Body treats cardio as strength-training?

Tkwild

I've done a lot of cardio over the years, as a skinny chick and a fat chick, and my body has always built muscle insanely fast rather than burning fat. Does anyone else have this problem, and have you figured out why? I have PCOS, I wonder if it's related to that.

I've never heard of that, but then again I don't know much about PCOS. Perhaps it has something to do with your PCOS treatment?

There's not really a treatment apart from low-carb, and these horrible pills that didn't help and upset my stomach.
