Yvette Cormier, a member at the Midland location, says she had no idea what that meant until a few days ago.
"I was stunned and shocked. He looked like a man. He did not look like a woman," says Cormier. Cormier is talking about a person who walked into the woman's locker room while she was getting undressed. She says she couldn't believe her eyes.
"This is very unprofessional. This is very scary," continues Cormier. Cormier says she immediately complained to the front desk and eventually to corporate offices.
"They told me the same thing, that he was allowed in there because that's the sex he wants to be," says Cormier.
Cormier says she understands that some men self-identify as women and some women self-identify as men but says this person looked like a man and that caught her off guard.
Cormier lost her membership for violating the company's 'Judgement Free Zone' policy.
Moving forward, Cormier says she isn't concerned with getting back her membership. Her concern now is to warn other women at this gym to make them aware of this policy, because she says Planet Fitness failed to warn her.
The company told TV5 that Cormier's concerns about the policy regarding gender identity was inappropriate and disruptive by complaining to other members at the gym.
