"Your system turned a very-bottom-of-the-order 12U player into a #3-in-the-order-all-season confident 13U hitter."
Bruce Bergen โ Youth baseball coach
Coaches are teaching the bent lead arm โ and the data says it's costing hitters on the pitches that matter most.
Here's the thing about up-and-in fastballs: they're the most dangerous pitches to miss on. A pop-up on an up-and-in fastball is an easy out. A line drive on the same pitch is a game-changer. The difference, according to Perry Husband's 5,000-swing experiment, comes down to one thing โ lead arm position.
Mike Trout's exit velocity gap: 80.8 mph avg (bent arm, up/in) vs. 101.8 mph avg (locked arm, down/away) โ same hitter, same year, 2018 Statcast data.
โ Perry Husband, EffectiveVelocity.comThe bent lead arm creates an elbow bend that absorbs elastic energy before it can transfer to the barrel. Think of it like a bungee cord with slack โ it can't snap back with full force. The locked out lead arm removes that slack, making the rotational chain one continuous lever from the hips to the barrel tip.
And here's the common coaching mistake: many coaches tell hitters the locked arm causes casting. It doesn't. Casting is caused by when the barrel releases from the rear shoulder โ not by the lead arm position. A hitter can have a perfectly short swing with a locked lead arm when they hold the bat angle against the following shoulder through the start of rotation.

The 21 mph Statcast Split โ Visualized
Locked arm vs. bent arm exit velocity comparison from Mike Trout's 2018 Statcast data, with the pitch location breakdown that makes it clear.
Locked vs. Bent โ Side-by-Side Comparison
Six checkpoints for each approach: lever length, energy transfer, pitch coverage, pro examples (Jay Bell, Stanton, Donaldson), and what goes wrong when the arm bends at contact.

The bungee principle, the deep barrel dump problem, the casting myth debunked, the golf parallel โ condensed to bullet points you can reference in 30 seconds.
The A/B Test Protocol โ Prove It in One Session
A 3-step tee drill: 20 swings bent, 20 swings locked, compare avg exit speed. The protocol works with any exit speed sensor โ Rapsodo, Blast, or similar.
What Coaches Are Saying
Trusted by coaches and players at every level
"Myers is way out front. I've studied hitting and coached at DI and 3 levels and this approach blew me away with what I wasn't seeing even though it was right in front of my face. It's like going from earth is flat to earth is round."
Dr. Tom Hanson โ DI Hitting Coach, author of Heads-Up Baseball (Kindle, Verified Purchase)
"I changed my 10yr old to this style midway through the season. He was batting .320 with no HRs. Last 30 games he batted .560 as a righty and .584 as a lefty with 5 HRs!"
Jack A. Martin โ Youth baseball coach & parent (via Facebook)
"I am a Physical Therapist โ your stuff in body movements is awesome. I went to some FMS courses and Gray Cook spoke highly of you. Your approach is truly the best because of your use of anatomy and kinesiology."
Jay Finton โ Physical Therapist (via email)
"Your system turned an unsure, very-bottom-of-the-order 12U baseball player into a #3-in-the-order-all-season confident 13U hitter."

Quick Questions
Is the locked out lead arm right for youth hitters?
Yes โ the principle relies on lever length and elastic energy transfer, not strength. Youth hitters with less rotational power often see the biggest gains from removing the energy leak at the elbow. The A/B test protocol in the blueprint works at any age with any exit speed sensor.
My coach says the locked arm causes casting. Is that true?
No โ and this is the most common misconception. Casting is caused by when the barrel releases from the rear shoulder, not by lead arm position. Perry Husband's 5,000-swing research addressed this directly. The blueprint explains the distinction and includes the specific cue that prevents casting while keeping the arm locked.
What equipment do I need to run the A/B test?
Just a batting tee and any exit speed sensor โ Rapsodo, Blast, or similar. The test takes about 10 minutes of batting practice time. No sensor? The contact quality difference is usually audible โ and your hitter will feel it immediately on the bent-arm vs. locked-arm reps.
