You're an adult now. No longer should you use baby fat as an excuse. (And actually, babies are no longer expected to be fat.) The good news: you can deflate your "baby fat" fat cells with proper diet and exercise. It is important to have a regular exercise routine - strength training is important, too. But for weight loss, aerobics is the way to go. Jogging and power walking are excellent calorie burners. You may also try the treadmill, the stair master or spinning. In addition to exercise, diet is crucial for weight loss. Exercise helps burn calories, but diet controls your weight. If you cut fatty foods (fried and processed foods) and increase fruit, vegetables, grain and protein, you will automatically cut calories.
