Repetitions is a fitness science podcast for people who actually want to know what works. Two AI hosts, Jack and Daisy, read the studies, run the numbers, and cut through the noise so you don't have to. Jack brings the gym floor reality check. Daisy brings the meta-analyses and the receipts. Together they break down everything from creatine dosing to looksmaxxing trends to sleep optimization, calling out the bad science without picking fights with the credentialed voices who got things mostly right. No supplements to sell you, no affiliate codes, no hot takes for clicks. Just real research. If you have ever wondered whether bone smashing actually works, whether your pre-workout is doing anything, or whether you should be tracking REM sleep on your watch, this is the show that gives you the answer the literature actually supports.© 2026 Tamez Labs.

  • 10-20 sets per muscle: the volume sweet spot that stops working

    10-20 sets per muscle: the volume sweet spot that stops working
    2026/06/01
    Turns out the 10-20 sets per muscle per week rule that took over every gym conversation since 2017 is real, but it was never meant to be your number specifically. Schoenfeld's meta-analysis nailed the population average, then a 2022 review came in and showed some people plateau way before 20 sets while others can push past it without burning out, depending on recovery, stress, and training history. The science is basically saying use the range as a starting point, then watch how your body actually responds, because the research found the sweet spot, not your sweet spot.

  • Mewing doesn't reshape adult skulls: what actually changes your face

    Mewing doesn't reshape adult skulls: what actually changes your face
    2026/05/25
    The AAO officially called it in 2019: pressing your tongue to the roof of your mouth does nothing to reshape adult bone, because the palate finishes fusing in your early twenties and stops responding to tongue pressure entirely. The jawlines you see in mewing before-and-afters are almost always just weight loss, better posture, or a different camera angle. Hundreds of millions of views later, the biology has not changed, only the audience believing otherwise has grown.

  • 0.8g per pound of protein covers all muscle growth: beyond that is waste

    0.8g per pound of protein covers all muscle growth: beyond that is waste
    2026/05/21
    49 randomized controlled trials and nearly 2,000 subjects later, researchers at McMaster University found your muscles stop responding to protein at 0.73 grams per pound of bodyweight per day, not the one gram per pound that gym culture has been preaching for decades. For a 180-pound person, that gap means eating roughly 47 extra pounds of protein per year with zero additional muscle to show for it. The one-gram standard was never backed by dose-response data, it just got laundered through bodybuilding forums and supplement marketing until everyone forgot to ask where it came from.
