Karin Holben considers herself a skeptic, but not when it comes to her new workout.
"I think I've missed one day since I started coming, and I feel amazing," said Holben.
She's become a regular at Goga, which stands for Get On, Get Active.
It's based on using a whole-body vibration machine and is billed by some as the "no work" workout.
"As the platform moves, it throws your body off balance just a little bit so your muscles contract, so you get about 4 to 6-thousand muscle contractions in a 10 minute session," said Lorie Scheer of Goga Studios. "It helps to improve bone density, it's kind to the joints, there's no impact."
Goga claims to produce similar results to an hour at the gym, with an emphasis on toning and strengthening.
"The biggest part for me which totally thrilled me was I lost an inch off my hips and my waist and my chest, in a month," said Goga fan Lori Jamrok.
Some Goga participants also say gives them more energy and helps them sleep better at night.
Whole body vibration is already recommended by some doctors and trainers to help improve balance in older adults and reduce bone loss. Experts say Goga shouldn't replace other aerobic and strength training exercises, but may be worth a try for exercisers looking to "shake up" their workouts.
Goga studios are beginning to open across the country. A monthly membership costs $49.
