My forearms seem to be in line with the development of the rest of my physique although I do not do any special forearm work.
Do you believe the forearms should be trained specifically each workout?
I wish people would think more for themselves. You have answered your own question.
If your forearms are keeping pace with the rest of your development, then they are getting enough overspill from your other exercises.
After all nearly every exercise brings the forearms strongly into play. It is only at times when your lower arms are failing to develop that you should include individual exercises such as wrist curls and reverse curls.
Few bodybuilders spend much time working out their forearms with these exercises, but there are occasions when an arm starts to take on a look of imbalance and specialized forearm work is needed.
