UFC fighters train very similar to wrestlers and other grapplers. The weight control methods used and the floor exercises (push-ups, sit ups, pull ups etc.) This is mainly because its just convenient...when training to pop out a few reps of each. Most fighters and grapplers will train with weights later on in the day or at night...but not during their "sparring" or "grappling" sessions....running and other cardio regimes are done, but not as much as you would think.....the best way to get in wrestling, grappling and boxing shape is to box, wrestle and scrap....simply put.
