Kim Martin reached her breaking point when she realized she couldn't even sit on the sofa with her youngest daughter.
She always had struggled with her weight, which always had fluctuated, and having three children hadn't stabilized it. But she knew it was time for a change, she said.
"At my heaviest, I was probably very unhappy, even though people can't necessarily tell," Martin, of Lincoln, said. "But if you really look at my eyes in the pictures, you can tell the unhappiness, if somebody's been in that same place."
Over three years, Martin lost more than 100 pounds, and as she pursued a healthier lifestyle, she discovered Zumba, the fast-paced dance workout that's growing in popularity around the world. Her love of Zumba, and of helping people get healthy, led her to quit her job, become a Zumba instructor and open Total Body Infusion, her fitness studio at Seventh and Van Dorn streets.
