Stretch After You Run, Not Before

Runners have long believed that stretching will give them a longer, smoother stride and reduce their risk of injuries. However, in recent years research has failed to prove either point. Budd Coates and Jeff Galloway say they've never advocated stretching for their beginning runners, and the runners haven't developed injuries. Adds Dr. Lewis Maharam: "A preworkout stretching routine doesn't prevent injuries or improve performance, so there's no reason to do it. The time to do your stretching is after your run, or even later in the evening." Stretch (without straining) your calves, quads, and hamstrings for 10 to 15 minutes.
