Experts: Don’t stretch before exercising

LONDON (AP) — Want a better work-out? Then don’t stretch beforehand, some experts say.

Many people take it for granted that they should start their exercise routines with some stretching on
the spot, perhaps hoping it will loosen them up for their work-out. Most fitness experts now agree this
kind of static stretching before exercise is not just counter-productive, but potentially harmful.

Traditional stretches, like when people bend over to touch their toes or stretch their legs on a fence,
often cause the muscles to tighten rather than relax — exactly the opposite of what is needed for
physical activity.

Experts say it is like extending a rubber band to its limit. When people stretch to the maximum, they are
more likely to pull a muscle.

“We have developed this idea of static stretching at exactly the wrong time,” said Kieran O’Sullivan, an
exercise expert at the University of Limerick in Ireland, who has studied various types of stretching
and their impact on athletes.

When you stretch before exercising, your body may think it’s at risk of being overstretched. It c
ompensates by contracting and becoming more tense. That means you aren’t able to move as fast or
as freely, making you more likely to get hurt.

O’Sullivan said stretching helps with flexibility, but people should only do it when they aren’t about to
exercise, like after a workout, or at the end of the day.

“It’s like weight training to become stronger,” he said. “You wouldn’t do a weight session right before
you exercise, and you shouldn’t stretch right before either.”
