Jim Keen is back—and he’s tackling a misconception that’s been baked into isokinetic training since the beginning: that you have to go as hard as possible, every rep, every session, to get results. The key paradigm shift: strength training uses a tool to deliver stimulus to your muscles, while weightlifting uses your muscles to move a tool. When the goal becomes making a number go up on screen, form breaks down—and that’s where problems start.

The side effects people associate with GLPs are overwhelmingly tied to dosing too aggressively. Semaglutide (GLP only) is what she calls “inelegant and clunky.” Tirzepatide (GLP + GIP) is more complete, better tolerated, and effective at lower doses. Retatrutide (GLP + GIP + glucagon) is coming later this year for patients who are metabolically inflexible and resistant to tirzepatide.

Kimberly explains what endometriosis actually is—adhesions forming in the peritoneal cavity that attach to bowel, bladder, ovaries, and uterus. They’re invisible on imaging. The only way to see them is surgery. And the key question driving this episode: is endometriosis gynecological or metabolic? Resources: Quality-of-life survey

After 3 million views and thousands of comments, Kyle and Kimberly go deeper on PCOS—what causes it, why it’s been misunderstood, and why GLP deficiency may be the missing piece.

What is VO2 max, and why should you care about it? The short answer: yes. VO2 max measures the maximum amount of oxygen your blood can carry and deliver to your body under stress. A study of roughly 120,000 people found that moving from the bottom half of VO2 max rankings to the top half lowered the risk of all-cause mortality over the next ten years by 70%. And the best way to maximize your VO2 max? Developing and retaining muscle mass.

This episode might be the one nobody expected—and the one a lot of people need to hear. Kimberly Cunningham joins me to discuss her book Great Sex Never Gets Old: Health, Hormones, and Having It All After 40, and to make the case that sexual wellness isn’t separate from health. It is an indicator of overall health.

If you’ve been confused or scared by what you’ve heard about GLPs, this episode is for you. Kimberly Cunningham explains why the bad press comes from bad prescribing, how blood sugar connects to brain health, and why millions of women with PCOS may have been fighting the wrong battle their entire lives.

Western medicine excels at trauma and acute care—if you get hit by a truck, you want that on U.S. soil. But when it comes to longevity, independence, and quality of life across the full lifespan, the conventional model falls short. It’s built on what Dr. Kimberly Cunningham calls “name, blame, and tame”—diagnose the condition, prescribe a pill, manage the symptom. Functional medicine asks a different question: why did this go wrong in the first place, and can we fix the root cause?
