One who spends entirely too much time partaking in muscle building, strength training, cardiovascular, or aerobic activity. Specifically, one who does so at a health club or gym.
Often used derrogatorily by people who do not partake in or understand this lifestyle, some self-proclaimed gym rats use the term as a status symbol or for positive reinforcement.
Rare: The term is sometimes used with homosexual or dim-witted connotations, but both are entirely unfounded (the author of this definition is a gym rat, and does not fit these connotations).
I prefer to work out at home... I don't need to hang around a bunch of gym rats.
Look at those gym rats! They can name all their muscles, but I bet they couldn't tell you what an adjective is!
