The five Pure Abs & Arms 10-minute workouts, which can be done all together or separately, are focused and challenging. But at just 10 minutes each, they are manageable even at their most intense, and designed for the best results. The disc, which comes with a nice long resistance band, mixes upper body workouts with great ab movements. The viewer will also want a set of dumbbells for one of the arms workouts; 5 pounds is plenty challenging, because there really is no rest between reps. Instructors Fred DeVito and Elisabeth Halfpapp give clear, encouraging instruction, solely as voice-overs, which enables them to focus on demonstrating proper technique during the workouts themselves. The resistance band makes increasing (or decreasing) the intensity easy, and the high-energy repetitions mean the viewer should feel and see results quickly. Many of the movements are inspired by traditional weightlifting, Pilates, and yoga, but the instructors combine actions in unusual ways to cross-work muscle groups--and to keep things interesting. For working every muscle group in the arms and abs, Pure Abs & Arms is an enjoyable, flexible routine that is also a lot of fun. --A.T. Hurley
