Gyms have more members than they have capacity to serve — by design

A typical Planet Fitness has ~6,500 members in a space that can hold ~300. The model only works because most people pay and don't show up. Boutique studios are the same model with a higher price tag.

If you're going 3+ times a week and it's load-bearing for your physical and mental health, it's worth every penny. If you've been five times this year, the math says cancel and walk outside.

The point isn't to never have a gym. It's to match your spend to your actual usage.

Frequently asked questions

How do I know if I'm getting value?

Cost per visit. $80/mo ÷ 16 visits/mo (4x/week) = $5/visit — great value. $80/mo ÷ 2 visits = $40/visit — terrible. Most fitness apps will tell you your check-in count.

What's the cheapest alternative?

YouTube + bodyweight exercises is free and proven effective. A $300 set of adjustable dumbbells pays for itself in 4 months of cancelled memberships.
