Why would you want to kill such a child? Where is your heart? Where is your conscience?

Did you know? Your calf has a muscle that helps pump blood back to your heart. It’s called the soleus, and it’s part of your peripheral heart. When it contracts, it squeezes the deep veins in your calf and pushes blood up against gravity. Valves stop it falling back. But if you sit still all day, this pump sits idle while blood pools in your legs. Mind you, standing calf raises won't fully challenge it. With the knee straight, the gastrocnemius (the muscle on the surface) is free to share the load, because it crosses the knee. So the soleus always gets help and never works at its limit. But if you bend the knee, that flips. A bent knee shortens the gastrocnemius until it goes slack and can barely produce force. Also called ‘active insufficiency’ in exercise science, where a two-joint muscle, shortened at one end, drops out of the movement. So the gastroc switches off, and the soleus, which only crosses the ankle, has to carry the whole thing on its own. That's why the best way to hit it is a bent knee: seated calf raises, or this deep squat version. It’s nearly 80% slow-twitch, so it loves volume and barely fatigues. Sustained work here has even been shown to improve blood sugar control for hours. Train it deep, slow, and often.

A mother cow only produces milk for her calf. Indian dairy farmers using a practice called ‘Khaal baccha’ (‘skin baby’) where a male calf is starved to death and the flesh is removed from its body and stuffed with hay. via @alsaceanimalsave IG #dairytruth

Why are lions still called “King of the Jungle”? They literally scatter the second a real giant like an elephant walks up. Hard to look royal when you're running for your life!

Everytime a begginer throws a calf kick at me i stop and say that check would have fucked your shin. Throw a proper low kick or if your a calf kicker, set it up properly. Any decent thaiboxer will check them too hard. This is why i fully stop. Fuck that
