For both men and women, the deltoids, also referred to as delts, are a very desirable muscle to build. Well-developed shoulders can give the appearance of a smaller waist (because the shoulders look broader). Therefore, well-trained delts improve the look of the entire physique.
The deltoid has three different heads: anterior (front), lateral (middle), and posterior (rear). Each head has similar functions, but they do have some variance.
