I'm working out for 9 months by now, and was, until now, trying to lose weight. Now that I'm pushing myself to weight lifting, I've found that I really need to strengthen my wrists and forearms. When I tried to do some triceps exercises or some close-grip pull ups, I had some pain that is similar to tennis elbow.
Since I do work as a programmer at an office, is there something I can do to strenghten my wrists and forearms while at the office?
