I'd actually give this 3.5 stars, but I'll be generous & round up. The book is interesting to get a feel of how Pilates initially introduced his methodology. However, the book is very outdated - in language, philosophy & even medical advice. My other complaint was a lot of the writing was focused on exposing the "quacks" in the physical fitness & medical fields. A lot of preaching. Despite all this, I do think there is solid information buried in there. It's also interesting to see how Pilates, in the 1930s & 1940s, saw the abundance of misinformation regarding health, & that pushing the body to extremes was not the answer. Yet, here we are 80-100 years later and we've kept pushing.
