Sprinter's Speed Machine
How do athletes run so fast?
Watch a sprinter explode off the blocks — legs blurring, arms pumping, whole body a machine built for one thing: GO. How do they move that fast when the rest of us are huffing after the bus?
First, the legs. Sprinters don't just run — they attack the ground. Every step slams down with hundreds of pounds of force, and the track pushes back just as hard. That push is what launches them forward. More force into the ground means more speed coming out.
