i found using a dumbell...u can increase ure rotary cuff muscles by slowing doing the pitching motion with the dumbell in ure pitching arm hand...this will help as long as u dont over due it...any one agree disagree or have any other things b sides longtoss



also how can u practice throwign faster without a partner

Sean,
Before you end your baseball career before it even has a chance to get started, SLOW DOWN. In your other post you said that you have just turned 13 and that you are an avid baseball player and this is your true love. It will not be for long if you go at it the way it sounds right now. First of all learn all that you can about playing the game the right way. So far you have mentioned dumbbells and long toss. The way you described the DB's is not how you want to use them. Increasing your velocity is not your main priority right now. Your overall mechanics and knowledge of the game are.
Let's go back to the rotator cuff. First off there are four muscles involved that pretty much hold your shoulder together. I'll start with the Supraspinatus,it starts at the top of your shoulder blade and anchors by tendon at the head of the upper arm bone (humerus).It is responsible for moving the upper arm away from the midline of the body and stabilizes the head of the humerus in the shoulder socket. Next is the Infraspinatus,it starts around the middle to the lower part of the shoulder blade and also attaches at the head of the humerus, this draws the arm towards the center(midline) of the body. It also externally rotates the humerus.Third is the Teres Minor it attaches under the infraspinatus on the shoulder blade and attaches again at the head of humerus, this muscle also helps to move the humerus towards the midline of the body and also will externally rotate the same bone of the arm. It also helps to extend the arm. Last but not least of the four is the Subscapularis, it internally rotates the humerus and helps to extend the arm. It attaches to the underside of your shoulder blade and also attaches to the head of the humerus.
If you were to damage any of these muscles it would really hurt your shoulder movement. Talk with your P.E. teacher or coach and get back on the right track. The arm is not the only part of the body that you will use to throw. If you really love the game prove it by respecting yourself and taking care of your body. If you don't you will not be playing very much longer.

ok i didnt do it often just expereminting..i go to an academy for the mechanics which i agree are essential thanks for looking out for me

By the way, Hope your dream comes true. Good luck.

Hi Sean:


Your enthusiasm is compelling. To add to what Coach O told you; You are 13 so your medial epicondyle growth plate (inside of elbow) is wide open. Your lateral epicondyle is also wide open (thumb side of elbow). Your olecranon process is wide open (tip of elbow). You should learn the skills of pitching. Forget about the weights. Also, you (and everyone else) should never supinate (turn thumb up) the release of any pitch, including curvr balls.
