Brent Pourciau's Analysis

Road to 90

Personalized roadmap for Braxton Demopulos

📊 The Overview
Alright Braxton, here's your Road to 90. You're currently sitting at 91 mph — you've already reached 90! Time to set a new goal. Your overall profile is solid at the 61th percentile. There are clear opportunities to improve, and targeting the right ones will get you to 90.
🤖 What The AI Analysis Tells Me
Braxton, here's what jumps out at me — you're throwing 91 mph, but based on your physical profile, our AI model predicted you'd be around 83.5 mph. That's a +7.5 mph difference, which tells me your mechanics and motor patterns are already working in your favor. You're squeezing more velocity out of your body than most athletes with similar builds. That's a huge positive.
Your mechanics efficiency is in the 96th percentile — that's elite level. You're maximizing what your body gives you. At this point, adding velocity is about building a bigger physical engine because your delivery is already dialed in.
🎯 Your Biggest Opportunities
Based on the AI analysis, here are your biggest opportunities to add velocity:
Hip Rotation (Right) +0.7 mph
Current: 60.0° (23th %ile) Target: 70.0° (53th %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: 60.0° (27th %ile) Target: 70.0° (57th %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 Extension (Combined) +0.6 mph
Current: 25.0° (15th %ile) Target: 33.0° (45th %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 +7.2 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?
You've already hit 90 mph — congratulations! It's time to set a new target. Come back to the system and let's map out your path to the next milestone.
🚀 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. You're already in a good spot physically, so the 3X Program will help you refine and maximize what you've got. 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 Hip Abduction and Left Hip External Rotation.
Left Hip Abduction +0 mph
Current 40 °
Percentile 25th
Target 49 °
To Gain +9 °
Left Hip External Rotation +0 mph
Current 40 °
Percentile 50th
Target 44 °
To Gain +4 °
🔧 Supporting Work
After that, it's about the supporting package: Left Hip Flexion, left hip internal rotation (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 Maximum External Rotation and Dominate Arm External Rotation Speed 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 Maximum External Rotation
Current Percentile 60th
🎯 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
You've hit 90 — congratulations! Time to set a new target and run the analysis again. The system will identify the next set of variables to chase.
