This has to be one of the biggest frustration in Brazilian Jiu Jitsu!
You smack, bump, and get ready to roll...Then you use crazy amounts of energy to pass your partners guard!! Then mount them...
What happens next?
Two seconds later he is back to guard, or he just simply throws you off and you are now EXHAUSTED!!
Even Worse, you get mounted by a bigger and stronger opponent and he feels so heavy that you can barely breathe!! and you feel helpless like there is no way out!
There is no greater frustration then feeling controlled and dominated in BJJ!
