Jackson Dennies

Alright Jackson, here's your Road to 90. You're currently sitting at 86 mph, which means you need about 4.0 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.

Jackson, here's what jumps out at me — you're throwing 86 mph, but based on your physical profile, our AI model predicted you'd be around 79.8 mph. That's a +6.2 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 91th 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.

Based on the AI analysis, here are your biggest opportunities to add velocity:

Here's the best part — the math works. You need +4.0 mph to hit 90, and the improvements above give you +5.9 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.

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.

The two biggest physical drivers for you right now are broad jump and Left Lateral Broad Jump. Together, these account for about 0.8 mph of your velocity gap.

After that, it's about the supporting package: Left Hip Abduction, Left Hip External Rotation (mobility), Left Rotational Power (power/stability). These aren't the headline levers, but they raise the floor and make your mechanics easier to execute.
