Used for escaping the mount.... (keep in mind I am by far not an expert on ground fighting)

Bridge with your hips and shoulders... after bringing your legs up and one just outside the leg at the direction you want to roll them to. Explosive move trying to catch them off balance.....As they are settling into mount position or shifting this position....

and?

I am weak on this one.... need some experienced BJJ or JJ guys to satisfy your and.

Ahh i see now, **** i got **** all expirence compared to BJJ on the ground. What part in particular you having problems with? I know as i do it, i remember, i got fucking creamed in the ribs, now it clicks every now and then. HAHAHAHHAHAHHA.

My problem is not having anyone to work with, I have no way of getting the FEEL of the technique....Its my understanding the UPA is based on timing... Catching a moment... Example, I saw the Vochanchin (sp) use it effectively in one of his fights caught the guy and rolled him... interesting.... I mean strikes and kicks you can work on the bag and get some benefit.... Some of the ground escapes you need a person to work with....

You should grab a part of you opponet before you attempt the upa, usually one of his legs and maybe even his belt if he has it, then you can control him as you fling him off you like a booger.

You got no training partners or anyting outside your Dojo?

Should find some in your area, and train train train

Ideally, you should trap (2 on 1) one of the attackers arm to your chest and upa to the same side. If you attempt an upa without some sort of control of the arm you will probably give up your back.

just my opinion

Thanks Kismasher good point....

I have this one bookmarked........and memorized.

The trick is also a lot to do with body positioning. You want him as close to your hips as possible. Second, you want to be subtle...I actually like to come across thier gi and trap, and have have the foot close, but not in the right plave till the last possible second.
Also, work on the elbow escape from there.

doesn't trying the upa escape help sometimes setup shrimping escapes because it causes him to open his legs for balance recovery?

greese1 referred to elbow escape, which is a shrimp escape

Thats what I meant... Doesn't a failed Upa help many times set up for this attempt.

Yes, because it creates room for you to move and disrupts your opponent's base.

One thing to keep in mind when you bridge is to not only go up, but also off to one side. I always seem to make that mistake.

Yes, the Upa (often called "bridging") and the elbow escape set each other up.

It works best if your opponent is on your hips, as someone else already mentioned. (Think of it like a lever and fulcrum.)

One of the keys that I found was that you should bridge up, THEN over, as opposed to bridging diagonally. This gets most of your opponents weight over your head and off of you, making it easier to turn him/her.
