What 68,000 training sessions tell us about who keeps going
We run two personal training studios, one in Santa Monica and one in Mar Vista. Between September 2024 and August 2026 our members booked 68,199 sessions. We went through all of them to answer one question. Who is still training a year later, and what did they do differently in the beginning?

The answer was simpler than we expected.
- 63% vs 35%8 sessions in the first 30 days.
New members who trained at least 8 times in their first month were still training a year later 63% of the time. Below 8, it was 35%.
- 62% vs 17%Train more, stay longer.
In their first 90 days, members who trained 2.5 times a week or more were still training a year later 62% of the time. Members who trained less than once a week were still training 17% of the time.
- 60% vs 39%The first missed week matters most.
New members who trained in all four of their first four weeks were still training a year later 60% of the time. Miss any one of those weeks and it dropped to 39%.
- 12% vs 2%People who quit early often never started.
12% of members who left within three months never came to a single session in their first 30 days. Among members who stayed a year, it was 2%.
What we do with it.
The first month decides most of it. So that's where we put the attention.
Every new member starts with a free Baseline Session and leaves with a plan. After that we watch three things: anyone who hasn't come in by day 7, anyone who misses a week in their first month, and anyone under 8 sessions by day 30. A coach reaches out to each of them.
Our own members showed us where people fall off. So that's where the coaches look.
What this does not prove.
These numbers come from booking records at two studios. People who were never going to stick with it probably also trained less in month one. So we can't say 8 sessions causes someone to stay. We can say it's the clearest early sign we've found, and it shows up in the first two weeks.
If you're starting somewhere new.
Pick a schedule you can keep twice a week for a month. Book the sessions before you start. And if you miss a week, go back the next week anyway. That week is where most people quit.
