This book is meant to give you the basic knowledge needed to achieve these goals. This book is included with several of our models, so the descriptions and pictures may not exactly match the machine you have bought. The exercises described can all be performed on your machine, although in some cases, only if you have purchased optional attachments. We have included descriptions of 52 different strength training exercises along with several different variations of almost every exercise. We encourage you to always seek further knowledge. Exercise science is always moving forward and good new ideas are inevitable.
