Hi Cathy, Carla and everyone who post later.
The workouts are good muscle workouts but if you're looking for aerobics, you'll need to add more cardio. They aren't very cardiovascularly challenging, so I am adding Turbo Jam, TAEBO and Cathe's workouts.
All of the Slim Series workouts are high rep/light weight workouts except Cool it off but it is a stretch workout.The weight work is non stop - and you do lots of reps (so you use a lighter weight). Sometimes she uses compound moves, other times, not... but giant sets are frequently used. The high rep stuff is tough! I use more weight than Debbie, but not a lot more because there are soooo many reps!The workouts are repetitive and very similar but I sweat like crazy and I am a advanced exerciser. The music is boring.
I like all the workouts except Tone it Up. I can't mantain a good form doing a bicep curl etc. when I am doing compound moves (upper/lower body simultaneously).I prefer the Cathe's endurance weight workouts like ME, PH or CTX upper body split.
Firm it Up and Shape it Up are my favorites. Firm it Up is a lower body unweight workout with lot of reps.No weights are needed but if you want to up the intensity, you can put on ankle weights.Shape it Up is a 78 minutes workout (like Tear it Up).This video uses opposing muscles groups and contains many compound movements
