Los Angeles, Oct 10: Model Ashley Graham has hit back at her critics, saying she doesn't exercise to lose weight and loves her body. The 29-year-old shared a number of videos of her Sunday workout and she couldn't believe that some of her followers didn't like her fitness regime, reports dailymail.co.uk. "Every time I post a workout video I get comments like, 'You'll never be skinny so stop trying' and 'You still need your fat to be a model'," she wrote on Instagram. "I workout to stay healthy, feel good, get rid of jet lag, clear my head, show big girls we can move like the rest of them, stay flexible and strong, have more energy. I don't workout to lose weight or my curves, because I love the skin I'm in," she added.
