Yeah, BMI is not the most accurate. It's hard to lose the fat around the waist, try a change in diet. Lower your carb intake (I cut out the obvious carbs, bread, pasta) and vary your workout (bike, elliptical, running, weights, yoga) in both light and high intensity/ cardio and wt train. Basically you want to shock your muscles so they don't get used to one particular task. It also makes exercise more interesting for you too.
