A new name, a wider lens, and a promise to cut through the noise — welcome to The Anthony Amen Show (formerly Health & Fitness Redefined), the official podcast supporting the mission behind Redefine Fitness, our high-end personal training studios in Stony Brook and Mount Sinai, NY. We open the new chapter by tackling one of the biggest problems in health: people chase the scale instead of the signals that actually change their bodies, their energy, and their long-term health.
Our guest, Jason, cofounder of Elite HRV and the camera-based body composition platform Spren, shows how better metrics and smarter tools turn effort into results you can finally understand. We trace his path from building analytics in the oil industry to democratizing HRV, and now to turning your phone into a near-DEXA body composition scanner. The goal? Clarity. Instead of obsessing over BMI or weight alone, we shift the focus to body fat percentage, lean mass, and fat distribution — because these are the markers that drive performance, aesthetics, metabolism, and longevity.
Jason breaks down visceral fat and the android:gynoid ratio as practical proxies for real health risk. We go deep on why lean mass is one of the leading indicators of aging well, metabolic resilience, and long-term independence. We also tackle modern dilemmas we see every day at Redefine Fitness: “skinny fat” bodies that look fine but hide internal risk, and GLP-1 users losing as much muscle as fat — and how resistance training and protein protect what truly matters.
Then we get tactical. Your Basal Metabolic Rate is a starting point, not destiny. NEAT, genetics, behavior, and identity shifts shape your real maintenance needs. Small wins compound. Resistance training pays interest daily by improving sleep, mood, movement, and the ability to do hard things without burnout. We look ahead to how AI will support future health coaching — letting software handle the spreadsheets while coaches and community bring empathy, context, accountability, and the human touch that actually drives change.
This episode is about simplicity, not surveillance. Track the few metrics that change outcomes. Let your data guide the next right step. And let strength carry the rest.
