Runners are a time-crunched crew. Too often, we push back our speed, fitness, or weight-loss goals when life gets in the way. The focused workouts in these pages are designed to make you faster, stronger, and fitter in however many minutes you can spare.
This article has a good collection of workouts ranging from 20, 30, 45 minutes to an hour (or more) and are broken down into categories.
The first series under the title “The busy runner’s guide to getting faster” is designed to improve speed. The second is called “The busy runner’s guide to staying fit”, which includes a section on stretching with photographs to show you how. This is cool. Then there’s the “The busy runner’s guide to loosing weight”, and finally the article ends with a recommendation for how to schedule a week depending on what the goal is (speed, fitness, weight loss) and how many days a week you can run.
