I would certainly recommend this DVD to all new Mum's. The exercises are in stages allowing you to start immediately after the birth and progress to further exercises as your body recovers.
It doesn't matter whether you have exercised previously. Personally I have been practicing yoga for several years and found the exercises and education invaluable. Even though I was familiar with many of the moves, knowing when they were safe to do and the benefits of them to a postnatal body was and still is really useful.
A section on preventing injury is excellent and really makes you aware of how you are carrying your baby/child. This has to be a good thing, as how many parents are there complaining of back ache from avoidable actions such as inadvertently carrying a child on the same arm!
The relaxation and breathing techniques by Amanda Latchmore are brilliant for regaining composure and reenergizing, particularly after sleepless nights or bouts of crying (either you or the baby!).
