Anterior deltoid
Front delt · Shoulders
- Origin
- Lateral third of the clavicle
- Insertion
- Deltoid tuberosity of the humerus
- Action
- Flexes and medially rotates the arm at the shoulder
The front head of the deltoid lifts the arm forward. It works hard in every pressing movement, which is why lifters who bench and press overhead often need little direct front-delt work.
