In a fitness studio, the diagnostic question is not "are classes full?" but "are members staying?" A studio can post packed 6 PM classes and still bleed out through churn — because every leaving member takes their recurring revenue with them.

Utilization is the quiet lever

Class fill rate and break-even member count matter more than headcount at the door. A studio that is 60% full at peak but 20% off-peak is under-utilizing fixed space — the fix is scheduling and off-peak promotions, not more square feet. Pre-sale memberships compress break-even from 6-18 months to 3-8 months.

Reprice, do not cut pay

Trainer pay of 25-35% is structural, not waste. A 10-20% price increase (rarely hurts retention when service is consistent) drops labor percent without cutting a single paycheck — and lifts net directly.

Watch churn weekly: a 7-10% monthly churn halves your base in under a year. Track it by cohort, not by total member count, or you will mask losses behind new sign-ups.
