I have given a middle of the range mark as two of these are ok and two I binned. The two that were ok were the Cardio Hip Hop and the Belly, Butt and Thigh Blasters.
Cardio Hip Hop was the one I expected to give throw out or ignore but it is surprisingly good. Fair enough, it is cheesy (and the silly outfits don't help!) but if it were simply called 'Dance Cardio' or similar that would give a better expectation, as it is mostly general dancy moves rather than what you would expect based on Hip Hop videos. I mentioned it is cheesy but no more so than Zumba or Salsa really.
The Belly, Butt and Thigh... with a sculpting loop is very good. It is varied with all standing work that doesn't have too much stop-and start in between moves. You need a good sense of balance - or a desire to work toward this - as it is hard not to wobble on a lot of the leg extensions.
The other two were Suzanne Bowen who I remember liking year's ago. I can see why, as her manner is excellent. However these old school exercises (it felt like there was a variation of the plank in every single section!) left me bored rigid. It is nearly all floor work for both DVDs - based on planks, crunches and leg raises. It reminded me why I never buy Yoga, Pilates or Mat workouts.
