Don't quit just because you're not seeing the results you want. There's a LOT more to gain by continuing to ride your bike, and exercise in general, then just smoothing out the bumps.

Four years ago I was about 35 lbs. overweight, sluggish, tired, weak, and my legs were like two pillars of jello. I began walking and eating healthier, then we bought a treadmill, and last spring we bought bikes. This past year, we rode a few times during the week, and longer on the weekends. In the past 4 years I s-l-o-w-l-y lost 50 lbs. (about 1 to 1-1/2 lbs./month average), I feel TERRIFIC, and my legs are taking shape! They are like new legs! There is still cellulite especially in the back of my thighs, but I feel so good, my endurance/energy/strength are as good if not better than 20+ years ago, and I'm having so much fun on the bike that I don't want to quit. The cellulite will never go away -- I'm fair-skinned which makes it show more -- but it's not nearly as important as your overall fitness which includes strength and endurance. There are many women who are "thin" but not fit and strong; it's much more important to be fit even if there are some bumps.

BTW, I'm almost 52 years old.

Hang in there -- don't quit! Focus on making exercise part of your lifestyle, not using exercise just to lose weight. If you do it right, you'll gradually lose the fat and build muscle and look (and feel) better overall.
