To quote Gene Simmons: "I like money and I want more of it"
It is not like it is "evil" in the end it gives the parents a chance to dump their kids off for an hour or two. The kids get to hangout with friends, shoot the shit, run around. Nothing wrong with that kind of stuff.
Now, if the parent thinks this is how Timmy will end up with a full ride to a D1 school...well, they are going to be disappointed.
Does the cost = great results? Probably not.
Baseball camps by and large are a waste of time and money. When you have 20-30+ kids running around, how much actual individual instruction do they get? I developed a methodology a long time ago, and I've never charged a penny for it. Any dad with a decent background in baseball can do this.
I would have the dad videotape, even using a phone and have his son take 3 sets of 12 swings with 10 minutes between sets so you don't wear the kids' arms out. (How many times in their career are they gonna have at-bats with more than 12 pitches in an at-bat?) First set of 12, you film from directly in front of the kid, if you have a screen thats great, if not, don't use a ball, the target is the top of the tee anyhow.
After 12 swings and a 10 minute break move the video to 1/2 the distance between the front foot and the tee. The 3rd set is setting up the video 1/2 the distance between the tee and the back leg. That way, between the 3 sets you're able to see the swing in its entirety.
The first set allows you to check balance, where his eyes are, is there zero head movement, is there any type of pre-pitch rhythm, what is the direction of the bottom hand on the bat. For a right handed hitter, the knob of the bat should reach the left hip before the barrel begins to drop, that insures a short swing and backward spin on the ball which gives the ball carry.
The 2nd set allows for a check on the hip rotatiion, is the front half in unison with the hands moving back, is there a hitch or a dropping of the hands, etc. This will show if its an A to B to C swing, or the needed A to C swing.
The 3rd set will show the whole body in action, where does the knob of the bat go, straight back or is it moving upwards as it should to create a whip action, does the left/right arm (depending if he's a lefty or a righty hitter) open up too quickly which affects the speed of the swing. The left arm is for accelerating and the right arm for guidance. (The opposite for a left handed hitter).
You need to show these kids how to swing A to C because by the time they get to 17-18 years old, if its not, they're not gonna catch up to any upper 80's/low 90's fastballs.
When they text me those sets of swings, I can break it down frame by frame, so by the time I ever work with them in person, I already know what I'm looking at. When we start to make corrections we always start at the feet and move up.
I skipped all the when the pitchers lifts his front leg, when the pitcher separates because there's a slight discernment between the two depending on the age/ability level of hitter the kid is and how hard the pitcher is throwing and how quick he is to the plate. It all goes back to the pre-pitch rhythm that sets everything in motion. Its not that hard guys.
