| Strength and free weights | About 50 sq ft (4.6 m²) per selectorized station; roughly 65 sq ft (6 m²) per free-weight station | Bench and rack use, plate loading, spotting, maintenance, impact flooring, and a route that does not cross lifting zones |
| Cardio | About 50 sq ft (4.6 m²) per machine before confirming the manufacturer's operating and dismount clearances | Safe approach and exit, cleaning access, power and data, staff sightlines, and clear space at accessible equipment |
| Group exercise studio | About 50 sq ft (4.6 m²) per participant for an early class capacity check | Instructor zone, movement envelope, equipment storage, door swings, acoustic separation, and an unobstructed exit |
| Locker and changing rooms | Start with 8 sq ft (0.74 m²) per full-height floor locker, then add about 50% for internal circulation before showers and toilets | Dry and wet movement, benches, privacy, accessible changing, plumbing walls, ventilation, and a route outside training areas |
| Reception and entry control | Size from peak arrivals rather than membership totals; keep at least a 36 in (915 mm) accessible route and a 60 in (1,525 mm) turning space where required | Check-in queue, gate swing, staff workspace, visitor waiting, and a direct view of the entrance and main training floor |
