I've been researching alot of things lately on the shoulder over the last few years ever since I started getting problems. I've seen countless doctors, physiotherapists and chiropractors who had no idea how to properly fix my issues. It took me 4 years to finally find the proper doctor who assessed my issues and I believe that I am not the only one out there with this issue.

Many pitchers out there have horrible posture. I've started to pay more and more attention to this since I found out my issue. Alot of people have hunched over shoulders from working at the computer all day or just being slouched over. Many doctors recommend just strengthening the rhomboids and traps to help this but the main issue is the serratus anterior muscle being weakened.

In the video with Dylan Bundy doing the punching bag program, he is working the shoulder muscles and lats but the biggest muscle he is working is the serratus anterior muscle. This muscle is probably the biggest muscle when talking about the shoulder and throwing a ball. It helps raise the shoulder when throwing and leaves more room for the arm to properly glide through the shoulder girdle. When this muscle is weakened, it cannot pass through properly which thing causes impingement on the rotator cuff which can lead to tendinitis, inflammation, tears and in the long run more stress caused on the elbow because it is trying to compensate for the shoulder's weakness.

I feel that this is the biggest issue when it comes to pitcher's shoulders. I don't think enough trainers emphasis the training of this muscle and when pitchers continue to throw throughout the season, this muscle will wear down more and more leaving the arm at risk of injury.

You want to have your kids last longer and stay stronger? Start training this muscle.

I've gone through 4 years of pain because of not knowing how to properly fix my muscular imbalances and I will tell you, this is the biggest thing that needs to be corrected.

It's pretty crazy how people are not told about this from doctors more. I was just reading the article on Bundy right now and I do do the inverted W when I throw. I'm 20 right now and for the past 4 years I've been getting impingement and my right shoulder is hunched over pretty badly. Well not nearly as bad as it used to. Funny thing is is that I can still throw at the ball in the upper 80s to 90 right now. My doctor told me the same thing. When it's working properly, I will gain quite a few mph on my fastball which is pretty exciting. He put me on a rehab programbut I was so busy with work I just couldn't find the energy to do it. It also took me a long time to finally feel the serratus working and know it's proper function when pitching and lifting.

I've read alot of thing on the Scap Pushup and pushup itself for targeted this muscle when done properly. Any other good ones besides the clean and press? I have tons of potential but this has been stopping me for along time from reaching my peak. I have 3 above average pitches as it is. Very very good change up and a sharp curveball. I'm 5'10, 175 lbs

I have a video of my throwing last week vs an older team. Is it possible for me to send it to you and have you take a look at my mechanics? I would really really appreciate it.

I don't have that problem when doing the test. I saw a doctor in London which is one of the best sports physio places in Canada when it comes to shoulder issues and he told me it's a matter of my motor functions. I've been trying to hold my scapula back and down for so long that the down rotators became too strong so when I throw, they shoulder cannot pass through the acromion properly due to the smaller space, therefore causing the impingement. I definitely have seen improvement since I started doing the rehab exercises. I was slacking at them for awhile do to working 65+ hours a week while trying to still play ball and lift. At the start of the rehab, I still didn't understand how to properly do the serratus exercises and it wouldn't get sore but now I can fully feel it working so it's a good step in my mind.

He told me rhomboid and pec minor were strong. Lower, upper and serratus were weak and couldn't function properly when doing anything overhead.

Uploading videos of me now. Will be under Tyler Gauthier in the forum posted. If they aren't long enough, I will have my dad tape me this coming Friday during our National tournament.

I definitely think it is just a muscular weakness. When I was younger, I decided to be an idiot and go for a beach body look and only train chest and arms while neglecting the back. This, combined with over pitching, let to tendinitis and two almost surgeries which I was lucky to not have done. My right side is definitely worse than my left when it comes to the scapular positioning. My right side just doesn't feel as supported and it definitely shows in the video as you can see me constantly toying with it. It took me awhile to finally realize to get the serratus working, you need to squeeze the traps per se into holding it tight against the spine. When I do this, it feel much more supported and the muscles feel like they are being worked.

Do you think if this imbalance is corrected, will I gained mph on my fastball when the shoulder can properly rotate?
