Scientists Discover: There's No One 'Perfect' Way to Run Super Fast!

Scientists just figured out that the world's fastest sprinters don't all run the same way—they each have their own special style that works for their body! Instead of one perfect running technique, speed comes from mixing your unique body shape, how your muscles work together, your strength, and lots of training. This means you could become a champion sprinter even if you run completely differently from everyone else—how cool is that?
