Just started BJJ about a month ago. I dont have any kind of other martial arts or wrestling base so i find that my mobility on the mat is...well...terrible. For example, when i try bridge to shrimp to get out from under side mount, i'm not quick enough after the bridge to get a good shrimp in...if that makes sense. Anywho, can anyone point me to some good hip mobility/strength drills i can do at home? A friend i'm taking the class with found this set of drills last night on youtube and i figured i would start there. http://www.youtube.com/watch?v=iydZKc_mnn8 Thanks!
