Prime Athletics was founded with one mission: to bring elite-level physical development to dedicated baseball and softball athletes. Our training programs are built on a deep foundation of strength and conditioning principles, functional mobility, sport-specific biomechanics, advanced arm care, and proven velocity development systems.
Whether you’re just starting your athletic journey or you’re a high-level performer chasing the next edge, we’re committed to helping you break through plateaus and exceed your goals.
Prime Athletics is proudly owned and operated by John Snelten, who completed his collegiate career at Valparaiso University in 2009. With over a decade of experience in private instruction, coaching, and performance training, John brings unmatched dedication and insight to every athlete’s development that has helped develop over 150+ successful 90 mph stories since Prime’s inception.

John Snelten is the founder and program coordinator of Prime Athletics, where he has dedicated his career to developing high-level arms through a culture rooted in trust, accountability, and long-term growth. A former collegiate athlete at Valparaiso University from 2005 to 2009, John transitioned from player to coach with a clear purpose: to build something lasting for the next generation of athletes.
Since opening Prime in 2016, John has focused on creating individualized programming that not only challenges athletes physically but supports them mentally and emotionally through every phase of their development. His approachable, yet demanding style fosters trust and connection, allowing him to build lasting relationships that extend far beyond the training floor.
Backed by his NASM-CPT and TPI certifications, John blends science, experience, and instinct into a development model that’s both intuitive and proven. His goal isn’t just to get athletes to throw harder — it’s to equip them with the tools, habits, and confidence to succeed at the next level and beyond.
