Any gyms that will allow me to keep baby near me?

I’m not looking for a gym with a childcare area, I’m looking for one that allows me to keep my baby on me or next to me. I saw a video of a woman wearing her baby to workout and was wondering if anyone has found gyms that allow this or just him to hang out in a stroller/car seat. I’m located in salt lake county for reference, but if you know of any gyms anywhere in the country, that would give me a starting point of where to look. Thanks!!
