if you feel like people are judging you then I wouldnt consider that to be a great barn to be at. My barn is like a lil family & there are a cpl of us bigger girls there and its never been an issue, I've recently started using weight watchers and I love it. I never feel hungry & it encourages you to eat. I've lost 5 pds already and its only been a week. Im trying to only weigh myself every two weeks to give it time to work plus I work at my barn so I count that as my work out as well as my lessons. (with another job no time for real workouts lol ) & that is working just fine. I always count my ride as a workout, because it def is. Don't let anyone make you feel inferior about your weight, because 160 really is not that bad. I can't wait to be 160 lol just concentrate on your love of riding instead of others opinions and eat healthy :) its not so much about counting calories as it is changing your lifestyle.
the love of riding outweighs the fear of falling.
