Thanks for humoring me. I completely misunderstood that post when I skimmed it at first. That makes a lot of sense.
Nice write up. I think another common error is letting tori's right hand/arm straighten out as he is turning into the throw. That ends up pushing uke off tori's chest as much as the head bobble and it pretty much places tori's shoulder in an absolutely ineffective position for completing the throw. Keeping the right arm bent will also help uke from creating that space that he would use to block the throw. As always, nice post J_UK.
J_ UK, I' m sure you've mentioned before that it's important to keep the sweeping leg straight but on Inoue's uchimata DVD he always throws with a bent leg. Is this something he gets away with because he's Inoue or a different variation? I also notice he mainly steps to the point of the triangle whereas Adams steps off to the outside which is how I was taught it. Which is better?
So I couldn't recommend a single source. If I could only recommend a few points to take away they would be; the triangle, tsurikomi and chest contact.
If you can get those three the rest will fall into place.
Sorry for necroing a thread and maybe you even covered this in your original post and I just didn't pick up on it.
Uchi Mata is actually one of the first takedowns ever taught to me, but to this day I can't seem to avoid landing on top of my opponent and being rolled through so I end up on bottom. I notice that in Judo competition this seems to be completely normal but it's a non issue because the match is over at that point.
Is there a trick to making sure you can land in a solid side control every time?
