I took TaeKwanDo classes for 3 years, made it to blue belt, 2 rep tips. I wish i woulda stayed with it, I'd be a blackbelt 5th dan by now.
Edit: To Jester- Technique always beats strength and speed. I reccomend you read a book called, The Tao of Jeet Kune Do. This book was written by Bruce Lee. If you accualy sit down and read it, you will learn a thing or two. But if you are to read it dont misunderstand it because the martial arts arent to be used in a stupid manner, (Didnt mean to be so crude there.) and takes an unorthadox amount of concentration and dedication to master.
