Hi Guys!, Me again, I have a question about getting lean and bodybuilding in conjunction with practicing Ninjutsu, I know stretching is paramount to maintaining body health and practicing some of the leaps and leaping rotations are good for cardio. I am aware that Hatsumi Sensei stretches every day and is limber and spry for his age.The general concensus in my class is that bodybuilding is degenerative and not practical for Ninjutsu, I'm not talking about getting huge as I'm 50, but I was trying for a more lean Bruce Lee type physique,I am a bodybuilding fan but as I have a torn bicep and rotator cuff tendonitis, I was wondering if my gym endeavors are counter productive to my Ninjutsu training? Opinions please
