New Workout Sweeping S. Fla. Fitness Buffs

MIAMI (CBS4) -- If you get bored with your workout easily, it may be time to switch it up. Interval training classes are more popular than ever and can offer a very intense workout which means more results in less time.

CBS4's Rhiannon Ally tried a class at Orangetheory Fitness.

She also spoke with others in the class to see if they think the classes are worth all the hype.

Andy Westbrook, from North Miami Beach, said he's noticed results from the classes.

"My pants have gotten looser; I've gotten better at the workout. It's better cardio and I feel better overall."

Interval training is not as complicated as it looks. It's short bursts of intense activity with intervals of lighter exercise.

Chan Gannaway from Orangetheory Fitness didn't go easy on Rhiannon.

"You're going to suffer a little bit and then we'll pull you out of it. I don't want you to suffer the whole hour," he told her.

At this fitness center, there are trainers motivating people every step of the way.

"The coaches are there, constantly pushing you, pushing, pushing, and at the end of 60 minutes, you come out exhausted with a really good workout," said Westbrook.

Every participant has a heart monitor strapped on during the whole hour. They say it's one of the things that make this workout so unique.

"I've been in this industry 17 years and I've never seen people want information like now," said Gannaway. "They want to be efficient and don't want to work out 6 days a week if they don't have to."
