I've been starting to research some open hand techniques for work. Truth is the agency I work for doesn't offer a whole lot of training in self defence or take down methods for liability reasons. So if you learn anything its from an outside source and on your own. So if anyone out here has any advise on some open hand striking and defensive techniques I would appreciate it. So you know, I am just about always on camera at work so an open hand is going to look a lot better in terms of defensive positioning rather than a closed fist. Also if you have any recommendations on training out side of a heavy bag on increasing the power and toughening up my palm strikes I'll take it. Thanks.
