I was considering purchasing the book because I get arm pump all the time, but I'm still not sure. I've read quite a few reviews on review websites, but they all have similar grammatical errors, which really got me on edge...not to mention they just seem...strange. I have found no reviews on forums or by what seemed to be an actual normal customer anywhere, and I will not buy it until I am confident that it is not a scam. So I am reverting to this: Is it legit? Have you used it, or do you know someone that has? I need more supporting evidence for it.
