Ok, here's my problem. My upper arms are all jiggly when I hold them out to the sides - quite unappealing. When I diet and exercise, they just stay there. Any tips on how to tone the underside of your upper arm? I don't know the technical name for it . . . when I hold my arms out to the side, palms facing forward, the problem spot is on the bottom . . . I'm just going to assume that I'm making sense and someone knows what I'm talking about . . .
