Brent Pourciau's Analysis
Road to 90
Personalized roadmap for Jason Zhang
The Overview
Alright Jason, here's your Road to 90. You're currently sitting at 79 mph, which means you need about 11.0 mph to hit your target of 90. Your profile is in the 45th 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
Jason, let me break this down for you. You're sitting at 79 mph right now, and our AI model — which has analyzed over 800 elite athletes — predicted 78.2 mph based on your physical metrics. You're actually beating that prediction by 0.8 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 55th 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:
Left Grip Strength
+1.8 mph
Current: 100.0 lbs (36th %ile)
→
Target: 110.0 lbs (66th %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.
Right Grip Strength
+1.8 mph
Current: 110.0 lbs (53th %ile)
→
Target: 125.0 lbs (83th %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.
10-Yard Sprint
+1.5 mph
Current: 1.7s (38th %ile)
→
Target: 1.6s (68th %ile)
Why it matters: Your 10-yard sprint measures acceleration — first-step explosiveness. Pitching is all about that initial burst of power, not sustained speed.
How we fix it: The TopVelocity Sled is built for this — resisted sprints that develop first-step explosiveness. The 3X Program includes specific sprint protocols to improve your acceleration.
These three priorities alone = +5.1 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 +9.9 mph, which would put you around 88 mph. That's a great interim target. The remaining 1.1 mph gap can be closed through consistent training, mechanical refinement, and maturation. It's going to take time and work, but it's doable.
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 Total Body Strength and Body Height. Together, these account for about 1.6 mph of your velocity gap.

Supporting Work
After that, it's about the supporting package: Left Hip Abduction, Left Hip External Rotation (mobility), Left Grip Strength (power/stability). 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.
