Ross Enamait always puts out excellent material. I've not bought this book, but own several of his others. A quality guy all round.
For people with a serious interest in grip strength, there is also 'The grip master's manual' by John Brookfield (free pdfs are available online without 'needing' to torrent). It's an awesome manual that can give you some serious hand and wrist strength.
