Check out this youtube video on judo with some cute little twins and a wicked tani otoshi or two. Is that Ken Otto in the video?
This really nice video talks about all of the good in judo. I've been doing what I want to do in judo lately. Teaching people across a wide age range at the Gracie-Barra Corona Judo club Grand Opening.
Julia finally got her way and we did a whole practice of just judo games. Here is one below that develops both grip strength, since you have to pick up a really heavy person by their judo gi, and upper body strength as you carry the "dead man". It is a race around the mat, with the first team to carry their body all the way around winning. If you don't have the advantage of really heavy people, you can have each person in the group carried one at a time around the mat, like a relay race. In addition to building strength and teamwork, this is fun, as you can see from the winning team in the back of this picture celebrating their win.
By the way, I stole this idea from James Wall of Wall to Wall Martial Arts.
