NORTH TEXAS (CBSDFW.COM) – What does it take to get in shape? Some experts say just 60 seconds of intense exercise is enough.

Yes! One, full-blown, explosive, minute of exercise has the same effect of a 45-minute moderate workout.

“It could be a burpee, it could be jogging in place, it could be high leg lifts,” said Larry North of Larry North Fitness. “Do it like you’re being chased by a grizzly bear.”

The study published in Plos One suggests that 60 seconds of intense moves into your workout may be the key to getting fit.

North has told his customers for years about interval training and now science backs him up. He’s pleased that scientists are studying it.

CBS11 Anchor Kaley O’Kelly did her own workout with North and his assistant Kathleen Iliff. She did 60 seconds of burpees, then rested for about 2 minutes. Another minute of jump squats, resting for another 2 minutes ending with a minute of belly busters followed by yet another resting period. North said you can do them anytime of the day for however long you want, adding that people don’t have to work out as long as they thought.

“Working out 3-4 minutes at a time can help you stay fit,” he said.

North said short bursts of high intensity workouts help with blood flow because there’s more oxygen in your system. It also helps build muscle. “It’s a combination of everything!” he said.

But not everyone is sold on the idea.

Exercise physiologist, Dr. Scott Weise worries that people might think this is sort of interval workout is enough for total fitness.

“Somebody who really thinks they’re going to do one minute, and all of a sudden change the shape of their body and be a new a person, it’s not going to happen,” Weiss said. “I wish it did.”

But there’s one thing everyone can agree on!

“I always say the shortest workout I ever did with the least amount of equipment I ever had was still better than the workout I didn’t do,” North said.

He believes for people trying to lose weight, diet and portion control is equally important. The 10 minute workout could include 30 seconds of two or three intense exercises like burpees, squat jumps or mountain climbers. He also believes warming and cooling your body before the workout is as important as the actual workout itself.
