Title: Could be dangerous to follow her speed
Review: I am a pretty fit person (been working out at least 5 days a week, including one day with a trainer, for years), but I think this video contains prenatal exercises that are way too fast and jerky for most pregnant women. If you go at your own pace, it's fine, but following her speed (especially during the "double-time" parts) is probably too much for most women. You can tell she's a group exercise instructor--I'm sure she's a great teacher in that context. But I don't think the dismissive "you're okay, you're fine" comments she makes during the more intense parts of the video are necessarily the message to send to a pregnant woman who may be overexerting.
