I'm 17 weeks pregnant, was reasonably fit before getting pregnant, stayed active for the first two months of this pregnancy and then hit a wall of nausea that lasted six weeks, during which time I did NOTHING - barely even any walking. So once I felt better, this DVD was a godsend. Erin is totally down-to-earth, encouraging, sensible but demanding - the main thing for me, as I wanted to get fitter, so it was nice to be able to push myself, but do it safely. Having done the DVD a few times, I can recommend it to anyone - if you find it too hard at first, do fewer reps or move more slowly. It's adaptable to anyone, and a really great blend of aerobic fitness and toning. Definitely not boring or a waste of time, this DVD will see me through to the end, I hope! I also love that it's clearly not heavily scripted - so you feel like you are exercising with a real person. And she is in great, inspiring shape for a pregnant lady... Couldn't recommend it more highly!
Edited to add: I did keep doing it until a week or so before I gave birth (must admit I gave birth at 37 weeks, so I don't know if I would have kept it up after that...), and I still enjoyed it. When/if I have another baby, I'll be doing it again! It helped me stay sane, fit, flexible and in touch with the pre-pregnancy me - what more could you ask?
