Almost every workout should end with a little extra core work and some stretching. Our latest Class FitSugar takes you through a standing ab workout, planks, and lying ab work, and we follow up these exercises with some stretches to lengthen all your hardworking muscles. Try this video on its own or after our active warmup and cardio workout, 10-minute lower-body workout, or upper-body video. Taken alone or together, these workouts will help you get fit for 2013.
