I could use some advice from all of you jiu jitsu brothas out there. I am really struggling when i am on my back and my opponent has side control. Basically, i need some tips on regaining the guard... when i roll with more advanced practitioners and inviduals with a real solid base i struggle to get out of this possition. when my opponent does things such as... blocking my hip with his hand on the ground to prevent me turning into him and at least getting butterfly, or ....takes his hand and weaves it thru my leg and holds the opposite knee to also prevent me from turning into him, or ... posts his foot on the ground and puts his knee into the back of my knee to also prevent me from turning in.... i really sruggle. I am pretty crafty when it comes to avoid submission, however being in this predicament causes me too be defensive the entire time... can anyone offer some advice?
