That is why you keep mixing up your routine and workouts hitting muscles from different angles to keep your body guessing and forcing it to respond with growth. In regards to overtraining your forearms, since they are used in everyday activity, like typing even, or carrying grocerys or a bag, they adapt to being used, even though they aren't being directly stimulated with a movement like a wrist curl. So hitting them once a week alone won't necasarily be overtraining. Same thing with abs. They are stimulated with almost everything you do. But training them three times a week isn't necasarily overtraining them.
It also depends on what type of training you do regulary. I am an avid powerlifter. While I do exercises like power cleans, deadlifts, clean high pull, snatches, etc... my forearms are being stimulated more then if I wasn't powerlifting. There for, I don't really find it necasary to work forearms everyweek. Hopefully that wasn't too confusing and made some sense. Good luck bro.
