Haven't tried piyo but I have done 21 day fix with autumn! I think piyo is beachbody too, right? My mom had 21 day fix..I just did the workout part so can't comment on the container part but my mom still follows it and loves it. Autumn is awesome. I know she has pregnancy workouts that may be worth taking a look at too- https://www.beachbody.com/product/bod/exclusive/pregnancy-workouts-exercises.do Would recommend anything she does especially since seeing that stomach of hers motivates me to do anything! haha
