Her Commitment Strategy
"Bob taught us that you don't have to exercise two hours a day to be healthy. You just have to be consistent."
Her Special Workout
"A fellow teacher at my school started a running club, which is a fun break from my usual indoor regimen."
Her Changing Shape
"In the past couple of weeks, the scale has said I'm not losing any pounds. But my body says I'm getting fitter."
Her Best Tip
"Keep it real. You can't say, 'I'm never going to eat French fries again,' because that mentality isn't sustainable. If you're sitting by the pool and you want a piña colada, by all means, you should have it."
