There is technique for building a specific muscle. The way you move will affect how some muscle groups are loaded. For example, using a very small amount of internal rotation of the femur during squats will put more load on the quads. Whereas going into external rotation will deload the quads and put more load on the adductors. Subtle technical details like that are important to pay attention to for building muscle. Just as important as technique to move weight.
