Breaking Bricks - My Personal Best
In Universal Kempo Karate, we use brick-breaking as a way to test and hone our focus. Breaking a pile a bricks has very little practical benefit but it builds confidence and teaches you to hit with power and commitment. My personal best is a stack of 6. This was done in September, 2001 as a Brown Belt Step II.

The video of this is about 4MB. This may take a while to download but is pretty cool.
