The most frequently and rapidly used are the fingers and wrist of both hands, especially the right hand over mouse. This causes carpel tunnel syndrome or similar orthopaedic disorders. I would therefore suggest to practice suksham vyayam by Swami Dhirender Brahmachari - especially the exercises meant for shoulders, wrists and fingers, everyday. If anyone wants to know more about, I will be happy to write here. You can raise the question on this answer.
