okay so i used to be kind of comfortable in my vibrato technique and thought my only difficulty was speed. i go to that guitar principles website, there was a link somewhere in a UG post i read. and apparently the way i am 'comfortable' in doing it is the same way virtually everyone is onstantly doing it wrong, and so now i really want to learn how to do it correctly and their directions were pretty uclear to me.

can people give advice for proper good bending, vibrato, and really anything else that me and others are probably doing wrong and how to fix it?

much appreciated.
the second one is a cool idea i will definitely try, but im still confused as to the proper movements, like usingthe right muscles and whatnot. can anyone hook me up with help for those?
