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 Massachusetts, gym and health club contracts are regulated under the Massachusetts Health Club Law (M.G.L. c. 93, § 80 et seq.). This law provides consumers with certain protections and imposes specific requirements on health clubs. For instance, contracts cannot exceed 36 months in duration and must allow for cancellation under certain conditions, such as moving more than 25 miles away from the facility or upon a doctor's order due to a physical disability. Additionally, the law mandates a three-day right to cancel after signing a health club contract. If a gym or health club contract in Massachusetts fails to comply with these statutory requirements, it may be considered void and unenforceable. However, if the contract is properly executed and does not contain any provisions that are unconscionable or prohibited by law, it is generally enforceable. Consumers who believe their rights have been violated can file a complaint with the Massachusetts Attorney General's Office.
