Why would you use it at a gym? You are more likely to get hurt as you are not paying attention. It's incredibly stupid and insanely rude.Is it true that you're not allowed to use a cell phone at planet fitness?
I sneak my cell phone occasionally, but they are prohibited at the Planet Fitness centers. Why? I think they may interfere with the machines but that's only a guess. Also, people may hurt themselves if they get too distracted.
No, I know someone who goes there. They use their cell phone there sometimes.
