These are ideas, not a program. I wrapped each clip so you know what to look for. If the video uses a cage or a fancy board, the note underneath is how you do it in the grass for nothing.
Happy Gilmore
You’re looking for the back leg to load and the hips to go. The step-in is just a way to feel that without a lecture. If it turns into a 40-minute clinic, you lost the point.
In the yard. Tee, net, a couple of feet of grass behind the plate. He steps in and lets it go. No specialized board. No walk-up music.
Tee — up the middle
The simplest round. Ball even. Drive it up the middle. You’re watching whether the barrel stays through the ball or he chops at it. No big coaching points.
In the yard. Tee into a net in the garage or the yard. If they are swinging metal in the clip, use wood at home. If you don’t have a tee, firm toss from the side works the same direction.
Tee — opposite-middle
We want a path that gets on plane early and stays there. Watch how he lets the ball travel and drives it over the opposite middle infielder’s head — not a roll-over to the pull side.
In the yard. Move the tee so the ball is centered on his body. Same net. Same eight swings. If every ball is pull-side, the tee is too far forward.
Tee — opposite corner
Ball on his back leg. He’s learning to stay through a pitch he used to swing around. Drive it over the opposite-field corner’s head.
In the yard. Slide the tee back toward his back foot. Garage net is enough. Don’t turn it into a physics class.
Tee — back at the pitcher
Hit the ball right back at the pitcher’s head. Stay through it. This is the round that tells you if he’s cutting off or actually finishing.
In the yard. Tee in the middle of the plate, net straight ahead. College clips will show metal. Use wood in the yard. If the ball dies, he’s chopping. Reset and go again.
Max-velocity swings
Once he’s warm, these are the swings that actually move bat speed. You’re looking for intent — not a prettier swing. When the speed drops, the block is over.
In the yard. Same tee and net. Fully rest between rounds. You do not need a blast sensor tonight. You can hear when it gets loud.
Heavy bat
A college hitting coach walking through overload and underload. Steal the idea, not the equipment list. He cannot swing a heavy bat by leading with his hands. That’s the whole lesson.
In the yard. A 40–44 ounce bat if you have one, or two bats taped together. Tee, middle. Then put the game bat back in his hands. The barrel should feel light. No doughnut required.
Med-ball toss
Bat speed does not start in the hands. Watch the hips go first. Same idea as a swing, without a bat in the way. Just pure force into a wall or a net.
In the yard. A light medicine ball or a basketball against a garage, a fence, or a net. Hitting stride, throw it sideways. If you don’t have a med ball, skip it and hit.
His rounds
Let him choose. No lecture. The point of the last rounds is that he still wants to be out there. If you keep coaching, you stole that.
In the yard. Same net. His pick. You shag or you sit. Then you go inside.
