Senior Associate Editor Amanda MacMillan blogs weekly about fitness and health news, and is always up for a new workout challenge: She’s climbed a waterfall in Costa Rica, hiked the tallest mountain in the Northeast United States, and tested plenty of exercise fads right in her Brooklyn apartment. (Current obsessions include the as-seen-on-TV Iron Gym for strength workouts and a stability ball as a desk chair.)
She ran her first half marathon in May, 2008, and completed her first Olympic-distance triathlon in July 2009. Follow her on Twitter for updates on what she’s up to next.
