Listeners learn how the global race footprint and denser North American schedule change the cost–benefit math of frequent ra...

Why did Miles's stomach fall apart at mile fourteen of an eighteen-mile long run, despite doing everything right the night before with the classic pasta dinner? Amara breaks down why pre-race carb loading fails most recreational runners and what actually works with Berlin five and a half weeks out. Listeners learn the real gram-per-kilo carb targets for race week and why under-eating, not overeati...

What actually happens inside an Achilles tendon that hurts on the first steps of a run but eases once you're warmed up? Miles and Amara open up about their own flare-ups this week and use them to dig into the science of tendinopathy just as most fall marathoners hit peak mileage for Berlin, Chicago, and New York. Listeners will learn why tendon pain is a load-tolerance problem rather than inflamma...

What's actually happening in your body during taper week, and when should lifters-turned-runners stop strength training before race day? This Tuesday's episode breaks down peak week, taper, and supercompensation, then tests whether the taper research holds up once a botched long run enters the picture. Listeners will learn how detraining research explains a two-week strength window before real los...

What actually separates natural muscle building from enhancement, and does the math behind those viral "is he natty" videos hold up? Miles and Amara dig into the FFMI formula fueling the Jeff Nippard debate, tracing its 25 cutoff back to a 1995 study of 157 lifters. Listeners learn how that number was calculated, why body fat measurement error and DEXA scan margins can shift someone across the nat...

Marathon training season is here, and the question every lifter signing up for a fall race eventually asks is the same: how much squat strength will this cost me? Miles and Amara break down what really happens to strength during high-mileage endurance training, separating outdated interference-effect fears from what current research and their own training logs actually show. Listeners will learn w...

Can you get stronger and build endurance at the same time, or does one always undercut the other? Miles and Amara dig into the interference effect, the molecular tug-of-war between mTOR and AMPK that explains why heavy lifting and long cardio sessions sometimes work against each other. Listeners will learn where the original 1980 research on this tradeoff came from, why doing strength work before...

Does Ozempic actually eat your muscle, or is that gym-floor warning oversimplified? Miles and Amara dig into a University of Utah mouse study showing most GLP-1-related lean mass loss comes from organ shrinkage, not skeletal muscle, then unpack apitegromab, a myostatin-blocking drug tested with tirzepatide that showed real lean mass retention in early trials. Listeners will learn why strength can...

How much strength training do you actually need to lower your risk of dying from heart disease, Alzheimer's, or any cause? A 30-year Harvard study tracking nearly 150,000 adults puts a number on it — and the answer is more achievable than most people assume. Miles and Amara break down exactly where the longevity benefit peaks and why adding more volume past that point returns nothing extra. You wi...

Does drinking more water actually solve your hydration problem — or is volume the wrong variable entirely? Miles and Amara dig into why two liters of plain water left Miles salt-crusted and foggy after a heat training session, and what the research says about why generic hydration advice fails a significant portion of athletes.
