Maximize Your
Potential

Maggie didn’t pick up a javelin until college. She grew up as a multi-sport athlete, and it wasn’t until a coach at the University of Nebraska recognized her potential as a thrower that her javelin career began.

What followed wasn’t a straight line.

She went from throwing 54 meters to 62 meters in a single year. Then, after years competing internationally, she made another major breakthrough in 2021 — jumping from 62 meters to over 67 meters and becoming the American Record holder.

Today, Maggie is a three-time Olympian who has competed on the international stage for more than a decade. But those breakthroughs didn’t come from simply training harder.

They came from constantly asking better questions, surrounding ourselves with great coaches and athletes, experimenting with different approaches, learning from mistakes, and figuring out which changes actually created results.

Sam’s path taught us that lesson in a completely different way.

After playing baseball for 12 years, he was cut from his high school team and found the javelin shortly afterward. With very little established javelin training around him, he began building much of his own training and became the top high school javelin thrower in the country his senior year.

In college, he threw 73 meters as a sophomore and 74 meters as a senior — but despite training incredibly hard, the big breakthrough he was chasing never came.

Injuries eventually exposed something important: effort wasn’t the problem. Understanding was.

He had worked hard, but he hadn’t always been focusing on the things that mattered most.

That realization sent him down a different path — studying the event more deeply, talking with some of the best current and former javelin throwers and coaches in the world, and working to understand not just what great throwers do, but why it works.

That knowledge became even more powerful when our careers came together. Sam has coached Maggie through two Olympic Games and was part of the process behind her biggest career breakthrough in 2021. Together, we’ve spent years testing ideas in real training environments, competing at the highest level of the sport, learning from world-class coaches and athletes, and continuing to refine how we develop throwers.

And we’ve made plenty of mistakes along the way. That may be one of the most valuable things we can offer you.

We want to help athletes avoid spending years working incredibly hard on the wrong things. Because whether your next jump is from 30 meters to 40, 50 to 60, or 60 to 70, the challenge is often the same:

You have to identify what is actually holding you back — and then build the right training around it.

That’s what we want JVLN Performance to help you do.

We believe great javelin throwers are built as complete athletes. That means developing speed, power, strength, movement, coordination and technical skill together — not treating the throw as something that exists in isolation.

It also means recognizing that every athlete is different. We don’t believe there is one perfect technical model or one training program that works for everyone. We want to understand you — your strengths, your limitations, your training environment, your goals and the coaches already in your corner.

We love collaborating with personal coaches, strength coaches and support teams because our goal isn’t to replace what is already working. It’s to help connect the pieces.

We’re still curious. We’re still learning. We’re still evolving. But after decades spent throwing, coaching, competing, studying and making mistakes ourselves, we have a much clearer understanding of what helps athletes make the next jump.

And wherever that next jump is for you, we want to help you get there.

You’re not just getting a program. You’re getting two people in your corner who genuinely care about helping you become the athlete and thrower you’re capable of becoming.
