naivegrl, you're not the only one who's lost a whole lot of weight from kickboxing! This is actually my second time around losing weight. I've been huge my entire life and in 2001 or 2002 I had reached 245 pounds and had never worked out before. I tried out a local kickboxing class and loved it so much that I signed up and did it until about 2003. In that time I had lost a total of 67 pounds! I had fun doing it too! I was so strong and with 1 roundhouse kick I could topple the bags we were using right over! Then I went back to school and stopped going and I really miss it. I'm keeping the hope alive that one day I shall return!
