Do you train in fighting now? If so what do you train? Are you looking for sport specific drills or overall strength/conditioning assistance work? Put a little more into the question and you probably get better answers. Jump rope, sprints, sit ups, shadow boxing, shadow wrestling, push ups, hindu squats, cleans, jerks, squats, romanian deadlifts, push presses, bear crawls, crab walks, lots of stretching, speed bag work, heavy bag work, focus mits. Oh yeah, and don't forget good old sparring.
