How do you build up your calves?

[chizler]

for upper legs, do squats
for calves, I learned this from a friend of mine. He is an endurance runner. I was running with him one day and he told me that I was running all wrong, I was running flat footed. He told me to run on the balls of my feet only, dont let my heels touch the ground. I did, and it felt more natural, it was a little easier. Until after I was done.
My calves were so fried, I could hardly walk the next day.
From then on, that's how I ran. now my calves are a lot stronger.
try it,

i just tried this, it worked great my calfs are burning a lot
