i know that you are working on thai pads but are you doing any kind of straight cardio? treadmill, jogging, jump rope? when i was training last year the tread mill worked great for cardio. my last MMA tournament i wasn't even winded after my fight, breathing wasn't heavy or anything. plus besides your classes are you doing any weight training daily besides the few that you blogged? otherwise i can give you some ideas to spice up your training. on the ill days try a quick jog. sometimes things just need to get moving before you can get anything done. also astragulus and ginseng are really good for keeping your endurance energy and immune system up.
