I coach for all kinds. So for muscle yes. I'll give you an example (you can test this very easily):
Bench press. Try wide, medium and narrow grips. Same weight, same reps, different feel. Flat bench, decline and incline (same variations). Now you KNOW, first hand, that they can and do feel differently. So Arthur Jones (of Nautilus fame) said a slight incline was best (10 degrees - like a plate under the end of a flat bench).
Now the trick: take whatever grip you like on a barbell for the bench - as you lower the bar try gently pulling your hands apart. Not enough that they move but enough that you feel the rear delt being hit. Do that for a few reps. It shows how bad form takes a LOT of the stress off the pecs.
Now try it the other way. Lower and raise the bar at a steady speed (not silly slow nor silly fast) and PULL the hands together. The WHOLE FKIN REP you should feel the pecs activated. It's the same as if you 'squeezed' throughout.
I coached a local through a chest workout on Sunday and Monday I got 'my chest is in bits'. Took 1 hour. We used flat bench (as above), resistance bands, dumbbell flyes and press-ups
