Brent Pourciau's Analysis

Road to 90

Personalized roadmap for Lajamiean Johnson

📊 The Overview
Alright Lajamiean, here's your Road to 90. You're currently sitting at 68 mph, which means you need about 22.0 mph to hit your target of 90. Your profile is in the 47th percentile overall, which means there's significant room to grow. The good news? Every improvement you make will translate to velocity.
🤖 What The AI Analysis Tells Me
Lajamiean, let me be real with you — this is actually exciting news. You're throwing 68 mph, but based on your physical metrics, the AI model says you should be around 74.7 mph. That 6.7 mph gap? That's not a problem — that's POTENTIAL. It means once we clean up your mechanics and movement patterns, you've got velocity sitting there waiting to be unlocked.
Your mechanics efficiency is at the 8th percentile — and honestly, this is where the opportunity is. Your physical tools are there, but your delivery isn't converting them efficiently. The good news? Mechanical improvements often come faster than physical gains. Once we optimize your sequencing and timing, you'll see immediate velocity jumps.
🎯 Your Biggest Opportunities
Based on the AI analysis, here are your biggest opportunities to add velocity:
Broad Jump +2.1 mph
Current: 98.0" (54th %ile) Target: 106.0" (84th %ile)
Why it matters: Your broad jump is one of the best predictors of pitching velocity because it measures your ability to produce horizontal force — exactly what you need off the mound.
How we fix it: The Stride Excelerator is perfect for this — it trains the exact horizontal force production pattern you use in your delivery. Combine that with plyometrics, bounds, and the TopVelocity Sled for resisted stride work.
Left Grip Strength +1.8 mph
Current: 75.0 lbs (7th %ile) Target: 100.0 lbs (37th %ile)
Why it matters: Grip strength is the end of the kinetic chain. All that force you generate has to transfer through your hand to the ball.
How we fix it: Farmer carries, dead hangs, wrist work, and specific grip training in the 3X Program. This also helps with spin rate and command.
Vertical Jump 225 +1.8 mph
Current: 15.0" (12th %ile) Target: 19.0" (42th %ile)
Why it matters: This metric has a direct correlation to pitching velocity based on our data from over 800 athletes.
How we fix it: The 3X Pitching Velocity Program includes specific protocols to target this. Combined with the TopVelocity training devices, you'll see improvement quickly.
These three priorities alone = +5.7 mph potential
🏆 Can You Hit Your Target?
Let me be honest with you — getting to 90 mph is a big goal. The improvements I've outlined give you about +12.6 mph, which would put you around 80 mph. That's a great interim target. The remaining 9.4 mph will require elite-level development — we're talking about pushing past 90th percentile on multiple metrics. Set 80 mph as your first milestone, crush that, then we'll re-evaluate and map out the next phase.
🚀 My Recommendation
Based on everything I'm seeing here, here's what I recommend: The 3X Pitching Velocity Program is exactly what you need. This isn't just a throwing program — it's a complete system that addresses mechanics, strength, power, and motor learning all in one. Your mechanics efficiency score tells me there's velocity sitting on the table right now. The 3X Program will teach you how to sequence your body properly and transfer all that force into the ball. To accelerate your results, I highly recommend using the TopVelocity training devices that are built into the program: The Trunk Excelerator teaches you to generate and transfer rotational power through your core — this is where velocity lives. The Stride Excelerator builds explosive leg drive and proper stride mechanics, which is the foundation of the 3X approach. The Impulse Ground Force Trainer develops your ability to create force into the ground, and the TopVelocity Sled builds the specific strength patterns you need for a powerful delivery. These aren't gimmicks — they're tools designed to train the exact movement patterns that separate high-velocity pitchers from everyone else. Combine them with the 3X Program and you'll see results faster than training alone.
💪 Your Top Physical Priorities
The two biggest physical drivers for you right now are Total Body Strength and broad jump. Together, these account for about 3.1 mph of your velocity gap.
Total Body Strength +2.4 mph
Current 290 lbs
Percentile 12th
Target 533.3 lbs
To Gain +243.3 lbs
Broad Jump +0.7 mph
Current 98 in
Percentile 58th
Target 102 in
To Gain +4 in
🔧 Supporting Work
After that, it's about the supporting package: right shoulder external rotation, left ankle dorsiflexion (mobility), Left Grip Strength (power/stability), Body Height. These aren't the headline levers, but they raise the floor and make your mechanics easier to execute.
🎯 Your Action Plan
Movement Cues:
"Shin down, leverage, drive — use the ground."
Training Priorities:
Build Mass
Calorie surplus + structured strength phases. Mass equals gas — you need more raw material.
Mobility & Stability
Daily mobility work (hips, ankles, t-spine) + longer holds. Add single-leg stability for pelvic control.
🚀 What's Next
Hit these targets, re-test, and the system will update the next set of variables to chase. This is iterative — each evaluation narrows the focus as your profile improves. Plan to re-evaluate in 8-12 weeks.
