Following this exercise plan for a three months will definitely yield positive results. However, to maintain a fit body, one must also be careful about diet. Your food contributes to your weight in a large way. Thus, strictly avoid carbs, fried food items and all the junk food. Replace these with healthy fiber food, fresh fruits and whole grains. Losing weight isn't an overnight process, but one that demands dedication to the cause and a wholehearted effort.
