So, what I'm going to have you do is stand facing me. Turn here so I can see right there. All right. So, what you're going to do, do you have any leg back problems? Anything like that? Knee replacements, hip replacements, anything like that? No. >> Okay. So, do you need your glasses on? You can put them back on now. I'm done with your eyes. What I'm going to have you do is stand with your feet together like this. Hands down to your side. What you're going to do, whichever foot you choose, you can do either one. I don't care which. When I tell you to go, I'm going to have you raise your leg up approximately 6 in off the ground. You're going to keep your eyes on your toe, and you're going to count out 1,00 1,002 until I tell you to stop. Okay? >> All right. Give me one second.
