Traditional methods of baseball training have been taught subjectively and have ignored what science and research tells us about the human body. My method of player development is to get a baseline of critical metrics such as pitching velocity or exit velocity from a hitter. From there I use video analysis and give a side by side comparison with professionals to give a visual representation of how to perform a technique correctly. With consistent practice and hard work, most players will see a 5-10 MPH increase in pitching and hitting velocities within 2 months!
