If someone paid you to quit smoking or lose weight, would you? Some companies are banking on it.

The way is works is pretty simple. Some companies call it "Wellness-Based Incentive." It's pretty simple: make healthy choices, and you'll pay less for your health insurance. You could even win prizes!

Tracy Cleveland's job as a purchasing manager at Children's Hospital of Wisconsin is pretty sedentary.

So sedentary, in fact, he never expected to find himself working out every morning, or training for a marathon.

His job gave him the incentive: a financial break on his health insurance.

Children's Hospital offers it to every employee. It's part of the hospital's "Healthy Steps" program.

Staci Benz, the Benefits Manager at Children's Hospital, explained the program to us.

"We do offer incentives and prizes, fitness equipment and other things to encourage people to participate throughout the year," Benz said.

It's a growing trend. Nearly a third of companies are offering "wellness incentives" to their employees. Get fit and you save money on health insurance.

The incentives are working for Quad Graphics employee Kathy Gumbert.

She spoke candidly about her lifelong struggle with her weight.

"I've lost a ton of weight in my life... Lost it gained it, lost it, gained it," Gumbert said.

Until "Lean You," the wellness-incentives based program at Quad Graphics, came along. That was the kickstart she needed to make life changes.

"This was the first time I had a personal incentive to just get it done. I knew it was going to get more difficult the older I got. This was just the time," she said.

Quad offered Kathy the tools she needed: use of a fitness center, help from a dietitian, and perhaps the greatest motivator of all, money. By getting healthier, she saved hundreds of dollars on her health insurance.

Dr. Ray Zastrow, the president of Quad Med, was instrumental in getting "Lean You" started. He said the incentives have to be big enough for employees to consider.

"They're thinking about it, they know they should quit smoking, know they should exercise more, then we put a little bit of money on the table and that's what gets them over the hump and gets them involved," he explained candidly.

It's working. Nearly three-fourths of Quad employees have signed up for "Lean You." The financial incentives seem to help, and there's a financial incentive for the company as well.

"We have to find a way to rein in health care costs, and this is the way to do it," Dr. Zastrow said.

Kathy Gumbert is 70 pounds lighter, and loving life.

"Money is one thing but we can all earn money, we can't all earn health though. That's something we have to do for ourselves. They just give us the means to do it," she told us.

While Kathy enjoys her new lease on life... Children's Hospital employee Tracy Cleveland is in training.

"I will hopefully compete in my first marathon this fall," he said. "I have all new clothes, I've lost about 6 inches off my waist, over 40 pounds."

Early disease detection is another plus of wellness-incentive programs. Quad's mandatory physicals turned up three cases of cancer. All found so early... doctors were able to cure every case.
