This may seem to be the case with judo, but the opposite is actually true.
A self-defense curriculum should incorporate techniques that can be performed by the average person. Martial arts styles that are reserved for the physically talented offer little to the general public as a whole in terms of self-defense training. This may seem to be the case with judo, but the opposite is actually true. Walk into any judo dojo and you will find a variety of judokas, not just super athletic human specimens. You will find judokas from all walks of life, both men and women, young and old, and just about every body size and shape imaginable. Even those physically impaired participate in judo. In fact, of all the contact Olympic sports which include wrestling, judo, taekwando, and boxing, judo is the only combat sport included in the Paralympic games. After all, it is those in society who are at a higher risk to unsolicited attacks who are more in need self-defense training, not the physically gifted. Judo is a sport for anyone who wishes to participate in it, regardless of athletic ability, age or gender.
