a person, not an automation. We establish what happened, reschedule where the week still allows it, and log it either way. One miss is data. Three in a row is a conversation about whether the structure we agreed is the right one.
Most members do. Every workout has an eighteen-minute version written for a hotel room with no equipment, and your travel is built into the block in advance rather than treated as an interruption to it. A difficult week should cost you a shorter session, not the habit.
Adherence only means something measured over a period long enough to contain a bad month. Twelve weeks is the shortest block in which the number is honest. After the initial term, membership continues on a rolling monthly basis and you may leave with a month’s notice.
Because the follow-up is the product. One coach can notice every missed session in a week across twenty members and respond to each personally. At two hundred members that becomes an automated email, and an automated email does not make anybody train.
