LOL...go to the poorest parts of Venezuela and you'll see lots of guys walking around with very well built chests, biceps, triceps, forearms, backs and shoulders. These guys can't afford drugs, supplements or a gym membership. They live on rice, beans, eggs, some chicken when they can afford it, and mangos. All they have is genetics, sheer determination, a set of parallel bars for dips and a high bar for pull ups. They do dips a couple of different ways to develop their chest, tris and shoulders. They do pull ups from the high bar several different ways to develop their back, biceps and forearms. Of course, these guys have underdeveloped legs since they have no access to leg machines or squat racks, but they still have thick legs from playing futbol (soccer). So, yes, you can build a good chest with dips, without benching, but if you have access to a bench and weights, by all means use them.
