Cycling makes you Run stronger and longer.
So finds the latest study in the Journal of strength and conditioning Research. Runners who did three weekly cycling workouts – Consisting of six 10-second all-out sprints alternated with 30-to 80 second rests- along with 25 miles of running, improved within two weeks. Those who rested for 30 seconds between intervals trimmed their 3K time by up to 7 percent, and those who rested for 80 seconds boosted their endurance and power. Researchers say such cycling helps you push harder than you would by just running more, plus it reduces the pounding on your body and slashes your workout time.
In short words : One cycling sprint session takes as little as three- and a-half minutes but gets you big running speed.
