Query: Disappointing

I found this book to be poorly written, often times in the style of a trashy women's magazine--vapid and full of useless filler for the sake of needing enough material to write a book.I can understand how some women would find it to be inspirational to read about ultra-marathoners and Ironman competitors running while pregnant but I found it to be a bit of a turn off. How realistic is this for the average pregnant woman who just wants to run for fitness?I did find the stretches to be useful, and wish there could have been more useful information like this in the book. It felt like it read more like a pregnancy manual at times then a fitness book.
