Big Boned, Big Thighs & the Truth Your Tape Measure Won't Tell You

Midlife Mayhem — Episode Show Notes

Hey there,

Two Instagram posts sent me down a rabbit hole this week, and I couldn't wait to bring it to you.

Post one: a woman says if you can't wrap your fingers around your wrist, you're "big boned" — not overweight, just built bigger. Post two: if your thigh isn't over 24 inches around, you'll apparently live longer. As someone who's trained for 44 years, can squat 200lbs, and still only measures 20 inches on a good day... I had thoughts.

So this episode is a myth autopsy. Both claims have real research behind them — that's exactly why they spread so fast. But both get flattened and distorted by the time they hit your feed. In this one, I break down:

Where the "wrist test" actually comes from, and what it's really measuring (hint: not what you think)

Why your skeleton makes up roughly 12–15% of your body weight no matter your frame size — and why that number barely moves

The real 2009 Danish study behind the thigh circumference claim, and the threshold it actually found (not the straight line social media is selling you)

Why a tape measure can't tell muscle from fat — and why that matters more than the number itself

The one waist measurement I'd actually pay attention to instead

What genuinely protects your bones and muscle in midlife (spoiler: it's not a tape measure)

I also measure my own wrist and thigh live on the mic, so you can hear exactly how the numbers play out on someone who's spent a lifetime training. Grab your own tape measure before you hit play — you'll want to check your own numbers along the way.
