Can someone give me some advice please. I used to take Ishin Ryu Karate when I was about 12 years old. Right now I am 29, decent shape, I work out with weights 4 to 5 times a week. Cardio about 6 days a week. I am looking to take some form of Martial Arts again. I want to take a style where I can go into tournaments again(obviously with people at my same level.) Any suggestions? I would like a fast moving style. Please help. Thanks!!!
