Grip strength training methods often overlook the importance of the 'hand-opening muscles', the finger extensors. Dr. Terry Zachary explains why most people who train grip strength focus on finger flexor muscle, wrist flexor and wrist extensor muscle exercisises, but neglect finger extensor exercises. Dr. Zachary is the developer of the Handmaster Plus hand exerciser and shows how easy it is to add complete finger muscle exercise to grip strength training using Handmaster Plus. www.handmasterplus.com www.doczac.com info@doczac.com
