Vertical Force Production Protocol

If you're an athlete who's tired of feeling slow off the ground, watching your vertical stall out, or dealing with knee pain every time you push hard in training, this plan is for you. Most athletes chase height without understanding the foundation: your body has to absorb force before it can produce it. You need stability before explosiveness. You need balance before max effort. That's where most programs fail—they skip the fundamentals and leave you injured or stuck at the same numbers month after month. This six-week protocol walks you through the exact progression I use with athletes who want to move like professionals. You'll develop concentric strength through seated and weighted box jumps, train your body to produce vertical force as fast as possible, eliminate the muscle imbalances that kill your performance, and build bulletproof joint stability so your knees and ankles can handle the load. Every week builds on the last. Every session has a clear focus. You're not just jumping—you're teaching your nervous system to fire faster, training your tendons to store and release energy efficiently, and giving your body the tools to change direction without breaking down. I'm Adonis Harrison Jr., a functional training coach and Air Force veteran who's spent years working with athletes on explosive power development. I've hit 60-inch box jumps and built programs that keep athletes healthy through entire seasons. This isn't theory. It's the same system I use in my own training and with every athlete who walks through my door. If you're ready to move better, jump higher, and stay healthy while you do it, let's get to work.
