Learn martial arts. When you're first trying to get into MMA, it'll help if you've got some experience (even at the beginner level) with basic mat wrestling and some variety of martial art. You can jump right in and start learning MMA basics, but being a well-rounded fighter who's able to take the fight to the ground as well as out-box your opponent is the difference between being a great fighter and a mediocre one. The best martial arts to familiarize yourself with for MMA include:
Marsden also adds that this type of bodyweight circuit is inherently flexible, so feel free to mix up the exercises as you wish. He just has one word of caution: "Feel free to change up the movements, but be cognizant of varying the exercises to maximize heart rate changes," he says. "By this I mean don't do three high-intensity movements before ending with two rounds of lower-intensity planks and flutter kicks." Rather, switch back and forth between higher- and lower-intensity exercises when planning your bodyweight circuit.
The first thing you should always do is start your MMA workout with some shadow boxing. This is done best in front of a mirror so that you can see your style of striking and the improvements you need to make while striking. If you’re new to shadow boxing, a good rule of thumb is to always finish your punching combinations with knees or kicks. If you’re a boxer then don’t worry about knees or kicks, just work on your punching combinations and your flow. Visualize the opponent in front of you and moved to create angles that could be used in a real life situation. Don’t be stagnant with your movement, allow yourself to be comfortable so that you can become more confident with your flow.
The truth is this: if you really put your mind to it, went back to school and graduated with an honors degree in exercise science, trained dozens of fighters in person and hundreds of fighters around the world while receiving feedback and tweaking the program to make it better and better, in about 10 years or so you could probably develop, perhaps, an equally effective strength and conditioning program for MMA yourself, just like I did with the Ultimate MM Strength and Conditioning Program.
