This week: how a short workout really works

Don't have time to work out? Researchers have developed a workout that blends strength training with cardiovascular exercise – and it takes just 7 minutes.

Upstate exercise physiologist Carol Sames says the workout was created after asking whether the time could be decreased and the intensity increased to still yield benefit.

“That is essentially what this workout is about. It’s about interval training, which has been around for years, but just packaged slightly differently,” Sames said.

To get the most benefit, Sames says people ideally would do two or three of the 7-minute workout cycles. She goes over the moves that make up the workout this week on the show.

Also on this week's show: two programs designed to improve the health of women and babies.
