Thinking about seeing a few clients in my home gym. I have contacted many insurance companies and they will not allow an in-home fitness business on their homeowners policies. I asked another local trainer I know and she does not have her business on her insurance. This is not a chance I want to take.
I agree with all that Stephen and Karin say here. I also have a studio in my home. Between incorporating (actually I have an LLC), tightly written “waiver forms,” liability insurance coverage (both for your studio and for you), and good practices, you should be covered. I would NEVER go uncovered in this litigious society. Also, I think it’s good business to talk to an insurance agent that you trust, and let them know your plans, and lastly speak with an experienced business attorney (it’s worth the 1-hour consultation fee).
I hope this helps.
