 Don't they all have like instructions like right there on them? Some of them do and some of them don't. And I think I don't even know what part of my body to put there and which way I'm supposed to face. Am I supposed to be lying down? I have a feeling somebody is going to come by and I'm like working on my arms. They say that's for your calves. I mean, I don't know what you're doing there. I don't even know how you got in that position.
