I really like Shelley McDonald as an instructor.
The workouts are short, and intermediate, but they're nice as a warm-up to weight work, or when you want a lighter workout, or you're not in the mood to workout, but want to do something, or when you just want to move and want something very simple. you can also string them together for a longer workout.
I like the cardio workouts. Walmart has a two-pack including pilates and 'buns, hips and abs" or something like that. The 'b/h/a' workouts are actually cardio workouts with a bit of toning thrown in.
I didn't like the kickboxing workout when I tried it (Netflix has this one, and maybe some others), because some of the moves were not sequenced well, and the 3 workouts were very repetitive).
