About Jonah Rosner

After 10+ years working with the most elite athletes in professional sports—including my time with the Houston Texans—I discovered something shocking: The \"common wisdom\" about marathon training is dead wrong. Now I help runners PR using the same sports science that keeps pros at the top of their game. No BS, just peer-reviewed performance. The result? 70% of our athletes hit personal records within 16 weeks. Here\'s how. THE PROBLEM I SOLVE: You\'re logging the miles. Following the plan. Yet you\'re still stuck at the same pace you ran 2 years ago. Meanwhile, your Instagram feed is full of: → Influencers pushing detox teas → Coaches recycling 1980s training methods → \"Experts\" who\'ve never read a single study You\'re drowning in contradictory advice, and it\'s costing you PRs. WHAT MAKES MARATHON SCIENCE DIFFERENT: 25+ PhDs on our advisory board (not influencers) Every recommendation backed by peer-reviewed research Pro sports methods adapted for everyday athletes Real data: 70% of clients PR (we track everything) I believe evidence beats hype. Always. HOW I HELP:**Weekly Newsletter subscribers):** Breaking down complex research into Tuesday morning game plans you can actually use.**SAC Training Community:** 16-week cohorts where we implement the science together. Small groups, big results.**Daily Science Drops:** Follow my posts for myth-busting that challenges everything you thought you knew about training. READY TO TRAIN SMARTER?

1. Founder & Head Sport Scientist

   Abis

   Jan 2023 — Present · New York, NY, US

   After spending over a decade as a sport scientist in the highest levels of professional sports, I founded Abis to solve a fundamental problem: the revolutionary training methods used by elite athletes were not accessible to the dedicated amateurs who needed them most.Today, Abis is a complete performance ecosystem dedicated to closing that gap. We arm runners and hybrid athletes with the scientific rigor and data-driven strategies once exclusively reserved for the pros, eliminating the \"junk miles\" and \"bro-science\" that lead to plateaus and injury.We achieve this through a multi-faceted performance ecosystem: AI-POWERED TRAINING TECHNOLOGY:We are at the forefront of personalized fitness, developing AI-driven training applications that provide dynamic, individualized adjustments to training, recovery, and nutrition based on an athlete\'s real-time data. THE SAC TRAINING COMMUNITY:Our premier 16-week coaching program where we guide small cohorts through implementing the core pillars of elite performance. This is a hands-on application of our science, leading to a 70% personal record (PR) rate for our members. THE MEDIA & NEWSLETTER HUB:With a readership of over athletes, our newsletter,\"Marathon Science\" serves as the engine of our community. We break down complex, peer-reviewed research into actionable weekly game plans, directly challenging the misinformation prevalent in the fitness industry.OUR FOUNDATION & AUTHORITY:Our methods are not theoretical. They were forged and validated in the most demanding environments, including:The NFL (Houston Texans)Nike NYC Performance LabConsulting for world-class professional athletes and organizations.Every protocol we release is vetted by our advisory board of 25+ PhDs and elite coaches, ensuring everything we do is effective, evidence-based, and built to deliver measurable results.
