Most of us grew up hearing that we should warm up with a stretch. Strike and hold a pose, such as touching your toes, for 30 seconds or more, we were told, and you’ll be looser, stronger and injury-proof.
But anyone who follows fitness science knows that in recent years a variety of experiments have undermined that idea. Instead, researchers have discovered, this so-called static stretching can lessen jumpers’ heights and sprinters’ speeds, without substantially reducing people’s chances of hurting themselves.
Shawn Arent, director of the Center for Health and Human Performance at Rutgers University, explains why you shouldn’t stretch before you start your workout.
