Form Fixers

As a runner, there’s no better feeling than hitting the pavement or trail. And whether you’re signed up for an event or not, consider this: even the average runner (oh, hi) should be working both sprints and endurance runs into their routine for serious pay-offs.

If you’re, say, a marathoner trying to hit a PB, speedwork will make you faster. (Plus, studies show that sprints can reduce body fat, if changing body composition is a focus for you.) Prefer fast and furious? Know that longer-distance cardio is powerful for overall wellness, too. Plus, training for a marathon, even at low intensity, reduced vascular age (essentially, the health of your arteries) in people by four years, according to a University College London study.
