Guys, go on with personal messages about close mindness and children because that does NOT belong on forum!
Jonas,
SHF site and forum are friendly oriented to anyone, to provide informations and advices to anyone who need it. There are some members who are always trying to give away maximum effort to deal with problems and Daniel is one of them. We are not always with same opinions, but we always keep proffesional level about things we discuss (with researches, science, experiences,...) and we keep personal respect even we argue about something we don't agree! Because only that way we can offer quality informations to others.
I think you studied at least one listed subject quite bad. If you put in google you will get workouts for upper, middle, lower, inner...chest. That's because exist science and broscience and because some things are generalized and after some time accepted as "truth". The most obvious thing or term is weight. When you step on scale, you measure your MASS, but we always talk about WEIGHT. Since you are european where we have metric unit system, mass is measured in kilograms and weight is measured in Newtons because weight is a force. I won't go further with generalization phenomenon.
If you can't keep normal level of communication, don't participate or leave forum or you will be leaved. You showed at least disrespect to someone who is proffesional in his field beside that you didn't provide any useful informations to those who are begginers and without knowledge and want to get quality informations.
BR, Gregor
