Ask any CrossFit coach at the end of a Foundations cycle who is going to be here in a year, and she will tell you — and she will be right. Who asks questions. Who shows up at 6am without being asked. Who is quietly scaling everything and looking at the door. The coach knows by week three. The problem is that what the coach knows lives in the coach's head, the membership keeps billing either way, and the owner finds out when the membership goes to "on hold" three months later.
A box's year is decided in the on-ramp. Not in the ad budget, not in the programming, not in the new rig — in what happens to six or eight people in the six weeks after they start together. Here is how to put what the coach already sees on a board the owner can act on, and the three numbers that make the first ninety days a thing you manage rather than a thing you find out about.
1. The on-ramp cohort, watched by week
Keep the group that started Foundations together as a cohort after it ends, and watch it week by week: how many are still attending, and at what pace. The curve has the same shape in every box we have looked at, and the shape is the point.
Two things the curve says. The loss is concentrated in weeks three to six — after the novelty, before the habit. And it flattens hard after that: the athletes who reach week twelve at a steady rhythm tend to be the ones who are still there in year three. That flattening is why the on-ramp weeks are worth more attention than any other six weeks of a membership, and why "the coach could name each one" is the sentence that should bother an owner most. The information existed. It was in the wrong place.
2. The three signals in the first six weeks
Put the cohort on a board and three signals do most of the work, each with a different note attached.
- The first missed week. An athlete in her first six weeks who goes seven days without a class has broken the only habit she had. It is the single most predictive event in the whole first quarter, and it is the easiest to catch, because the answer is a date.
- A doubled gap. Compare each athlete to her own pattern from the on-ramp, not to the box average. The three-times-a-week athlete at once has changed; when the gap since her last class reaches about double her usual gap, that is the week. The churn piece covers the fade patterns in detail.
- No home class time by week four. This one is specific to boxes, and it is the quiet one. Community is the retention mechanism in CrossFit, and community forms at a class time — the 6am crew, the noon regulars, the 5:30 people who go for a drink after. An athlete who has come at a different hour every visit has not joined any of them. By week four she should have a home time and a name in it; if she does not, that is the coach's job this week.
Notice whose name is on the note. The check-in that works comes from the coach who ran Foundations — "Hey Dana, missed you last week, the Thursday class has your name on it" — because that is the relationship the athlete has. The same words from the front desk are a reminder; from the coach they are an invitation. The box's job is to make sure the note gets sent in week three by somebody, instead of being a thing the coach meant to do between classes.
3. Holds are a churn signal, not an admin task
The membership model hides the fade almost perfectly. An unlimited monthly membership keeps billing whether the athlete comes fifteen times or once, so revenue says nothing for months. The first thing revenue notices is the hold request — and by then the athlete has been fading for six weeks and has decided. A hold is a cancellation that has not admitted it yet. Track holds per month as their own number, treat every hold request as the moment for the coach's conversation rather than a form to process, and count a hold that never comes back as churn on the day it was taken. A box with low cancellations and rising holds is not retaining anyone; it is deferring the paperwork.
The numbers, and the two the owner watches
| # | The number | How to compute it | The decision it feeds |
|---|---|---|---|
| 1 | 90-day retention by cohort | athletes still attending at week 12 ÷ athletes who started Foundations | whether the on-ramp is working, intake by intake |
| 2 | First missed week | new athletes with 7+ days since a class, weeks 1–6 | the coach's note this week |
| 3 | Home class time | share of new athletes with one class time for most visits by week 4 | who to introduce to a crew |
| 4 | Holds per month | hold requests · holds that never return | the conversation before the form |
| 5 | Trial follow-up speed | hours from a trial or drop-in to a personal contact | whether the funnel starts at all |
| 6 | Coach payroll vs revenue | coaching pay ÷ membership revenue, monthly | the biggest cost line, as a share |
Two of those belong to the owner rather than the coach. Trial follow-up speed, because the funnel starts with a drop-in who was enthusiastic on Monday and never got a call by Friday, and the research on response time is unambiguous — the lead follow-up piece has the study and the cadence. And coach payroll against revenue, because coaching is a box's largest cost line and it climbs one class at a time, each addition reasonable, until the share is a problem nobody chose. Watch it monthly as a share, not as a total.
If the box also runs race-prep classes, read those on their own: the HYROX classes piece covers why they fill toward a race and empty the week after.
Where the numbers live
Every number above comes from the attendance history the gym's platform already keeps: who started Foundations together, who attended what and when, who took a hold. The cohort, the three signals, and the holds column are all derivable from it. What has to be added is the reading — each athlete against the cohort's pace, every week — and the note, in the coach's name, in week three, which is exactly the work that gets left to whoever is between classes.
That is the shape Xyzios gives a box. It connects on top of the platform you run — Xyzios works with Mindbody and Mariana Tek today, with more platforms on the way — reads the box's own history as changes arrive, watches every athlete against her own pattern, warns when a new member's first week goes quiet, and drafts a save note for the one who is fading, in the studio's voice, ready for your approval. The coach's check-in stays the coach's; the fade is just not left to whoever is between classes. Nothing reaches an athlete without your approval, and nothing is written to Mindbody except what you tap or approve.
Wherever you run the numbers, keep the cohort together and watch weeks three to six. The coach already knows. The box's job is to know it at the same time she does. See how the board reads a CrossFit gym, or read the twelve numbers that run a boutique studio.
