The fitness industry runs on a well-documented psychological cycle: sign up in January, fade by March, repeat. The numbers behind it:
The headline numbers (2023–2025 industry data)
| Measure | Approximate figure |
|---|---|
| US gym memberships (health clubs) | ~68–72 million |
| US health & fitness club industry revenue | ~$30–35 billion/year |
| Members using their club regularly | ~half (attrition reality) |
| January sign-up share vs. annual average | Roughly 2x the monthly norm |
What the data shows
- The industry business model is attrition-tolerant: monthly memberships are priced expecting underuse — the January cohort funds the year. Members who train with structure (classes, trainers, programs) retain at multiples of solo-goer rates.
- Home fitness permanently split the market: connected-fitness and home-equipment spending spiked in 2020, corrected hard, but hybrid habits stuck — many members now split home and club days.
- Boutique and budget both grow; the middle shrinks: specialized studios and $10–30/month budget chains take share while traditional mid-price big-box gyms struggle.
