I want to get into shape for a charity ride at the end of June and am trying to shed the extra saddlebags left behind by the Thanksgiving Turkey & Christmas Cookies. Is losing 15 lbs in 22 weeks a reasonable goal? I am doing a pseudo-weight watchers program (low fat, high protein & fiber) and hitting the gym/trainer at least 2 times per week. Am I biting off more than I can chew?
