Brent Pourciau's Analysis
Road to 90
Personalized roadmap for Ethan Stiles
The Overview
Alright Ethan, here's your Road to 90. You're currently sitting at 74 mph, which means you need about 16.0 mph to hit your target of 90. You're early in your development journey at the 31th percentile. At this stage, almost everything you work on will help — mobility, strength, power, and motor control all move the needle.
What The AI Analysis Tells Me
Ethan, let me break this down for you. You're sitting at 74 mph right now, and our AI model — which has analyzed over 800 elite athletes — predicted 73.5 mph based on your physical metrics. You're actually beating that prediction by 0.5 mph. That means your mechanics are doing their job. You're not leaving velocity on the table from inefficiency.
Your mechanics efficiency is at the 52th percentile — that's solid, right around average for our database. You're neither leaving a ton on the table nor maximizing everything. This is a good sign because it means improvements in BOTH your physical profile AND your mechanics will translate to velocity.
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.
Lateral Broad Jump
+2.0 mph
Current: 126.0" (3th %ile)
→
Target: 150.0" (33th %ile)
Why it matters: This measures your lateral power — critical because pitching involves a massive lateral push off the rubber before you rotate.
How we fix it: The Stride Excelerator trains this lateral drive pattern specifically. Combine it with lateral bounds and the TopVelocity Sled for lateral resisted work.
Vertical Jump
+1.8 mph
Current: 25.0" (40th %ile)
→
Target: 27.0" (70th %ile)
Why it matters: Vertical jump measures your explosive power — your ability to generate force quickly. This directly translates to how hard you can drive off the rubber.
How we fix it: The Impulse Ground Force Trainer develops your ability to create force into the ground explosively. Pair it with box jumps, depth jumps, and Olympic lift variations in the 3X Program.
These three priorities alone = +5.9 mph potential
The Mechanical Side
The AI also identified some mechanical variables from your motion capture data. There's about +4.8 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 +16.0 mph to hit 90, and the improvements above give you +19.0 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. You've got some physical development to do, and the 3X Program includes the strength and power protocols to build that foundation while you're learning elite mechanics. 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 broad jump and Body Height. Together, these account for about 0.5 mph of your velocity gap.

Supporting Work
After that, it's about the supporting package: Left Hip Abduction, Left Hip External Rotation (mobility), Left Lateral Broad Jump, Left Grip Strength (power/stability). 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 +0.1 mph
Current Percentile

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.
Explosive Power
Jump training (box jumps, bounds) + Olympic lift progressions (cleans, hang cleans). Train fast to be fast.
Mobility & Stability
Daily mobility work (hips, ankles, t-spine) + longer holds. Add single-leg stability for pelvic control.
