Also cardio is kinda like strength training in that there's a bunch of different types you can do. I can do running one week, get my body all fucked up and let it repair itself, then do intensive yoga the next week and have the same thing happen.

Hell by this ripping/repairing logic I could seriously do some hardcore stretching to burn some calories.
I doubt that repairing muscles really burns many calories compared to cardio ;/

fuck instead of waiting around for your body to repair itself, with cardio you could just run every day if you're in good enough shape. I'm sure that would burn more than letting your muscles repair.
