Dr. Brad Schoenfeld, PhD is one of the world’s leading researchers on muscle hypertrophy (muscle growth). He is a Professor of Exercise Science at Lehman College in New York, where he directs the Human Performance Laboratory. Over his career, he has published more than 300 peer-reviewed articles, book chapters, and textbooks on resistance training, body composition, and nutrition.

He is the author of Science and Development of Muscle Hypertrophy and The Max Muscle Plan, and has received prestigious honors such as the NSCA Young Investigator of the Year and the Dwight D. Eisenhower Fitness Award. Beyond academia, he has been a personal trainer and natural bodybuilding competitor, which allows him to uniquely bridge cutting-edge science with practical application.

Here's what he knows: the fitness industry has been selling you the wrong story. Not maliciously, but confidently. And most people are paying the price without even realizing it.

In this episode, Brad reveals why so many people are working harder than they need to while missing the basics that matter most. We discuss the beliefs keeping women from reaching their potential, the risks that sneak up when you avoid certain types of training, and what actually determines whether you stay strong and independent decades from now. He also tackles the myths around supplements, workout structure, and whether you're doing enough or too much.

If you're ready to stop spinning your wheels and start training smarter, this conversation will show you exactly where to begin.

Today I’m joined by Dr. Lara Briden, a naturopathic doctor, best-selling author, and internationally recognized expert in women’s hormones for a wide-ranging conversation on cycle health and why ovulation is a vital sign of wellbeing.

We talked about how monthly ovulation creates hormones that support bones, metabolism, and brain function, and what happens when that rhythm is disrupted by stress, restrictive eating, or birth control. Dr. Briden explains why natural estradiol and progesterone are so protective, how they differ from synthetic hormones, and what that means for both younger women and women approaching perimenopause.

She also shares her perspective on missing periods, hypothalamic amenorrhea, and the four functional types of PCOS, along with the growing role of insulin resistance in hormone imbalance. We talk about how to track ovulation, what lab markers to look for, and why restoring cycles is one of the most powerful steps for long-term health.

Brigid Titgemeier, a functional medicine dietitian and founder of Being Brigid Nutrition, has seen countless women walk into her clinic exhausted, bloated, and frustrated despite eating all the right foods.

What if aging wasn’t just something that happens to us, but something science could actually slow down? That’s the question at the heart of today’s conversation with Dr. Matt Kaeberlein, who’s a leading scientist and longevity researcher at the University of Washington.

Dr. Kaeberlein has spent decades decoding the biology of aging, from cellular mechanisms to practical strategies that could extend not just how long we live, but how well we live. In this episode, we talked about surprising connections between aging and brain health, and looked into the research around lithium and Alzheimer’s to see what the latest science is telling us about extending healthspan.

It is an informative discussion on whether aging itself can be slowed or reversed. If you’re curious about how close we really are to changing the rules of aging, this could be worth a watch.
