The four-time Olympic sprint champion Michael Johnson begins our lesson in how to run faster with an unexpected discussion about cars and cowboys. “If you want your car to go faster, you push the accelerator,” says Johnson. At 47, he is still lean and athletic in a tracksuit. “When you sprint, think of your arms as your accelerators. Your arms drive your legs, not the other way round.”
As i have preached to my athletes time and time again, the speed of your arms dictate the speed of your legs. People who say the legs are the main attribute for speed are way off the finish line.
