Lifting Weights Builds Flexibility Better Than Stretching (New Research) | Ep 459
14/04/2026 | 26 mins.
Do you need yoga, stretching, or "mobility work" to stay flexible. Does lifting weights make you "stiff" or does it improve flexibility? We examine 3 recent studies that compared resistance training to stretching for flexibility, and their findings challenge everything most people assume about lifting weights and mobility. Philip covers the "lifting makes you stiff" myth and a training approach that builds flexibility and strength at the same time. If you're over 40 and worried about losing range of motion, this one's for you. Stay for the bonus 60-second squat test at the end. Upgrade your sleep to match your training with Cozy Earth.

5 Ways Intermittent Fasting Backfires for Women Over 40 | Ep 458
09/04/2026 | 35 mins.
Intermittent fasting is still the most popular nutrition advice on the internet. Skip breakfast, shrink your eating window, lose weight. But if you're over 40, this may not give you the results you want. It could even backfire. Learn about the 5 specific ways intermittent fasting can backfire when your goal is losing fat and building muscle after 40. Philip examines a 2025 meta-analyses comparing IF to standard dieting, the challenge of getting enough protein in a compressed eating window, recent findings on cortisol and hormonal effects that especially affect women in perimenopause, and a surprising 2025 review that challenges one of fasting's biggest marketing claims (hint: it's about inflammation). Plus, learn a structured meal timing alternative and 3 diagnostic questions to test whether your current eating window is causing issues for you.

The Mad Scientist's Guide to Strength Training After 40 (Chris Duffin) | Ep 456
02/04/2026 | 50 mins.
Why does lifting start hurting once you hit 40? Is it really age, or is your body compensating for weak links you cannot see?
Chris Duffin joins me to unpack the biomechanics behind strength training longevity, muscle building, and injury prevention. Chris is a world record strength athlete who has squatted and deadlifted over 1,000 pounds while applying engineering principles to human movement. We talk about why many lifters trying to build muscle and lose fat end up breaking down, especially with strength training over 40. Chris explains how breathing mechanics, foot stability, and movement quality determine whether your body adapts or gets injured. You’ll learn why poor mechanics “detune” your nervous system, how foot strength influences power and metabolism, and why proper bracing unlocks safer muscle building and hypertrophy. If you care about body recomp, lifting weights long term, and evidence-based training that supports longevity, this conversation is packed with insights.

About Wits & Weights | Evidence-Based Fitness & Nutrition for Lifters Over 40
Wits & Weights is a strength and nutrition podcast where in every episode I put a popular piece of fitness advice under the microscope, find the hidden reason it doesn't work, and give you the deceptively simple fix that does.For skeptics of the fitness industry who are tired of following the rules and still not seeing results. If you've been lifting weights, tracking macros, and doing "all the right things" but your body composition hasn't changed, you're probably overcomplicating it. This is the fitness podcast that shows you how to build muscle, lose fat, and achieve a real body recomp by focusing only on what the evidence actually supports.Evidence-based fat loss coach Philip Pape brings an engineer's approach to strength training, nutrition, and metabolism. Instead of another generic program or meal plan, you get specific, science-based strategies for optimizing body composition, whether you're focused on building muscle, losing fat, or both. The focus is on strength training over 40, hormone health, perimenopause and menopause, and longevity.You've seen the conflicting advice. One expert says cut carbs, the next says eat more. One says train six days a week, another says three is plenty. Building the body you want doesn't have to be this confusing or time-consuming. By using your wits (systems + identity-based behavior change) and lifting weights, you can build muscle definition, improve your physique, and maintain your results for life without rebound weight gain.You'll learn smart, efficient strategies for movement, metabolism, muscle, and mindset, such as:- Why fat loss matters more than weight loss for both your health and your physique- Why all the macros, including protein, fats, and yes even carbs, are critical to body composition- How just 3 hours a week of proper hypertrophy training can deliver better results than most people get in twice that time- Why building muscle is the single most powerful thing you can do for metabolic health, longevity, and aging well- Why perimenopause and menopause don't have to derail your progress when your training and nutrition are dialed in- How shifting the way you think about fitness can unlock more physical (and personal) growth than any program aloneIf you're ready to learn what actually works with evidence-based training and nutrition, hit "follow" and let's engineer your best physique ever!Popular Guests Include: Mike Matthews (author of Bigger Leaner Stronger), Greg Nuckols (Stronger by Science), Alan Aragon (nutrition researcher), Eric Helms (3D Muscle Journey), Dr. Spencer Nadolsky (Docs Who Lift), Bill Campbell (exercise science researcher), Jordan Feigenbaum (Barbell Medicine), Holly Baxter (evidence-based physique coach), Laurin Conlin (physique coach), Lauren Colenso-Semple (nutrition researcher), Karen Martel (hormone optimization expert), Steph Gaudreau (women's strength and nutrition), Bryan Boorstein (hypertrophy coach)Popular Topics Include: hormone health, metabolism optimization, hypertrophy training, longevity and healthy aging, nutrition tracking, best protein powder selection, strength training over 40, women's fitness, perimenopause, menopause, muscle building, body recomp, macros and nutrition tracking
