Anybody with infants go to the gym and do classes?

So I’m extremely paranoid ab going back to the gym. I need to go. I’ve tried exercising at home and it’s terrible. I’ve never been able to finish and concentrate at doing an at home workout. I’m vaccinated but I know I can still catch covid but what if in the classes, in the midst of heavy breathing, I get it from someone and bring it home? I’m just scared ab my baby. I’m thinking I can wear a mask while running and doing burpees etc…but online it says it’s not recommended.

Any thoughts? Experiences?
