I can bend single notes easily, but how do you do chord like bedning? For example, how would I do a full bend on the 4th fret of the 2nd string and 6th fret on the 3rd string? Normally when I bend I use my full wrist this doesn't seem possible with what I'm trying to do. Am I bending right?
So its only 2 strings? Just push (or pull) with each of the fretting fingers. Try not to move your wrist, just your fingers.

Bend with a finger besides your 1st and use the other fingers to help pull the string.

EDIT: Sorry I didn't read your post. Just practice
