Don't forget to drink plenty of fluids, too. Regular exercise will help. But don't try to do too much too soon. Start slow and set realistic goals. It'll take time, so don't be discouraged if you don't see results right away.
Consistency is the key.
When starting an exercise program, don't do too much too soon. Begin slow and set realistic goals. But stick with it. The more consistent you are, the better. And to keep from getting bored, try a variety of activities.
