I would agree with Mr. Yeti here. Your first concern would be to get out of that situation. The only bright side of this is that you do
The "Upa" or Bridge Escape
This is the basic bridge escape from the bottom. This is also what all your other options will be built off of. This is your first go to move; as if it is thwarted you should be able to create a little wiggle room to go to the other options that will be listed below. Here's the Upa in steps:
1) Choose a side that you will bridge to. This will determine what direction you will bridge to, and what side of your opponent you will try to control. For illustration purposes, we'll say you’re going to bridge to your right (but this can be done-and should be drilled-off of your left side also).
2) Take control of your opponent’s left arm by securing your right hand on his left triceps, and your left hand on his left wrist. You can do this by also securing both his arms by grabbing at both his wrists, but the 2-on-1 control is a lot better.
3) Move your right foot up and outside your opponent’s left foot, blocking his left leg high and tight to yours. While you do this, bring your left foot up to your buttocks (you will be using your left leg as the primary leg to push off of, and if it is stretched away from your body and flat on floor it will have no power). When you are at this point, you will have isolated any movement on his left side which allows the sweep to happen.
4) Drag his left arm across and down your body. When you do this, gravity will work in you favor and bring his left side down toward the floor toward his shoulder.
5) While you are dragging your opponent’s arm across your body, bridge up hard using your left leg. You want to execute a full, explosive bridge from your toes all the way up to the top of your head. Also you do not want to just bridge up, neither do you want to just bridge up and turn to your right. What you want to do is bridge up and over your own right shoulder.
6) This should get your opponent rolling off of you over his own left shoulder. Continue over with the momentum until you end up on top in your opponent’s guard. Congratulations—you are now out of your opponent’s mount!
A few things to keep in mind:
- First and foremost: DO NOT PANIC. Yeah, being caught in the mount sucks. However, if you panic and start flailing and twisting and turning, not only are you burning yourself out, but you are also making yourself bait for all sorts of nasty submission holds. So keep calm and thinking. Remember that you have options to get out.
- Do not just bridge up and directly to your right. If you do that, your opponent can stop the Upa by wiggling his left leg free and posting it out. I will post later on what to do if he does that, but I digress… You want to bridge out at a 45 degree angle over your right shoulder. Think of it this way: If you were laying down on a clock face with your head at 12 and your feet at 6, you will be bridging more in the direction of 10 or 11 o’clock. This way if your opponent still posts out their leg, you still have the chance of pulling them over because they can’t use their arm to stop the roll and the direction of the roll is actually going away from their leg.
- When you complete the roll, post your arms out and establish a base. If you don’t, your opponent can continue rolling with the momentum you’ve created and end up right on top of you. This time, not only are you mounted, but you’ve just spent a lot of energy trying to get out, only to fail.
I'll address the Elbow escape (from which all your sobmission options will start) a little later. But I think this will help.
