Which begs the question — what was an NFL champion doing at Planet Fitness?
"So I have trained at well over 1,000 gyms all over the world. Not one time have I ever been approached and asked to 'tone it down.' Today I was unceremoniously kicked out of Planet Fitness for excessive breathing/grunting," Weatherford wrote in the caption of a video on his Instagram page.
Weatherford claimed that after he grunted, a siren went off. Planet Fitness is known for sounding a siren if someone is grunting too hard, or acting like a "lunk." They call it the lunk arm — and Weatherfound found it shameful.
"A gym should be a place that encourages, motivates and inspires you to build the best version of yourself possible," Weatherford said. "Not a place that has a built in siren the manager activates when someone is working hard and breathes heavily. I'm embarrassed to say I paid $20 to this establishment."
There are plenty of reasons to be embarrassed of Planet Fitness — the free pizza and bagels, for one — but the lunk alarm is what set Weatherford off.
