Very often people will ask me about the effects of body type on jiu jitsu. It appears that many people hold the belief that there is an optimum body type in jiu jitsu that confers advantage over other body types. Even a moments reflection will reveal that this is false. A look at the medal platform at the world championships will always show a wide variety of body types which are represented in no particular order of success. If I ask you to name for me the five most successful jiu jitsu champions of all time, I guarantee your list will show big disparities in body type. There is no dominant body type on the medal stands. There is however, a dominant body ETHOS. Champions always maximize the ability of whatever body they have been born with to perform the skills of the sport. Whilst there is no one body type that dominates the sport, there is a need on everyone's part to maximize what you can do with your body that will improve your jiu jitsu performance. Everyone's body has an optimal weight and conditioning that maximizes its performance for a given activity. It is your duty to find what that is for you and to maintain yourself close to that ideal (getting closer if competition is near). Thus any body type can win a world championship, but only one way of maintaining that body of yours will maximize your ability to perform the skills you hope to win that championship with. Here are three EBI champions. All three are very different somatotypes - Garry Tonon is a classic mesomorph. Gordon Ryan an ectomorph and Eddie Cummings an endomorph masquerading as a mesomorph. Yet all three have found a way to maximize their very different bodies to perform the skills they needed to win. Thus any body type can win a world championship, but only one way of maintaining it will maximize your chances of doing so. - John Danaher, Body type and BJJ.
