All right, so I'm going to ask you what you're doing when you're standing on one foot. I know you already talked about your back injuries. I know it increases the burden hitting you from standing on one foot. >> No. >> All right, so hold that position while I go through the instructions. You're going to lift one foot up in the front of you, your left your right, that's up to you. You're going to hold it until I tell you to stop. While you're holding you're going to count out loud in thousands, 1 1,000, 2 1,000, and so on until I say stop. You okay? All right, so I'm going to demonstrate it for you. While you're doing it you are going to stare down at your foot. So do you want to watch me do it? So I'm going to stand just like this. 1 1,000, 2 1,000, 3 1,000, 4 1,000, 5 1,000. Just like that with my foot parallel to the ground. You think you want to try that? All right. So when I say start you're going to do that for me, all right? Make sure you keep your hands at your side, lift one foot off the ground about 6 in while you're standing down at your foot. Do you have any questions? All right. Ready and don't forget to count by thousands, all right? And start.
