So I'm gonna try to keep this short. I've been breaking boards rebreakable ones at my dojang. Like 2 weeks ago I broke a green one(equivalent to a 1 in pine) I broke it pretty easy with my non dominant hand. So the other day I figured let's try the next difficulty up with my dominant hand same strike just different hand. I couldn't break it tried 3 times, I did break with an elbow but my right knife hand wouldn't break it. Is there any way I can gain some power on this strike at home? I don't have any punching bags or anything but was wondering if yall could give me some advice on this. Thanks.
