A lot of workout routines are designed for maximum power and weight in the hope stimulating maximum muscle gain.{these workouts aren't for everybody!}
The problem is that they tax heavily the joints & tendons { particularly chest } so may not be performed regularly enough to achieve muscle growth ,
I.E If you dont have super heavy duty joints and tendons,they may/ will tire and strain before muscle can be regularly,adequately and consistently stimulated to achieve growth.
This is why I think it is a good idea to train these weaker areas more moderately and regularly
working the muscle with key exercises that target the muscle without straining joints and tendons.
The best exercises that I know of for specifically targeting the chest with minimal joint tendon stress are the slightly declined dumbbell movements.
I prefer a rep ranges between 30-16.{ lower rep/higher weight on appointed days}
What I do when targeting a muscle group is to stimulate it with a regular " pump/wake up" sets on "other" workout days.
Then on the appointed day/s for training that specific muscle group it is already Primed.
This is a great way of shaping and filling the muscle out and achieving quality muscle gains.
I think it is a truer form of bodybuilding,rather than the power lifting desperate ego type that we've all been guilty of.{myself in particular
