The Speed Lab Podcast Eccentric Loading and Sprint Mechanics for Long Term Athlete Development: Colby Wartman, Origin Performance
Mar 13, 2026
Colby Wartman, owner of Origin Performance and Speed Lab director, blends eccentric loading and sprint mechanics into long-term athlete development. He discusses the TreadMetrics eccentric leg press, practical alternatives like depth jumps, and cues for improving ground attack. They also cover burnout risks in youth sports and how to shift programs to prioritize measurable speed.

Episode notes
Coach Saved Colby During Addiction Recovery
- Colby credits Coach Stanton with saving his life by treating him as a human during his opioid addiction recovery.
- That mentorship shaped Colby's coaching values and underpins why he emphasizes personal care in athlete development.
Eccentric Absorption Is A Prerequisite For Speed
- Eccentric strength to absorb high-speed forces is a prerequisite for sprint performance and injury resilience.
- Colby learned from Pete Leno that sprinting itself is the only true mimic of full-speed eccentric demands, so other tools are supplemental.
Measure Isometrics And Target Asymmetry
- Use isometrics and overloaded eccentrics to quantify and raise peak force and RFD when available.
- Colby uses a TreadMetrics eccentric leg press for double/single-leg ISOs and eccentric tests to track asymmetry and progression.
