For anyone who has purchased this video, does it meet ACOG's current recommendations? I noticed that the website states "the ACOG offers these general guidelines for exercise during pregnancy: After 20 weeks of pregnancy, avoid doing any exercises on your back." This is not the current recommendation released by ACOG in 2002, so I just wondered if the site had not been updated or if she is using some (maybe all) the old recommendations i.e., heart rate not exceeding 140. Of course, I know some OB/Gyns who still follow the old recommendations or mix the new and old. Even some of the Prenatal Fitness websites seem to use a combo of the old and new recommendations. Just curious if anyone knows before I recommend it to a client/patient (the docs I collaborate with follow ACOG guidelines, so when I represent them I try to do the same). Thanks in advance!
