While most of the trainers train all of their body muscles, it is possible to skip a few muscles and focus on the rest. The best example is all of the guys who don't care about the legs and can end up looking like chickens. What I'm looking for is more example for this unevenness.
How would a guy that only does chest-press but never chest-fly look like?
How would a guy that only does back exercises but not shoulders look like?
How would a guy that only does triceps exercises but not biceps look like?
Is there anywhere photos of such cases?
Although I'm curious about the subject in general, specifically I'm a bit more interested in the first example (chest-press without chest-flies) because that's my current workout due to itching shoulders.
