Check out this nice post on "Jiu Jiu" Julia's BJJ blog To the fat person googling jiu jitsu Julia was heavier than 200 pounds and had zero athletic background when she started BJJ in 2010, at the age of 33. Now she's a 4-stripe blue belt and on her way to 135 pounds. It's amazing the personal transformations that BJJ has inspired. We all like to debate fighting effectiveness and state of the sport and who is winning what and so on. But I truly think one of the best things about BJJ is its positive influence on people's lifestyles.
