text: what is the base level of physical fitness required to start mixed martial arts training (bjj and muay thai)? i'm 29, 6'4", slim 200. i haven't hit the gym or even run a mile in 11 years. how many pushups should i be able to do? situps? running? when i reach "at least basic good shape" i will start training. what cardio prep do i need? you don't need to be at any specific level physical fitness to begin training. training in itself will work on your fitness and get you where you need to be to compete (if that's what you're looking for). you just need to find a good teacher who can work with you and help you reach your goals.  never be afraid to start a marital arts program just because you feel that you are not fit enough. one of the main points in training is that it will help you to become fit, and as you do your confidence will improve.
