Though she looks nothing like Ghengis Khan, Jen Dunbar is building an empire. Its outposts are made of muscles resting on a foundation of knowledge, and it exists to promote an active lifestyle filled with motivation and self-confidence. As an exercise physiologist, Dunbar studies the latest kinesiology research every day, looking for evidence-based ways to melt fat and boost muscle mass. She also draws from years of lacrosse coaching and four personal-training certifications to help her clients to perform at their peak, whether they're running a marathon, slimming down for a wedding, or preparing for the national hopscotch championships. Filled with strength training, sprinting, and constant encouragement, her workouts challenge exercisers to push themselves, even if they've never done a pushup before. In addition to training athletes one-on-one, Dunbar leads small-group workouts and online boot camps packed with jumping drills, body-weight exercises, and weight-lifting challenges.
