ALPHARETTA, Ga. -- Karin Holben considers herself a skeptic, but she is sold on a new kind of workout.
"I think I've missed one day since I started coming, and I feel amazing," she said.
She's become a regular at the first studio in metro Atlanta that's dedicated to GOGA, which stands for Get On, Get Active. The key is a whole-body vibration machine.
"As the platform moves, it throws your body off balance just a little bit so your muscles contract," said Lorie Scheer, owner of GOGA Studios in Alpharetta. "So you get about 4,000 to 6,000 muscle contractions in a 10-minute session"
It's designed to produce the same results as if you spent 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 client Lori Jamrock.
Jamrock said GOGA gives her more energy and even helps her sleep better at night.
"Your circulation increases, your lymphatic system is stimulated so your toxins are released," Scheer said. "It helps to improve bone density. It's kind to the joints. There's no impact."
GOGA Studios are beginning to open across the country, and the company cites decades of research that show whole body vibration works.
In the metro area's first studio in Alpharetta, it's catching on.
