Brent Pourciau's Analysis

Road to 90

Personalized roadmap for Chad McKenzie

📊 The Overview
Alright Chad, here's your Road to 90. You're currently sitting at 81 mph, which means you need about 9.0 mph to hit your target of 90. Your overall profile is solid at the 60th percentile. There are clear opportunities to improve, and targeting the right ones will get you to 90.
🤖 What The AI Analysis Tells Me
Chad, here's your reality check. You're at 81 mph, and the AI model predicted 83.4 mph based on your physical profile. You're pretty much right where you'd expect to be. This means you're efficiently converting your athleticism into velocity — no major mechanical leaks, but also room to grow both physically AND mechanically.
Your mechanics efficiency is at the 28th 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:
Hip Rotation (Right) +0.7 mph
Current: 67.0° (50th %ile) Target: 80.0° (80th %ile)
Why it matters: Hip mobility determines how much separation you can create between your hips and shoulders — that's where velocity comes from.
How we fix it: The 3X Program includes daily hip mobility protocols — 90/90 stretches, hip CARs, and dynamic mobility drills. The Stride Excelerator also helps groove proper hip mechanics.
Hip Rotation (Left) +0.7 mph
Current: 65.0° (40th %ile) Target: 75.0° (70th %ile)
Why it matters: Hip mobility determines how much separation you can create between your hips and shoulders — that's where velocity comes from.
How we fix it: The 3X Program includes daily hip mobility protocols — 90/90 stretches, hip CARs, and dynamic mobility drills. The Stride Excelerator also helps groove proper hip mechanics.
Hip Flexion (R) +0.6 mph
Current: 72.0° (25th %ile) Target: 80.0° (55th %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 = +2.0 mph potential
⚙️ The Mechanical Side
The AI also identified some mechanical variables from your motion capture data. There's about +7.8 mph worth of mechanical improvements available. These are things like trunk rotation speed, pelvis rotation, and arm timing — exactly what the 3X Pitching Velocity Program is designed to fix. The Trunk Excelerator specifically trains that rotational sequencing, and the Stride Excelerator grooves the lower half mechanics. This is where the real velocity unlocks.
🏆 Can You Hit Your Target?
Here's the best part — the math works. You need +9.0 mph to hit 90, and the improvements above give you +10.4 mph of potential. This is achievable. It's not going to happen overnight, but if you commit to the training and stay consistent, 90 mph is absolutely in reach.
🚀 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 left ankle dorsiflexion and Left Hip Abduction. Together, these account for about 0.5 mph of your velocity gap.
Left Ankle Dorsiflexion +0.2 mph
Current 5 °
Percentile 5th
Target 14 °
To Gain +9 °
Left Hip Abduction +0.3 mph
Current 20 °
Percentile 3th
Target 49 °
To Gain +29 °
🔧 Supporting Work
After that, it's about the supporting package: Left Hip External Rotation, Left Hip Flexion (mobility). These aren't the headline levers, but they raise the floor and make your mechanics easier to execute.
⚙️ Mechanical Focus
Mechanically, the key focus is Dominate Arm External Rotation Front Foot Strike and Dominate Arm External Rotation Maximum External Rotation. Most of the energy to the ball comes through the trunk, so trunk acceleration and sequencing are the big rocks to move.
Dominate Arm External Rotation Front Foot Strike +0.1 mph
Current Percentile 43th
🎯 Your Action Plan
Movement Cues:
"Shin down, leverage, drive — use the ground."
Training Priorities:
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.
