From what I've seen on using foam rollers there have been several techniques of using foam rollers/lacrosse balls and the first one I've seen is to put the muscle in a flexed position and then start using their foam roller/lacrosse ball. Along with this technique there is also the other variation of putting muscles in their relaxed length position and then start rolling. Finally another technique I've seen is putting the ball/foam roller over a certain area of the muscle, and then start flexing and extending the joint of where the muscle connects and causes it to move (ex. hamstrings-knee , quads-knee, triceps- elbow)
So I also want to ask, are there other ways/techniques in using self myofascial release, when applying a lacrosse ball/roller to an area?
