I compete in bjj a lot, and teach as well. I used to be a competitive gymnast, but have since lost all my flexibility. Have started stretching again and should get it all back within a few weeks (took 6 weeks to be able to do the splits last time i restarted a few years ago) I also do use rubber guard a lot, personally I like it, so I do a lot of stretching for knee and hip flexiblity. But i want to get into yoga. Its all well and good being flexible, but you have to be strong in this wide range of motion as well. Im wanting to get into yoga that is strength based. Anyone know anything about yoga for strength ?
