Dr. Rhonda Patrick is a leading researcher in nutrition, aging, and metabolic health. She’s known for translating complex science into practical tools for longevity and performance. Now, after a year of doing CrossFit, she has new insights to share. In this episode, Rhonda joins Denise to break down the cellular mechanisms behind high-intensity exercise, why lactate is more than a waste product, and how CrossFit helps train your brain, not just your body.

They cover topics like VO2 max, mitochondrial repair, post-meal inflammation, aging muscles, and the science behind “exercise snacks.” Rhonda also shares her personal transformation from intimidated beginner to committed athlete and why she believes CrossFit may be one of the most powerful tools for lifelong health.

Topics Included

Why Rhonda started CrossFit — and how her perspective shifted after a year of training

What lactate actually is and why it’s a powerful signal for brain and muscle health

How high-intensity exercise triggers mitochondrial repair and neurogenesis

Dr. Stacy Sims is an exercise physiologist, nutrition scientist, TEDx speaker, and the bestselling author behind the viral phrase “Women are not small men.” In this episode, she joins Denise Thomas to unpack what we really need to know about women’s physiology — and how most training and nutrition advice completely ignores it.

They get into the menstrual cycle, perimenopause, postmenopause, and how to train through it all. Stacy explains why women lose power during certain phases, how training affects the brain, and what female athletes should do differently when it comes to strength, conditioning, recovery, and stress. They also break down cold plunges, sauna use, and why CrossFit coaches and gym owners have an opportunity to lead the way in changing the narrative.

Topics Included

Biological differences in training, recovery, and metabolism

Power, hormone shifts, and the menstrual cycle

When and how to modify workouts

Why fasting and cold plunges don’t affect men and women the same way

How to feel and perform your best during perimenopause and postmenopause

Raising the next generation of girls to understand their physiology for performance

Dr. Kelly Starrett joins the CrossFit Podcast to look back on the early days of CrossFit and ahead to what the next 20 years can become. From finding CrossFit through a grainy GIF in the early 2000s to opening one of the first affiliates in the world, Starrett reflects on the ideas that shaped the methodology and the lessons learned through decades of coaching athletes, Olympians, and everyday people.

This conversation explores durability over time, why pain is not a failure but a request for change, and how movement quality, range of motion, and basic strength set the foundation for performance at every age.

Starrett and host Jocelyn Rylee dig into the future of CrossFit, from longevity and conditioning to the irreplaceable value of affiliates as places built around coaching and community. This episode is an honest look at what CrossFit has always been about and what it can become if we apply what we have learned.

Topics Covered

The early days of CrossFit and the original affiliate culture

Mobility, durability, and reframing pain in training

Why youth athletes need movement literacy before specialization

Training for sport versus training only for fitness

The future of CrossFit and longevity-focused strength and conditioning

Community Highlight

Kristin Savage grew up around autoimmune disease. By age 5, she was dealing with joint inflammation, and years later, she was formally diagnosed with lupus.

She found CrossFit in 2012 and later trained and coached at CrossFit Gambit, where she was mentored by Kelly Jackson. Kristin earned her Level 1 and Level 2 Trainer credentials and now has aspirations to pursue her Level 4.

After a severe flare-up forced her to reassess how she trained, Kristin shifted her focus to nutrition, recovery, and scaled training — learning to work in rhythm with her body instead of against it. Within a year, she qualified for Desert City.

Today, Kristin coaches CrossFit in Las Vegas and spends much of her energy helping others navigate training and chronic illness — sharing what she’s learned through experience.
