I tried Aikido last night. It is a nice change from Tae Kwon Do. Since TKD won't be starting up agian until June 6th I need something to keep active. Aikido seem less active than TKD, but you still sweat which is what I need. I was thrown at least 20 times last night. Aikido is all about holds, locks and throws. TKD is about kicking. They complement each other and give me more option in my martial arts training.
