It was last week, I myself broke 120 12"x12" boards and raised $240. All together we raised about $5700 for a local charity called Warm-the-children. Which gives new winter jackets, gloves, hats etc. to needy low income area children. We get donated wood from home Depot, Lowe's etc.
Breaking is all technique, if you do it wrong you bleed and usually hurt yourself.
I train in old-school moo duk Kwan TKD. I'm a preliminary Blackbelt. Kinda like a mesh of Shotokan karate and kickboxing. We do forms, self defense, takedowns, groundwork, one-step, basic kicks (side, spinning, wheel, axe, hook, front snap etc) flying kicks, punching (boxing & traditional TKD hand techniques) and medium contact sparring.
Definitely keeps me in shape, otherwise I'd be a skinny/fat gut guy lolol.
