Supraspinatus muscle (first 20 degrees), Medial Deltoid (beyond 20 degrees). This is the reason why many weight lifters, performing Lateral Shoulder Raises 'bounce' or 'flick' the weight at the beginning of the movement when fatigued or the load is too heavy - to circumvent the weak suprasinatus

What muscles and bones are used to pick up an object?
The biceps brachii, deltoid (anterior portion), brachioradialis and brachialis are used when you lift a glass to drink from it. The shoulder girdle muscles are also involved, including the trapezeus muscle across the top of your back. Chest muscles (muscles of respiration) are secondarily involved.

Each clavicle articulates with the manubrium of the sternum; these are the only direct connections between the pectoral girdle and the axial skeleton. Skeletal muscles support and position each scapula, which has no bony or ligamentous connections to the thoracic cage.
