Giving somebody some advice how to get fitter? First of all, if you want to get fitter you shoud change your diets. I suggest eating healthy food such a lot of vegetables,fruits and fish.If I were you I would stop eating fast food and tried to avoid consuming products with loads of sugar. I recommend having six meals during the all day. The nutrition is the most important thing on the way to get fitter. 70 per cent depends of diets and 30 per cent depends of exercise so take up gym or do exercise at home. The best way to burn out fats is cardio training bacause it increase your heart rate up for 80 per cent. I advise you to practise doing exercise 4 days per a week. In spite of keeping with all this tips, do not expect results soon. The results will have come in one month. I wish you luck.
