About JVLN

Built From
The Field Up

We’re Maggie & Sam — and between us, we’ve lived this sport at its highest levels, but we both started from humble beginnings.

Maggie grew up playing a variety of sports in high school and didn’t pick up the javelin until college, when her coach at the University of Nebraska saw her potential as a thrower. Sam spent 12 years as a baseball player before converting to the javelin his junior year of high school — after being cut from the baseball team.

Together, we’ve traveled the world as athletes and coaches, training alongside and learning from some of the best minds in our sport. That knowledge is the foundation of everything we build at JVLN Performance.

Our programs reflect everything we’ve learned, and we believe the key is developing throwers as complete athletes. We train our athletes to be high-capability sprinters, jumpers, and movers, because we know that overall athleticism is what allows technique to truly come alive.

In high school, I played softball and volleyball and competed in multiple events in track.

I finished my collegiate career at Texas A&M as an NCAA Champion and the women’s collegiate javelin record holder at the time. After college, I competed in my first Olympic Games in 2016 in Rio de Janeiro, Brazil. Since then, I’ve represented Team U.S.A. at home and abroad across two World Championships and three Olympic Games.

Athlete Testimonials

Coach Marcus broke down my release angle in the first session. The programming is dialed. I’ve never felt more prepared going into conference.
Sam Okafor
Collegiate Thrower · PR 61.2m
As a masters athlete I was worried about injury risk. The JVLN team built a program around my recovery needs without sacrificing intensity. I threw a PR at 48.
