Every hitter wants more bat speed, and most go about it exactly backwards — they try to swing harder, grab a lighter bat, or hunt for a magic wrist move. Here's the thing that changes everything: slow hands almost never mean weak hands. They mean a long, disconnected swing. Fix the swing and the speed shows up, because it was there the whole time.
Speed is a chain, not a muscle
Bat speed isn't manufactured in your forearms. It's manufactured in a sequence: weight gathers into the back hip, the hips fire toward the pitcher, the shoulders follow a beat later, and all of that whips the barrel through at the end. When the chain fires in order, the barrel arrives fast with almost no arm effort. When a link is out of order — you spin as one block, or you cast the hands out early — the chain leaks, and the hands look slow no matter how hard you try.
That's why "swing harder" fails. Harder usually means firing everything at once, which breaks the chain. Real quickness comes from a shorter, more connected swing and a better-sequenced turn.
What the camera can — and can't — read
Film open side and CoachVision measures your hand speed through the zone, in torso-lengths per second, so body size doesn't skew it. But read this one carefully, because honesty matters most here:
It's a hand read and a quickness proxy — not bat speed, and definitely not mph. The camera can't see your bat, and the barrel moves far faster and farther than your hands. There's no radar gun involved. Absolute hand speed also depends on your body and your camera, so it's the lowest-weight read in its group and it's most useful compared against your own past swings, not anyone else's number.
The far more useful reads for a "slow bat" are swing length (a long swing is a slow-arriving one) and hip-shoulder separation (a swing that fires in order is a fast one). Slow hands are almost always a symptom — chase the cause.
The fix — build the engine, then let speed follow
Med-Ball Rotational Throws train the chain under a little resistance: from your batting stance, load the back hip, fire the hips first, and let the arms come along late to throw the ball into a wall. The throw is impossible without a full, sequenced turn — so it grooves the exact order that makes hands fast. Three sets of six each side, with a ball you can throw with intent, not strain.
A safety word, because bat speed is where hitters get hurt chasing it: never chase speed with effort, especially younger hitters. Chase it with the chain. Order and rhythm add speed and protect your back and obliques; "swing as hard as you can" does neither.
Film one open-side swing, look at your swing length and separation before your hand speed, then build the turn with med-ball throws — and let the quickness show up as the byproduct it's meant to be.
