Without Sam and Maggie, I honestly don’t think I would have gotten the opportunity to throw in college or at all.
KalliFormer Norris High School athlete · Now throwing at Iowa State -
They gave me a different perspective on throwing the javelin and were able to teach it in a way that really clicked with me.
EmryCollegiate javelin athlete -
I love how Maggie and Sam tailor workouts just for me and don’t provide a generalized workout. … I’ve also improved so much technically working with them, and my PR has improved by 5 meters.
FaithCollegiate javelin athlete · Milligan University -
They both want the best for you. They bounce ideas back and forth the entire time to try to fit your needs and find exactly what you need in your form.
LakinCollegiate javelin athlete · University of Nebraska at Kearney -
They’re great people. They want to see you succeed. They’re going to make sure you get the proper training.
NikoCollegiate javelin athlete · Emporia State University -
I couldn’t get past 43m but knew I had a bigger distance in me. I reached out to JVLN Performance and within 6 weeks I jumped to 48m. They provided a programme, weekly calls and technical changes.
KayJavelin athlete · Mom of two returning after a decade away -
Through their coaching, I have learned that throwing far does not simply mean throwing harder. It is about hitting the right positions at the right time and efficiently transferring power into the javelin.
MatthewCollegiate javelin thrower · Concordia -
They don’t just tell an athlete what needs to change; they take the time to explain why and help them understand how to make those adjustments successfully.
HadynHigh school javelin thrower · 2026 Kansas state champion -
As a heptathlete, balancing all the events can be tough, but Maggie and Sam provided the exact technical guidance I needed for the javelin. They break down the throw in a way that really clicks, tailoring workouts specifically to me.

Why JVLN
We know what it takes to make the next jump.
Maggie went from 177 feet to 203 feet in one year, and later reached a then-American record of 221 feet (67.40 m). Sam’s path took him from being cut from baseball to throwing javelin in college and coaching Maggie through two Olympic Games.
Those journeys taught us how much the right understanding can change your training. We bring those lessons into every coaching conversation: explaining what we see, listening to what you feel, and helping you choose what to work on next.
Bring us the goal you care about.
