The new 7 Minute Workout - does it work?

(WJBK) - Have you heard of the 7 minute workout?

Some apps and websites provide 7 minute workouts they claim with work your entire body in just that little amount of time. FOX 2's Deena Centofanti put them to the test.

Barry Franklin, Beaumont's Director of Preventive Cardiology and Cardiac Rehab say he gets the appeal of them.

"Everybody's trying to cram more in less," he says. He says -- it works.

"There's lots of studies that show, in general, the higher you work out the shorter the duration. So, if you're working out really hard for those seven minutes, yes, you can gets lots of benefits," he adds.

Dr. Franklin says you probably won't lose a bunch of weight exercising for only seven minutes a day, but there are benefits.

"There are studies that show it improves your fitness to a greater extent; it improves your muscular strength to an extent; it improves your vascular tone to a greater extent," he says.

One thing, though, Dr. Franklin says those are this intense 7 minute workout is not for everyone.

"It's not the kind of workout I recommend in older people, older people with cardiovascular disease, with diabetes, because that high intensity exercise can also trigger heart attack, sudden cardiac death," he says.

If you're in the right age group and want to give it a try, you can search for an app in your app store or do an online search to find one on a website.
