Both videos are good, though I do so many other exercise vids that it's hard to say how these two have helped me specifically, but I do like them. I love Jillian Michael's workouts on both DVDs and I like the cool down/warm ups on both. I like that the level 2 powersculpt is only 10 minutes long, so you can squeeze it into your day no matter how busy you are or how little you feel like strength training that day.
Bob's cardio session is INTENSE and if you can do his cardio level and Jillian's 10 min level 2 cardio back to back, you just got 30 mins of SERIOUS cardio (if you can get in level 3, thats 40 mins of serious cardio, even better
).
I like to do levels back to back, like Levels 1 and 2 of Power Sculpt and then levels 1 and 2 of Cardio Max for 1 hr of weights/cardio. The only part of either DVD I *DONT* care for is the Level 3 Powersculpt... I don't know why, but I just dont care for it so I never do it.
Also, I started weight training by using the Power sculpt DVD and I saw a noticeable improvement to my arm tone and strength after like 2 weeks, so it DOES work.
In terms of TurboJam... I like that one less. Well, let me temper that. i like that the DVD offers you like 5 distinctive workouts, so you can really mix it up. I also really, really like the 45 minute TurboSculpt. I like it A LOT. But I don't care for the cardio workouts bc I find them hard to follow. I think the moves are too complicated, frankly, and I've never been the kind of person who can memorize a routine and perform in synch with others, so for me, it's problematic. I have to stop and just watch them for like 1 - 2 minute stretches bc I honestly can't follow what they're doing. Also, I find "the tuck" to be extremely uncomfortable and rough on my back and since I don't want to work my abs constantly (since I want to make me waist seem smaller, not bigger), it's sort of counterproductive for me. Anyway, I tend to prefer simplier, more straight forward types of movements.
I've never tried any of The Firm videos.
