In my Taekwondo classes we sometimes train throws, in the context of self defense (hoshinsul). I'm bothered that, when being thrown, I can see that the way in falling is not the best and I'm getting too much impact when hitting the mat (even if gym mats are used).
In fact, learning to fall when thrown is not something trained often in TKD classes. What kind of exercises I could do on my own, at home, to improve this?
