I have to say that I totally give Backside a thumbs up, it's good in so many ways. For a real beginner, you couldn't ask for a better way to start. It consists of 6 circuits, each starting with a short, cardio warmup, then 3 exercises of 3 sets of 3 reps. Jillian has 3 individuals from 3 different BL shows performing the exercises and she 'trains' during the workout, correcting form, offering advice, tips on modifying up or down, and I felt like she was there, training ME personally. I liked that!
Plus, while you never stop moving, each series is performed at a slow, controlled pace so you can really lift heavy if you're a bit more advanced. I definitely got a workout and have a nice burn going now.
The only downside here is that there is no stretch at the end which I think is necessary, especially for a beginner who may not know about cooling down and stretching. But that's the only demerit I can give this workout. I'm looking forward to trying Frontside soon.
I bought this set because I really like Jillian and truly miss her on TBL. For those of you who didn't care for her tough training method, this set has a much softer Jillian present.
