I concentrate solely on ninjutsu right now, so much of my time not spent with friends practicing techniques is spent training in movement and the like (i.e. rolling, leaping, kamae flow drills, phantom steps, etc.). As for actual workouts themselves, right now I don't do much as I'm giving my body a little bit of a break but I currently do plenty of stretching and calisthenics, the occasional kettlebell workout, lots of tree climbing and running, the Air Alert 3 program (a nice little program to make you jump a lot higher, so far it's working dramatically well), and occasionally I'll do some tricking just to have some fun and do my wallflips and aerials and tornado kicks
