Position-stand and review evidence indicates that muscles are best developed by loading them through their functions and at varied joint angles, so combining compound multi-joint lifts with some single-joint work and modest exercise variation helps target a muscle completely. Exercise choice should match the muscle's line of pull and the regions a lifter wants to develop.
