The total, as said in the episode

What the evidence shows

In the best data we have, most monthly members paid more per visit than a simple pass would have cost. Mostly because they planned for a better version of themselves.

Rows 3–7 · 11:13

What it suggests

Overconfidence, fresh-start optimism, and payments that stop feeling real all push the same way.

Rows 10–13 · 11:26

What nobody outside these companies knows

Who actually shows up, and who doesn't. Planet Fitness publishes no visit numbers at all, and Basic-Fit only gives an average.

Rows 20, 34 · 11:34

What I can't tell you

That gyms secretly want you gone. Planet Fitness's own filing calls absent members a risk, and Basic-Fit runs a whole department to bring them back.

It does: 1.2 visits per member per week in 2025 (1.0 in 2024), for its own clubs without Clever Fit, in the sustainability statement of its 2025 annual report.
