first barry’s class as a solidcore girly in remission from cancer

Hey guys i’m F22 in ATL. So, I’m about 100 solidcore classes in and I go almost every day. I’m not worried about the strength training aspect of Barry’s but scared asf for cardio. As you can tell by the title, I’m in remission from chronic health issues, but getting a lot stronger and have been cleared by a doctor. I also have asthma so that worries me a bit too. I don’t want to look like a chud so wondering if I should do DF first or if I should commit to the bit and at least try the treadmill
