This brilliant DVD is made up of 3 segments, each just 15 minutes long, so you can do as much as you are able or have time to do. Erin is a warm and supportive instructor, who takes you through a series of mainly core exercises specifically aimed at the muscle groups that suffer when you're pregnant and breastfeeding. I wish I had this years ago... my youngest 'baby' is now 11 years old, but after some (not uncommon) spinal nerve damage, I found my abs very unresponsive for a very long time. This DVD isn't called Rescue for nothing, it really delivers! You have nothing to lose by buying Postnatal Rescue, except perhaps a spare tyre!
