Gym and health club contracts are notoriously stringent and difficult to break, and have often been the subject of class action lawsuits and other litigation. But like other properly-executed contracts, gym and health club contracts are generally enforceable unless they are unconscionable as a matter of law (this is rare) or include provisions that are prohibited by law. Most states have specific laws (statutes) that limit the terms that may be included in gym and health club contracts—and if such a contract does not comply with the state’s laws, it is likely void and unenforceable—at least in part.

In Florida, gym and health club contracts are regulated under the Florida Health Studio Act. This Act requires health studios, which include gyms and health clubs, to register with the Florida Department of Agriculture and Consumer Services. The Act sets forth specific provisions that must be included in the contracts, such as a buyer's right to cancel the contract within three days after signing it, excluding Sundays and holidays, and additional rights to cancel under certain conditions, such as relocation or illness. Contracts cannot exceed 36 months in duration and must provide for a refund if the facility closes and fails to provide an alternative location within five driving miles. If a gym or health club contract does not comply with these statutory requirements, it may be considered void and unenforceable. However, if the contract is properly executed and complies with the law, it is generally enforceable unless it is found to be unconscionable, which is a high threshold to meet.
