The Active Times consulted Stephanie Mansour, health and fitness expert and host of “Step It Up with Steph,” which airs weekend mornings on PBS stations nationwide, to help us put together a comprehensive list of the all-time best exercises for weight loss. We also consulted Harvard Medical School’s guidelines to determine how many calories are burned during some of these routines and gathered information from other popular fitness trainers and the American Council on Exercise for tips on how to do some of the movements properly to get the most out of your workout.
