In the fall I'm transferring to Central Michigan University to complete my Public Relations major. I've worked with my younger brother for the past 6 years, mainly just building a base of mechanics. He made JV as a freshman this spring. He's a big kid, 6'2", 185 pounds (he turns 15 in a month). Without really any weight training or velocity training he throws about 80 mph. We've just started long tossing for max distance this spring, he hits about 270 feet. He has both some positives and negatives with his mechanics. He has a rather efficient arm action in my opinion and maintains the qualities you look for in "connection". A big negative is being front-leg dominant which in turn leads to some disconnections up the chain.
With me gone next fall, I want to leave him with a guide to continue getting better without me being there. It's time for him to get more aggressive with everything he does. The word I'm using is adaption.
Mechanically, a lot of correction gets made with his direction/alignment, rhythm, lower half use and posture. What I've realized is, a lot of this would clean up if he sped up his tempo from the peak of his leg lift to landing. That takes mobility, stability and quick-twitch muscles.
When it comes to velocity training, I want to implement progressive overload concepts. Baseball myth got the best of me for a while and a part of me was always a little reluctant to throw weighted balls. A lot of questions and reading up on case studies and research on the topic sold me on the concept. Arm efficiency (improving arm path/pattern/remapping), endurance, strength (posterior shoulder and pronator-flexor mass), arm speed and intent. Wrist weights as well.
What I'm doing is building a beast. I'm wanting to take a kid who was blessed with some natural size and arm talent and turn him into something. So what this forum will be updated time to time through the summer. I'll ask questions on weighted balls, wrist weights, programming in vs. off season, core stability, baseball specific training, strength training methods, ATP/quick-twitch muscle building, recovery, etc... I'm a sponge. Anything you give me will be processed and appreciated. Thanks guys.
