The foremost step to getting an attractive body is to get a good diet. Eating healthy foods will help you maintain the proper weight for your height and age, as well as provide the energy you need to exercise regularly.
To improve your overall health and fitness, start exercising at least thrice a week for up to 30 minutes each set. Try diverse types of physical conditioning so that you don't get bored: lifting weights at the gym, jogging outside, or playing sports with friends are all good ways to get fit.
