Hey, I want to start learning martial arts, and i have picked a few that i want to combine: Judo, Muay Thai and jeet kune do. Unfortunately i cant train them yet, since i am studying full-time at the moment. I am not very flexible, and i was wondering if it would be a good idea to do some stretching routines. So that when i am ready to start learning these martial arts, my flexibility wont hinder me doing so. If so, are there any stretching routines that you can recommend? And is there some pitfalls that i should be looking out for when it comes to stretching? Also i have been looking at some of fightTips's stretching videos are these good?
