This is a good workout, better than the one in the original "Body Sculpting Bible." It's intense, but luckily they avoid burnout by insisting on only three workouts a week.
They also emphasize the importance of warming up, as well as stretching before and after lifting weights.
However, there are a few factual errors and some redundancies. For example, I noticed they give bad advice on walking technique (they say to walk on the ball of your foot, toe - heel rather than heel - toe as it should be. I think they got running and walking confused).
Also, the 12 week workout is broken up into three four week programs. These are excellent programs, but they reproduce each workout on four pages. There's a separate and unnecessary page for each week of the workout. For example, the pages for weeks 2, 3 and 4 are (except for the week number) are exactly the same as the page for week one - and so on. All that was needed was one page that said "workout for weeks 1 - 4" or "workout for weeks 9 - 12"). This adds several unnecessary pages, but perhaps they needed a minimum page count.
They also drop hints about aerobic exercise here and there, but give woefully eclectic and incomplete advice on it.
I would recommend this book, as the workout was challenging enough even for someone like me who has lifted weights for years.
