Query: save your $$

I thought this book is drivel. Itis nothing more than a series of badly written, rambling articles written in the breathlessly enthusiastic style that is typical of body building mags. It does contain some suggestions for interesting excercises and tips on how to make equipment, but you can find all that for free by doing a Google on "grip strenth training"There is not one diagram or word of explanation for the muscles in the hand and forearm and what movements they control. Not one! Other than suggesting ideas for the exercises themselves, there is no real discussion about an actual exercise program. Should one do 5 reps or 50 reps? Is it best to exercise every day? Twice a week? The book is no help.If you cant get enough of the magazine article and you want to read a bunch of badly written accounts of who squoze what and when then this book is for you - otherwise save your $$
