Hello, I'm new here. I am joining an MMA school in the summer. I been strength training for awhile and power type stuff. But I have no endurance at all, I can only do 15 burpees in a row before I quit and only 25 MAX. I want to be all around in shape ready to go this summer when I step into this school! I'm pretty strong, and very explosive. But 0 endurance! Where should I start?
