Hi, I recently started BJJ training and i'm out of shape (5'10, 250lbs), recently quit smoking, and have asthma. During warmup in the class I normally cannot complete the entire thing, normally after about 5-10 minutes i have to stop the warmup and take a break while the class continues. I quit smoking a few months ago, am on medication for the asthma, and on a strict diet losing weight. Do you think me not being able to complete the warmup and having to take breaks is frowned upon by the rest of my class? It's a little discouraging. Should I stop going and come back once i've lost the weight and can finish the warmup? Or stick with it?
