I been doing Taekwondo since 2005 and will test for my 2nd degree in April 2012.I’m considering taking up Jui-Jitsu because I sparred a mma friend who used jui-jitsu to lock me on the ground. I couldn’t do anything to get out. The experience thrilled me to learn more about the art. As stated, I’m doing Taekwondo and love it and want to take up jui-jitsu as well. The issues are 1. Time management. Working retail,college,and Taekwondo keep me busy…2. Do you think it would corrupt my Taekwondo performance picking up another martial art?…any advice will go appreciated.
