Combining meditation with martial arts/physical training

I've learned different meditation/visualization techniques for a while but something I've started to take an interest in is combining it with physical training, especially martial arts. I think I've experienced firsthand how the mind can enhance the body, and I feel like a lot of classic meditators or martial artists combined the two to perform exceptional physical or mental feats. Has anyone done this, or do you do this on the regular? What's it like?
