<small>7 minute read</small>

Empty spots in a class aren't just lost revenue—they're missed opportunities to build community.

The Scheduling Challenge

Every gym owner knows the frustration: some classes overflow with waitlists while others struggle to hit minimum attendance. The difference often isn't the class type—it's the timing, marketing, and booking mechanics.

Demand Analysis

Before adjusting your schedule, analyze what you have:

• Heat Maps: Which days/times see highest traffic?
• Class Fill Rates: Sort by % capacity filled, not absolute numbers
• Waitlist Frequency: Where is demand exceeding supply?
• No-Show Rates: Which classes have the biggest gap between bookings and attendance?

This data reveals whether you have a demand problem or a conversion problem.

Optimal Booking Windows

Booking windows dramatically affect fill rates:

• Too Early (14+ days): Members forget, plans change, no-shows spike
• Too Late (12-24 hours): Feels like afterthought, impulse bookings
• Sweet Spot (2-7 days): Enough time to plan, close enough to commit

Consider opening additional spots 24 hours before class to capture last-minute demand.

Waitlist Mechanics

A well-designed waitlist:

• Auto-Promotes: When someone cancels, the first waitlisted member gets notified and auto-booked
• Shows Position: Members see their place in line
• Time Limits: Released spots expire after 2 hours if not confirmed
• Fair Queuing: First-come, first-served with clear rules

No-Show Management

No-shows kill class dynamics and waste instructor time. Strategies that work:

• Cancellation Deadlines: 4-12 hours before class
• Strike Policies: After 3 no-shows, booking privileges restricted
• Deposits: Require credit card on file, charge for late cancellations
• Positive Reinforcement: Reward consistent attendees with priority booking

Balance enforcement with flexibility—life happens, and overly punitive policies drive members away.

Instructor Optimization

Your instructors are your biggest cost and biggest asset. Optimize by:

• Cross-Training: Instructors who can teach multiple formats fill gaps
• Performance Tracking: Fill rates by instructor reveal stars and struggles
• Schedule Preferences: Happy instructors deliver better classes
• Substitution Network: Build a bench of reliable subs

Dynamic Scheduling

Don't set it and forget it. Review your schedule quarterly:

• Cut classes consistently below 50% capacity
• Add sessions where waitlists form regularly
• Test new formats in low-competition timeslots
• Seasonal adjustments (summer, holidays, new year)

The Technology Factor

Modern scheduling software should:

• Send automatic reminders (24h, 2h before class)
• Allow instant booking from mobile
• Sync with member calendars
• Provide instructor dashboards
• Generate actionable reports

The best schedule is one that evolves with your members' needs.
