Working Out Your Legs Shoots Testosterone Throughout Your Body?

Hi Dr,

I lift weights and I was told by a personal trainer that when you work out your legs, it shoots the testosterone throughout your body. My question is this: can that accelerate hair loss? I asked the pt if it increases testosterone & he said no it just sends what you have throughout your system. Can you tell me if this is something that can accelerate hair loss? Thank you.

Exercises should not increase hair loss, though I do not know if the testosterone shooting through your body occurs from leg exercises. If you’re suggesting that your personal trainer is saying that leg exercises accelerate testosterone and therefore hair loss, I’d believe he’d be incorrect, but there are sources of evidence that suggest he may have a point. In other words, I really don’t have a clear cut answer for you.

The use of steroids or exogenous testosterone will cause hair loss in those who are genetically prone to it (has the genes for balding), but it is not clear that diet or exercise will produce enough testosterone to cause balding.
