Originally posted by LKH: Go to a physical therapist and buy some of the rubber band type (about 5" wide) material they use for therapy. You can get it in various strengths. Buy about 5 feet of whatever strengths you want.Take it home, tie a knot in one end and a small loop in the other. Put the know in a door where the hinges are and close the door.You can adjust the resistance merely by moving further out. I've never had one break, but I hold my hand over my eyes when pulling to my face.
