Hi, I'm Cary Williams, and I'm going to be going over some shoulder plyometrics. Benefits obviously for the shoulders are for activities that you are doing when you are using your shoulders, so maybe you are in a rec sport, maybe you play basketball, maybe you play softball or maybe you do boxing, absolutely imperative for boxing, those shoulder plyometrics are going to really benefit your boxing skills. So for your shoulder plyometrics you can use a medicine ball, I have one here. You can use about six pounds, up to ten pounds, just depending on where your fitness level is at and what I do is I use a wall and I'll be getting in a squat position and I'll be facing that wall and I'll just basically be taking that ball to my chest and throwing that ball up, slamming it against the wall and catching it again and then be pushing the ball right back out. So that's the plyometric action is that you are pushing it, it's bouncing off the wall, coming right back to you and you can do alternate arms. So that way you are really working everything evenly because when you use two hands a lot of times you are going to favor one of your arms. So you're going to do left and the you're going to do right and alternate those shots. Well the other thing you can do without a wall is that you can just throw that ball over your head so you have your medicine ball and you're just tossing it overhead and catching it so it's going to work the top of the shoulders as well for your plyometric exercises.
