Most training is guesswork.
High school athletes train hard. They go to camps. They lift. They run. But without objective movement data — and an expert to interpret it and guide development over time — they’re building on guesswork.
College sport demands precision: the data, and the ongoing guidance to act on it.
Trainers and strength coaches may come and go. P3 is designed to deliver persistent intelligence.
Not a camp. Not a combine. A development system.
Your P3 Athletic Profile
Built by P3’s biomechanical engineers.
Backed by 20 years of research and the deepest athlete movement database in the world. Every metric is reported as a percentile against that database.
20 years. 5,000+ athletes. The standard in human movement.
P3 was founded by Dr. Marcus Elliott, a Harvard-trained physician who pioneered 3D motion capture and force plate assessment in professional sport. Dr. Elliott is the 12th Augustus Thorndike Lecturer at Massachusetts General Hospital — the most prestigious lectureship in American sports medicine.
P3’s research has been published in peer-reviewed journals. The 2025 book Ballistic tells the full story — named a Next Big Idea Club selection and reviewed in the Wall Street Journal.
Over two thousand P3 high school athletes have earned college scholarships.
They came to P3 for exactly this.
Assessment, training, and training advice — the same three things a College Prep athlete gets. Several of them first came as high schoolers, before we had a name for the program. Luka was sixteen.
Trusted at every level.
As seen in the Wall Street Journal, ESPN The Magazine, Sports Illustrated, NBA.com, Fast Company and The New Yorker.
"My body feels better now than it did at 23 — and that doesn’t happen in pro sports."
Kyle Korver, NBA All-Star, 18-year career
"They focus on trying to balance out your body. I learned more about the body."
Kawhi Leonard, ESPN The Magazine
"When you have a prospect that young, the earlier you can expose him to P3 the better."
Bill Duffy, NBA agent, on Luka Dončić, Wall Street Journal
Don’t wait for injury.
P3’s proprietary models identify mechanical risk factors before they become problems. Trained on 20 years of outcome-linked data from over a thousand professional athletes, they don’t exist anywhere else.
The same mechanics behind those NBA knee injuries show up in high school athletes, usually years before anything hurts, and while there is still time to change them.
The people behind your program.
P3 College Prep athletes are guided by Lead Performance Coaches who work across every level of competition — from youth development through the professional and Olympic ranks.
Nick Potthoff — Lead Performance Coach, Santa Barbara. Nick joined P3 in 2023 and oversees athlete development for youth, collegiate and professional athletes. He holds a master’s in Applied Sports and Exercise Science from the University of Derby, and competed professionally overseas.
Tom FitzSimons — Lead Performance Coach, Atlanta. Tom joined P3 in 2022, having coached at the Olympic, collegiate and youth level, including combined-events athletes at the 2016 and 2020 Olympic Games. He competed professionally as a decathlete and won bronze at the 2014 USA Track & Field Championships.
What the program includes
- A full biomechanical assessment at P3 in Santa Barbara or Atlanta - 3D motion capture and force plates.
- Findings reviewed with you in person the same day, before you leave.
- Two individualized training sessions, teaching the specific work the assessment identified.
- A report on findings.
- A dedicated P3 advisor for the program year.
- An advisory call every two months — six across the year — with guidance updated after each one.
- A reassessment at about twelve months, in a window that fits your sport calendar, at a returning-athlete rate.
Working with your coach. If your athlete trains with someone — a school strength coach, a club program, a private trainer — we are glad to work with them directly, with your athlete on the call, so everyone is building from the same picture. If your athlete does not have a coach, the program is built to be run on their own, and the two training sessions exist to teach it properly.
What we don’t do. If your athlete is working through an injury, we can make suggestions — but rehabilitation depends on consistent in-person oversight from a professional, which we can’t provide remotely. We’ll always tell you what we can and can’t help with.
Availability. The program is offered on a limited basis, so every athlete gets the time they need from the person responsible for them.
Tell us about your athlete and what they are working toward. We review every application and will come back to you either way.
