One of the best starting grip articles I ever read was from a guy called Mighty Joe Musselwhite (really cant remember his last name so I am just pulling straight form my arse!)
He is a world champ arm wrestler and does all kinds of crazy grip stuff. His recommendation for everyone starting was simple. You do 3 exercises every you workout. barbell crush, standing barbell monkey grip flexion or curl and seated barbell extension. You do 4 sets of 20 and continually increase the weight.
He put like a 1/2 an inch on his forearms in 4 weeks. I really like it a lot and try to do it once a week.
