The Crouch Launch
Why do runners crouch at the start line?
Watch a sprinter at the starting line. They're not standing tall like you'd expect. They're crouched down low, hands pressed to the ground, one knee almost touching the track. It looks uncomfortable. So why do the fastest runners in the world start a race looking like they're about to crawl?
The answer is physics. When the starting gun fires, the runner's job is to go from zero to top speed as fast as humanly possible. And speed comes from force—how hard you can push against the ground. The ground pushes back with equal force, launching you forward. The crouch is designed to let you push harder than any other starting position could.
