Dear Stacy,

I have 80 pounds to lose. I've been doing Weight Watchers along withb daily workouts five times a week for several months now. I can see a big difference in my muscles, but I'm not losing weight and I still have a lot of cellulite. If I added a 30-minute walk three times a week, would that help?

Don't get discouraged! Remember that muscle weighs more than fat, but it takes up less space, so you can lose inches without actually dropping pounds. I personally don't get on a scale — I just go by how my clothes fit. So keep up with everything you're doing, and yes, add that walk and other forms of cardio to give your weight-loss efforts a boost. Walking will fire up your metabolism and help you burn more fat and calories. And be sure to drink lots of water.

Dear Stacy -

I love using the stair-climbing machine, but I feel like my thighs are getting bulky. How can I work my legs and burn calories without getting too big?

If you're worried about working out on the stair-climbing machine too often, why not mix it up? Variety helps keep you motivated and also tones your body more effectively than if you worked out in the exact same way every day. That's because when you do the same routine day in and day out, your muscles grow accustomed to the motions and stop feeling challenged. By doing a new activity, you will be forced to concentrate instead of slipping into old habits.
