WHAT SHE DOES: [Jena Simmons] had struggled with weight problems her whole life and weighed almost 300 pounds in 2004, when she decided to have gastric bypass surgery and ended up losing 135 pounds. About six weeks after the surgery, she joined Curves to get some exercise and tone up. "fit Curves, you can work out at your own pace, which is good and bad. But I needed more motivation and someone to be accountable to, so I started going to Jazzercise with my daughter in 2005." Jena also participated in a group walk to benefit cancer. "I finished tenth from last, but I finished it and was very pleased with myself, " she said.
