Blocking punches in Muay Thai
I've been going to a MT gym for several weeks now, and today we learned how to block straight punches and hooks. A straight punch is blocked by pressing your glove against your forehead, with your palm pointing at you. Hooks are blocked by pressing your glove against the side of your head, with your elbow pointing towards the opponent, and slightly inwards (or so).
I suppose these are fine in the context of MT, but they're suicide in a self-defense situation, where nobody is wearing big boxing gloves. I train for SD and not competitions, so that's kind of a big deal to me. I was thinking of learning some boxing next year, but I'm wondering what most instructors would think about someone incorporating boxing techniques into sparring. Is that generally accepted, or is there some reason why you shouldn't use boxing-style blocks and evasions in MT?
