In this episode of The Rundown, Dr. Jordan Feigenbaum and Dr. Austin Baraki dive deep into the latest data and breaking news spanning strength, longevity, and health policy. They kick off the discussion by analyzing world record powerlifting data to dissect the perennial sumo versus conventional deadlift debate and the impact of specialized equipment.
Next, they tackle controversial new science on exercise intensity, revealing that vigorous physical activity may be far more efficient for disease risk reduction than the traditional 1:2 ratio suggests. They examine a new, complex consensus statement from the ACSM on exercise intensity domains. Finally, the hosts analyze new clinical data on the anti-obesity medication semaglutide (Ozempic/Wegovy), assessing its impact on muscle function during weight loss, and they weigh in on Chinaās new mandate requiring influencer certifications for sensitive topics, as well as the critical issue of lead in protein powder.

The episode begins with a deep dive into the deadlift, inspired by a video of an impressive 420 kg (924 lb) pull on a stiff barāa significantly harder feat than lifting the same weight on a flexible deadlift bar. The hosts use this to frame the differences between competition equipment (stiff bar vs. deadlift bar) and lift style (sumo vs. conventional).
The data suggests a substantial deltaāas much as 67.5 kg (148 lbs)ābetween the heaviest pulls on a deadlift bar versus a stiff bar. This difference is attributed not only to the bar's smaller diameter (improving grip) but also its increased deflection (reducing the initial height of the pull).
Dr. Feigenbaum emphasizes that the benefits of lifting more weight with a specific style or equipment are concentrated on that lift alone. Training specificity is key: a style that allows you to deadlift more does not inherently make your legs stronger for a leg press, running faster, or jumping higher. Therefore, outside of competition, stylistic preference and injury risk management should dictate your choice. For instance, determining Should I conventional or sumo deadlift for low back pain? is a highly individualized choice based on mechanics and comfort, not maximizing absolute load.
Analyzing the top 100 raw deadlifts in the IPF (a tested federation using stiff bars) reveals that the sumo versus conventional deadlift debate is not a "slam dunk" for either style. The results are split: 52% of top men use sumo, and 48% use conventional. For women, it was 65% sumo and 35% conventional. This data suggests that elite lifters, who certainly experiment, often revert to the style that works best for their unique anthropometry and leverages. The process of progressive resistance training older adults or any new lifter requires a coach to act as a "guide to the Sorting Hat"āsampling different styles and assistance exercises to find the technique that unlocks the individual's highest training capacity.

The hosts scrutinize a new analysis that calls into question the long-held public health guideline that one minute of vigorous physical activity (VPA) is equivalent to two minutes of moderate physical activity (MPA).
Analyzing accelerometer data from over 73,000 adults over eight years, the researchers found the efficiency gap to be much larger than 1:2. VPA was significantly more efficient for disease risk reduction:
The hosts theorize that this massive disconnect may be an artifact of using Metabolic Equivalents (METs)āa highly flawed, one-size-fits-all measureāto categorize exercise. The key insight is that for exercise to be effective, it must be hard enough to count as exercise for the individual. What is moderate for a fit person may be high intensity for a person with COPD.
Instead of relying on confusing MET scores or new, complex jargon like the ACSM's new "metabolic threshold" domains, the most practical tool for the public is the Talk Test.

The discussion addresses the widespread concern about muscle loss (sarcopenia) while using GLP-1 receptor agonists (like semaglutide) for weight management. The SEMALEAN study provided critical data:
Dr. Baraki emphasizes that muscle quality and function are more important than absolute mass changes, especially when excess fat affects muscle quality. The improvement in function directly counters the hysteria about drug-induced sarcopenia. However, for those with conditions like diabetic neuropathy, careful monitoring and strength program modifications for diabetic neuropathy are essential to maximize benefits while protecting tissue.
The takeaway is that resistance training remains the single most important intervention to preserve and build muscle function during weight loss, making these anti-obesity medications and strength training a powerful combined therapy.
The episode concludes with two policy topics:
Protect your health and investment: If you choose to supplement, ensure your protein powder is manufactured in a GMP-accredited facility and is batch tested by a third party for contaminants like lead, cadmium, and arsenic.
