Some training, not sure the Judo name for the first throws but it is a combination whereby they block out your O-Goshi attack by placing the knee in front of your hip turn for their own uki goshi or some such, you proceed to step around then throw backwards across the chest. The guys in the vid range from Brown to yellow belts in Judo, the first two with the better back arches are the more experienced guys obviously.
If anyone knows the Judo name I'd like to know please.
This works gi or no-gi, methinks this type of throw has a lot of utility under the new rules whereby they can't stuff your step around with a leg grab.
Cheers
