Losing weight is all about burning up calories. Diets, routine are all useful for losing weight. But they cannot work drastically on your body. For example, when we accumulate too much weight on certain areas of our body like lower belly, thighs, buttocks etc. we need to exercise to burn the fat from these areas. When we have a diet, it works slowly on the whole body. You cannot expect to tone up your muscles with dieting. You cannot also expect your body to go through a drastic change if you only change your food habits. Yes, they are helpful. But with these routines, you are just making it sure that you are not adding extra fat in your body. But what would happen to the fats that have already accumulated in your body. To burn these already accumulated fats, you have to shake them up, push them hard. For that you really have to push & play hard with exercise.
The experts say that a routine exercise is really helping for burning up the extra calories of your body. When you do cardio, your heart pumps really fast & it causes more calories to burn up. You can start up with small routines of cardio. For example, start with a 30 minute routine. No matter what kind of cardio you do., you can do treadmills, cycling, swimming or other cardio exercises.
Then you need to increase the time limit slowly & 90 minutes of cardio everyday is really a cracker to help you to burn the extra fats of body & maintain a healthy weight. Also they will help you to tone the muscles & working on certain areas of body which have gained more fat.
