Startup costs are typically around $500 to $3,000, depending on gym rental, equipment, insurance and marketing. These are estimates, so confirm local gym rates and requirements before you plan your schedule.

Monthly revenue is typically around $800 to $4,000, depending on sign-ups, pricing and how many clinics you run. Gym rental costs and cancellations can cut into margins if sign-ups are low. You can start with about 8 hours a week.

Check general liability insurance, which most facilities require, plus accident coverage for participants. Also check waivers, background checks, youth-protection rules, your city or county business license, state sales tax rules, and how to classify any assistant coaches.
