Five-Hour Plank Record Highlights Benefits—and Limits—of Exercise

Five-Hour Plank Record Highlights Benefits—and Limits—of Exercise

DonnaJean Wilde, who is 61, held a plank for five hours and set a record.

A plank looks still, but many muscles work to keep the body straight.

It can help strengthen the middle of the body and improve stability.

But doing a plank by itself does not fix posture or burn as many calories as activities like running.

Holding it longer is not always better.

If someone gets tired and their form changes, they should stop or take a break.

Beginners can start with short holds and build up slowly.

Other exercises can also help strengthen the core.
