This DVD really is first class. All the moves are carefully explained, with likely common errors pointed out and what to do if you find the moves "too strong" - her term, I would just say excruciating! Having said that, the things I found 'too strong' just a few weeks ago are now considerably easier - I am definitely firmer, fitter and more flexible, just as it says.
I positively enjoy following this DVD - I really like her calm, reassuring, but not patronising manner, and I feel very confident she knows what she's talking about, unlike some other 'celeb' videos I have seen. The instructions are very clear, eg on how you should be breathing, and things to beware of - "watch you're not dropping your hip" - this again helps me feel confident that she's done this many times before. Following the same routines you can really measure your progress as the weeks go by, and there's a fair amount of variety in the DVD, so it's not boring. Sadly I don't (yet) look like her guinea pigs, nor have I taken to exercising in full make-up (yet), but give it time!
