What do yall wear to workout?

Hey so I’m trying to work out more since starting T but I’m pre op and don’t know what to wear. Ik you’re not supposed to wear a binder and if I do then it’s harder to breathe. I don’t have sports bras cuz I’ve been out for years now and they make me dysphoric. I try going with nothing on under a shirt and hoodie but I sweat so much wearing a hoodie while working out. Any suggestions? Can I wear a binder that’s a size or two too big? Thx
