Fat person trying to lose weight– Is Marino non-judgmental?

I lost a lot of weight so far using Planet Fitness in downtown. I really loved the layout, it being small yet not super small (unlike the back bay location), and I liked the vibes and people. I want to save money by using Marino for free, but I cant lie, I'm scared of all the gym bros being there. Is Marino a safe, non-judgmental community for beginners to use the gym? In my high school gym, there was a lot of judgement, so I'm kind of wary knowing my classmates are going to see me at my most vulnerable moments (aka slugging myself onto the treadmill with a tomato face, barely breathing).
