Hi, my name is Shane Freels, and I'm with livestrong.com. Today, we're going to cover joint deterioration in the knee. Now what does that mean? That means we just kind of have to cut out a couple things like plyometrics, we're not going to be jumping, we're not going to be putting a lot of weight on the individual. So let's think about how we can minimize the load and yet you still want to strengthen the quads, the glutes, the hamstrings that really give the full body the strength that it needs in the lower extremities. So one of the basic exercise that I like to do the most is what we call a stability ball wall squat, you want to put it in the small of your back so it doesn't need to be at the butt, it doesn't need to be way up in the middle of your back, it needs to be right in that lower lumbar curve, you have a lumbar curve that you're trying to set that ball in. Once it's there you want to make sure that your feet are stationed at about, just out in front of your knees, okay? I want to make sure that when I squat I'm pushing back into the ball, okay? So as I'm going down the ball is coming with me, I'm getting down to about 90 degrees, I'm not having any pressure on knees, I'm strengthening my quads, my glutes and my hamstrings and I'm pressing through my heals, okay? So I don't want the pressure to be on my toes, I want it to be on the back of my heals, good range of motion. Again my shoulders are always back, my chin is up, it's always good posture. You can do it with your hands to your side, you can do it with your hands out in front of you, which every way you want to do, we just want to make sure that you have good posture, good range of motion. If you do have any kind of joint discomfort while you're doing the exercise, make sure you stop at that point that you feel it, if that's your range of motion, that's where you work, okay? Again my name was Shane Freels and we just showed you several good exercises that you could do with joint deterioration in the knee. I hope you find then useful and make it a great day.
