Crossfit is a good way to get in shape for MMA. Crossfit is a balanced full body workout that combines cardiovascular/respiratory endurance, stamina, strength, flexibility, power, speed, agility, balance, coordination, and accuracy. CrossFit athletes run, row, jump rope, climb rope and carry odd objects. They frequently move large loads quickly over long distances, and use powerlifting and Olympic weightlifting techniques. CrossFit athletes also use dumbbells, gymnastics rings, pull-up bars, kettlebells, and many bodyweight exercises. I believe crossfit is perfect for MMA because not only will you receive the great conditioning when using the program, but you will also save time so you can coordinate other aspects of training such as sparring in your routine. An average crossfit routine is around 10 to 15 minutes. If you want to learn more and view an example of a workout routine you can go to crossfit.com or crossfithardcore.com. Hope this helps. Good luck!
