In martial arts, what is more important to train for? Endurance or Power?

I traim MMA in both catagories. U don't have to lift weights to make yourself strong for fighting. I'm not saying don't use them but I lean more in using dumbells but I do pushups crunchs pullup and such. It is much more important to develop core muscles so that they work in sync. Once u have that down then hit the weights. U don't use weights to increase endurance in the ring. U need to do circuit training with the kind of excercise above. And u need to run your *** off. Both long distance and speed running. Also strength doesn't mean speed at all. Speed is speed and strength is strength. They play together and assist each other but they are separate amd trained seperatly. Do u have a trainer? If not get one lomg enough to teach u the basics of body development for fighting.
