text: i do muay thai and tai chi for 6 months i was wondering if it is a good idea to do more martal arts aswell?   it never hurts to try new arts or styles.  however, i would pick own art and get a strong foundation so that you always have something to fall back on.  since muay thai is such great striking art i would suggest you try taking some aikido, jiu-jitsu,  or judo to supplement your tai-chi training.  these arts, especially aikido, will help you better grasp the concepts and applications of tai chi. good luck
