Exercise will play as one of the contribution to lose the fats in our body, but it is not alone. if you really want to lose weight or make things happen, you should exercise, change your lifestyle and go on choosing healthy foods. Doing exercise is okay and will help you lose your fats, but those fats will all come back again if you cannot control food, you are selecting food to eat that will make you fat and you still have poor lifestyle. If you still doing all the I mentioned then you lose fats only through perspiration on the day that you work out but still it will come back and come back when you continue do not selecting the food you eat. Better exercise twice a week, drink water, have 8 hours of sleep, eat vegetable, avoid fatty, salty and too sweet foods. Make sure the cardio exercise will become a habit to burn those calories immediately. Exercise will definitely burn fats and it should be the right exercise as well and not those that will strain you.
