I resisted every single one of these for way too long. These are the 10 hard doses of reality I had to face to get leaner and stronger, protect my metabolic health, and actually feel my best while looking my most fabulous.

Body recomp is real, but it's slower and more nuanced than "calories in vs calories out." It means losing fat while building muscle (or building muscle while losing fat), and that takes a primary focus, sm...

    I spent years thinking losing fat while building muscle was impossible...and that belief was completely sabotaging me.

And the scale was lying to me the entire time.

    In this episode, I'm breaking down exactly why the scale isn't the measure of progress you think it is, what sig...

    JUST. LIFT. HEAVY. We see that all the time on social media. But is that advice actually holding you back?

    In this episode, we're pushing back on the one-size-fits-all approach to strength training. While heavy compound lifts are absolutely valuable, obsessing over low reps and maximal loads means leaving serious gains on the table. We break down the three real drivers of muscle growth — mechanical tension, metabolic stress, a...

    In this video, Cori breaks down the concept of collateral fattening: why extreme weekday deficits cause muscle loss, slow your metabolism, and amplify hunger cues — so that by the time the weekend hits, you're eating ...
