Could Strong Legs Help You Live Longer?

One of the things I love about working with clients is how many interesting health conversations come up.

Recently, I admitted to a client that I hate lower-body workouts… especially squats. I have to negotiate with myself through every set: Come on, only three more. Okay, only two more. She laughed because she does the same thing, but for a very specific reason: she had read that the size of your thighs may be connected to how long you live. She’s in her 60s and can still squat all the way down, butt to heels, without a problem.

What the Thigh Circumference Study Found

That sounded just strange enough that I had to look it up. And yes, there really is a study behind it. In 2009, researchers followed 2,816 Danish adults ages 35 to 65. They measured each person’s right thigh directly below the gluteal fold, then tracked cardiovascular disease for 10 years and deaths for 12.5 years. During that time, 403 participants developed cardiovascular disease and 412 died.

The surprising finding was that people with thighs measuring below roughly 60 centimeters—about 23.6 inches—had a higher risk of heart disease and premature death. Above that point, larger thighs didn’t appear to offer any additional benefit. A 2020 BMJ review later found the same general pattern: larger thigh circumference was associated with lower overall mortality, although only three studies had enough thigh data to be combined.

Before everyone reaches for a tape measure, that number is not a personal life-expectancy test. These studies found an association, not proof that making your thighs bigger will make you live longer. Thigh circumference also includes muscle, fat, and bone; it doesn’t tell researchers exactly what the thigh is made of. Smaller thighs could reflect lower muscle mass, less lower-body fat, nutrition, illness, activity level, or a mix of factors that are hard to separate.

Why Strength May Matter More Than Size

So no, my client did not make me love squats. I’ll probably keep bargaining my way through every set. But she did give me a better reason to finish the last few.

Thigh size alone cannot tell us how long we’ll live, but maintaining strong legs and staying mobile may help us live those years with more freedom, and that feels worth two more squats.
