        Riya is a young dancer who feels contented and satisfied with herself. Let's hear from her. 
 
        Hi, everyone! I am Riya. I suppose I’m really lucky because I don’t put on weight easily. I never tire out in the gym and the only time I work out is when I need something from the top shelf. I tried aerobics several times but I couldn’t keep up with the others. I take my pet for a walk thrice a day though, and that helps to burn off the calories. I usually watch what I eat but I sometimes binge on ice-cream. 
 
       My sister Diya, is a real fitness fanatic. Before she works out she warms up every day with push ups, sit ups, stretches and a jog around the park. She says it’s important to build up good  levels of strength and stamina. I don’t want to overdo it though. A fitness regime like hers would stretch out me!
