Hey all, firstly, this isn't about the upper traps, but the middle and lower fibres. Im aware of their functions (scapula retraction + depression), however, is this the only way for them to grow? I know we have shrugs for upper traps and some variations like dip shrugs that tend to target the other fibres. But for most growth, such as scapula retraction during rows, is that the way to make them grow? Isometrically? As their function is to move the scapula, it has to be moved in order for them to grow?
If you don't retract your shoulder blades your middle traps won't grow, am i correct in stating this, it would seem so from experience.
Also im guessing with optimal trap development, i'll feel less of the scapula and more muscle as the area is covered.
