I want to bring up my arms as they are very underdeveloped compared to the rest of my body. I have been training my arms 2 times a week. Usually a larger body part then followed with biceps training or triceps training separately. I also have a dedicated arm day where I train my biceps and triceps together once every two weeks. What do you think? Too much volume or too little?
For the arm day, I usually do the heavier compound movement first (close-grip bench, barbell curl) and followed by isolation movements while incorporating drop sets, super sets, etc. When I train my biceps or triceps after training larger body part, I just do 2-3 isolation movements light-moderate weight.
I have also been training my legs once in two weeks for almost a couple months, as I am happy with what they are now (my quads grow easily and my calves are still 1 inch bigger than my arms flexed) so that I have energy to improve weak body parts especially my arms, they don’t seem to be decreasing in size as my measuring tape suggests.
