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 Hawaii, gym and health club contracts are regulated under the Hawaii Revised Statutes. Specifically, Chapter 481B-13 outlines consumer protections related to health club contracts. These statutes limit the duration of health club contracts to no more than one year, and they must allow for cancellation under certain conditions, such as moving a specified distance away from the facility, death, or disability. Additionally, the law requires that the contract be written in clear and understandable language and that it includes a statement of the consumer's cancellation rights. If a gym or health club contract in Hawaii 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 prohibited by law, it is generally enforceable unless found to be unconscionable.
