Is there a book on how to lose belly fat? I have been going to the gym. I have been working out until I am ready to drop. I have trimmed and toned my legs, my arms, and my buttocks. However, my exercising has had no effect on my mid section. I still have the spare tire that I started out with. I need to know which exercises to do. I need to know which exercises will target my mid section. I need to find exercises that will effectively help me lose the extra weight and tone my abdominal muscles.
