I spar at different clubs all the time only to see too many martial artists that cannot plant their feet properly and hit hard.  I’ve seen 5th Degree Black Belts who have trained for 20 years hit with less force than someone who has boxed for a couple of years.

I believe it should be a core skill for any martial artist and Instructor to pass onto his students.  After you watch the video see Lance Lewis’s program – Click Here
