Brent Pourciau's Analysis
Road to 90
Personalized roadmap for Brandon Rollinson
The Overview
Alright Brandon, here's your Road to 90. You're currently sitting at 79.8 mph, which means you need about 10.2 mph to hit your target of 90. Your profile is in the 40th 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
Brandon, here's what jumps out at me — you're throwing 79.8 mph, but based on your physical profile, our AI model predicted you'd be around 74.7 mph. That's a +5.1 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 at the 85th percentile — that's excellent. You're converting your athleticism into velocity very well. There may be small refinements we can make, but the big wins will come from improving your physical profile.
Your Biggest Opportunities
Based on the AI analysis, here are your biggest opportunities to add velocity:
Broad Jump
+2.1 mph
Current: 92.0" (32th %ile)
→
Target: 100.0" (62th %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: 154.0" (42th %ile)
→
Target: 164.0" (72th %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.
Right Grip Strength
+1.8 mph
Current: 100.0 lbs (32th %ile)
→
Target: 110.0 lbs (62th %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.
These three priorities alone = +5.9 mph potential
Can You Hit Your Target?
Here's the best part — the math works. You need +10.2 mph to hit 90, and the improvements above give you +12.5 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 Total Body Strength. Together, these account for about 2.4 mph of your velocity gap.

Supporting Work
After that, it's about the supporting package: vertical jump, Left Lateral Broad Jump (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.
Explosive Power
Jump training (box jumps, bounds) + Olympic lift progressions (cleans, hang cleans). Train fast to be fast.
