Your legs are secondary hearts.

Yes, I’m absolutely serious.

There are 1 way valves in your leg veins. Veins are the ones that carry blood back to your core, and eventually your (primary) heart. These valves only allow your blood to flow towards your core.

When you flex the big muscles in your legs, you end up compressing those veins. Because of the one-way valves, this pushes the blood in those veins against gravity, towards your core. When those muscles relax, those veins expand, and can be re-filled.

Those one way valves, combined with the flexibility of the veins, allows your large leg muscles to drive blood against gravity, back to your core.

So I’m totally serious. Your legs are secondary hearts, and flexing those big leg muscles pumps blood back to your core.
