It is a book about training your pull shot, making it faster, more accurate, with greater focus. It has sections on playing offense using a pull shot, and on playing defense against a pull shot. It does not show you how to make a pull shot. Basically, you use the pull shot that you already have and make it faster, more accurate, etc. The book teaches conditioning and eye-hand coordination. Making an ultimate pull shot does not require that you strain your muscles or endanger your health. The better you condition yourself, the better you train your eye-hand coordination, the better your pull shot will be. Anyway, check it out, it's free. Stay safe. There should be a vaccine soon.
