Remember there are three equally important components in a true physical fitness lifestyle:
Nutrition: This is no secret and there are no quick fixes. This is the stuff you learned in the third grade. Balanced meals and food from the food groups, along with PROPER PORTIONS, is still the way to go!
Aerobic Activity: This is ANY activity that is done for a minimum of 20 minutes that elevates your heart rate. It can be biking, jogging, aerobics classes, hiking or any number of other things. I recommend that you do some type of aerobic exercise at least four times a week. This activity teaches your body to burn calories more efficiently and exercises the most important muscle in your body, your heart.
Strength training: This is where your "body shaping" can take place. Making your body strong with weight resistance can do wonders for you. Using weights to shape your mucles can vastly improve your symmetry.
Begin some sort of aerobic activity (even if it’s just a short, brisk walk) and try the following workout routine for a couple of weeks and see if you don’t feel better. Don’t forget to pay attention to your eating habits!
