The dance workout known as Zumba may not be what gets people up and moving in the New Year. It's fallen off the American College of Sports Medicine's fitness trend survey. Here's a look at what will be big in 2014.
Rebecca Williams is pushing a 160-pound sled across the room as fast as she can six times in a row.
"Feels like you're pushing a car," she said.
She and her classmates at Volt Fitness in New Jersey get a short break after they push, but still...
"I'll be feeling this all day!" Ingrid Castro said.
This is a type of high intensity interval training, short bursts of activity doing almost anything followed by a short rest. And for the first time ever, high intensity interval training tops the list of the American College of Sports Medicine's fitness trends for 2014.
Neal Pire is a personal trainer who designed the workout to burn more calories than you eat.
"If you can pack in as many calories burned during a training session as you can, the total calories burned are going to equal calorie deficit," Pire said.
And that's what leads to weight loss. Pire's class also incorporates training using your own body weight, the second top trend for 2014. He says all the back and forth, and up and down with minimal equipment makes exercise simple.
"Simplicity really makes it easy for people to get started," Pire said.
Williams was looking for a no frills workout.
"I see results and it's worth it," she said.
In her first four months, she lost 30 pounds.
Nearly 4,000 fitness professionals participate in this "top trends" survey. The survey is in its eighth year.
