Re: Adding the ability to hit with power
I'm not sure I can disagree with the quote more.
Power is defined as the rate at which work is performed or energy is converted.* This means that more efficient execution of a swing or a pitch or etc. can result in more power output.
Knock on wood a few times, my older son has an .800 batting average right now in a very tough and competitive league and he is considered a "power hitter". I teach him and he practices hitting based on Jack's work where everyone else in the league is taught linear hitting. He is not yet "perfect" in Jack's technique but we are working hard on it and that imperfection in a way is a very good thing because he has even more room for improvement - increasing power and more consistent output. My younger son hit two in the outfield Friday night and he was using Jack's technique to do it. I wish I had a picture of him at contact to show, but he clearly had those tell-tale signs of rotational hitting in both swings - very different from all the others.
Regarding pitching, my son recently changed his pitching arm path and picked up about 3 to 5 mph on his pitching velocity and if he goes back to his old pitching arm path he loses that speed. In the new arm path he has also gained accuracy and consistency.
With all of the less than perfect instruction out there, there is no surprise that such a quote would surface. By the way, Jack addressed this in a batspeed.com introduction web page.
