i really hate doing press-movements. is it really necessary to do them as long as i train a lot with pulling-movements? i read somewhere that pulling-movements train the pecs and triceps as well as back, shoulders and biceps… wrong?
Look through some of the exercise charts on sites such as exrx and look at what muscles different exercises help, and you’ll likely be able to answer your own question.
You need to balance pulling exercises with pressing exercises, for example rows with bench, and pull-ups with overhead press. What you are suggesting is a really bad idea.
Read about how muscles function before you ask ignorant questions like this OP.
