From my limited knowledge foam rolling is like a poor mans Active Release Technique that breaks down scar tissues (hard knots in the muscle tissue). So I suddenly got the idea to self administer something similar, basically on the muscle groups I can reach (shoulders/chest/thighs/calf) I dig my fingers in and look for hard spots. I then use my thumbs or the first joint or even my knuckle to really dig into the spot. Sure as hell did it hurt, but afterward I felt great.
Is there a possible drawback to this? I think I might be oversimplifying ART and might be hurting myself. Any input?
