seems like it only keeps popping up new questions, hope you dont mind answering em, tell me if im getting annoying

anyways i was wondering if its ok to maybe drop the biceps and triceps training for a while and concentrate on chest and back 2 times a week and then shoulders n legs 1 time a week, how much will the biceps and triceps suffer from not beeing trained for a while, and how long could i go on with chest and back 2 times a week untill i should start training biceps and triceps again, any ideas ?
thx mate
