This varies a lot within my system. The most basic forms are very short grappling forms (a set-up, a transition, and a finish). Those are practiced always on both sides, so there's no "other side" to practice on those.Mr. Skribs -
Interesting question to start a thread, and even more interesting to read the responses. It seems the various responders all train (or, at least their forms do it) by working to one side. In the MA system I train in, ALL forms/katas/hyungs have mirrored movements within them. If a form has 30 moves, then 15 of them will be to the left and 15 will be to the right. Not necessarily all 15 to the left and THEN all 15 to the right, but interspersed throughout the form. It would seem that the goal is to develop "muscle memory" so that our physical response would be more automatic no matter from which direction the attack came. We also train in Muy Thai and boxing as added training, and it is within those that I seem to notice that the focus is on the right side, with very little mirroring (if any at all). I would think that if a martial artist couldn't adapt to a "southpaw" confrontation vs a "normal" one, then they would be greatly hampered in their abilities.
