Despite what Austin Powers(TM) may say about it, there is no such thing as the famed 'judo-chop!
At least not in competition. Sorry if that disappoints you :)
Judo is a contact sport derived from the Samurai martial art of Ju-Jitsu.
To win a contest, a competitor must throw his opponent to his back, gain submission from arm-lock or strangle, or pin his opponent to the ground for twenty seconds.
Sounds a bit violent? Not dangerously so!
Serious injuries are not common but you can't expect to train without getting a few bruises
I practice in Sheffield, coaching and a bit of randori at the university club.
