Yet another study showing similar muscle growth when using heavy vs light loads. The evidence is overwhelming on the topic: loading ranges of ~5 to 30 reps build muscle equally. Very nice study design from the lab of @mackinprof 💪 physoc.onlinelibrary.wiley.com/doi/10.1113/JP…

Upcoming Postdoc Position! With Chris Nelson’s lab at U of A, we are looking for a fully supported 2-year postdoc to work on muscle gene editing and detection of gene doping in vivo. If interested, email myself and Chris: kmurach@uark.edu and nelsonc@uark.edu #myotwitter

We’re hiring! Baylor's Department of Health, Human Performance, and Recreation invites applications for a TT Assistant Professor with expertise in clinical, applied, or translational health related research. Reach out if you are interested. apply.interfolio.com/172776

🌿 Food as rejuvenation medicine in action: Thymol, the compound that gives thyme its delicious aroma, delayed epigenetic aging in skeletal muscle by about 20% in fast-aging mice. It preserved strength, reduced muscle loss, and boosted cellular cleanup + energy production. #Rejuvenation #EpigeneticClocks Gabriele Civiletto, Philipp Gut (2025) Herbal terpenoids activate autophagy and mitophagy through modulation of bioenergetics and protect from metabolic stress, sarcopenia and epigenetic aging.

GLP-1 drugs are game-changers—but the game doesn't end with pounds lost. Without strategies to preserve lean mass, you risk compromising metabolism, function, and long-term success. That’s why building muscle—and safeguarding it—is a critical piece of the GLP-1 story, not just a footnote. weightlossand.com/how-to-keep-th…
