I suffered a heart attack right after Brazilian Jiu-Jitsu training last year, and as a result I have been paying much more attention to my health.
I've trained in martial arts on and off for years, but now that I've been through rehabilitation, and talking to various health and fitness professionals (Osteos, Dieticians, Physios, Personal Trainer, etc) it has become clear to me how little I have been taught about basic fitness as part of my martial arts training. I'm convinced that many (but certainly not all) warm-up routines are just some exercises the instructor learned somewhere and threw together.
Sure I could (and probably should) have gone out and taught myself about these things, but I'm curious how many martial arts schools, or instructors, have fitness qualifications, and use that as part of their normal training?
I'm not aware of any requirement for being a fitness instructor when you start teaching martial arts. Do many people do this of their own initiative or see value in it?
