6. Do Plyometrics
Running is a form of jumping. Plyometrics, or jumping exercises, isolate and develop the jumping element of running to make you a better runner. Research has proven that replacing some running with plyometrics enhances running economy and race performance.
As with sprinting, a little but of plyometrics goes a long way. Try doing just 5 minutes of jumping exercises after completing an easy run twice a week, or add a couple of plyometrics drills to your weightlifting workouts.
