Effective Training to Broaden Your Shoulders

Broad shoulders are often associated with physical strength and vitality. Traditionally, this trait has been more associated with men, but it's becoming increasingly sought after by women as well. This post aims to provide a comprehensive understanding of the shoulder anatomy, how to broaden your shoulders, and the best exercises to achieve this goal.

Understanding Shoulder Anatomy

The shoulder region, located between the neck and the upper part of the torso, represents the widest part of the human figure. The breadth of the shoulders is largely determined by bone structure, including the length of the clavicles and the configuration of the glenohumeral joint.

However, the skeletal muscles, such as the deltoids, also contribute to the shoulder's width. These muscles can be developed through targeted exercises, offering a variable margin of improvement. The deltoids are the most "external" muscles of the shoulders, and their development is essential for broadening the shoulders.

The deltoids are divided into three bundles:

  1. Front Deltoid: Responsible for flexion of the humerus, anteversion of the shoulder, and internal rotation.
  2. Lateral Deltoid: Responsible for true abduction of the humerus and anteroposition of the shoulder.
  3. Rear Deltoid: Involved in the extension of the humerus, the retroposition of the shoulder, and external rotation.

The lateral bundle is the most important in terms of broadening the shoulders.

Effective Exercises for Broadening Shoulders

The primary movement to perform for wider shoulders is the true abduction of the humerus, commonly known as the lateral raise. However, shoulder training is more complex due to the involvement of other large muscle groups and the trapezius muscles, which form part of the shoulder and back regions.

The best exercises for broadening your shoulders include lateral raises, chest pulls with an EZ barbell, and complex exercises like the Arnold press and military press. It's important to note that using the correct technique and avoiding excessive volume are crucial for effective shoulder training.

Principles of Muscle Growth

The increase in muscle mass is due to two factors:

  1. Myofibrillar hypertrophy: This involves an increase in the actual contractile tissue, which is achieved by becoming stronger. It's obtained by training with high percentages of overload and low repetitions. Recoveries are generally complete.
  2. Cytoplasmic hypertrophy: This involves an increase in other cytoplasmic components in the fibrocells, such as water, organelles, glycogen, enzymes, etc. It's achieved by stimulating the increase in energy reserves and the production/disposal of lactic acid, through medium-high load percentages and greater repetitions.

A positive caloric balance, or consuming more calories than you burn, is also necessary for muscle growth. Supplements like creatine monohydrate and beta alanine can also assist in this process.

Training Frequency and Volume

The frequency and volume of shoulder training depend on several factors, including how often the deltoids are activated in other exercises. In general, training the shoulders once a week may be sufficient. However, since the goal is to broaden the shoulders, the development of the lateral deltoid should be the primary focus.

It's important to note that your shoulders also get a workout when you try to stimulate other areas. For instance, the front deltoid is involved in push work for the pectoralis major, and the rear deltoid participates in back exercises.

The Importance of Technique

While shoulder training doesn't generally cause significant fatigue for the central nervous system and overall metabolism, it requires meticulous technical care to prevent injuries. The goal is to target the central beam as much as possible, which requires constant quality work. This includes always performing clean reps, maintaining focus, and knowing when to stop to avoid overtraining, thereby ensuring that your pursuit of broader shoulders is both effective and safe.


In conclusion, broadening your shoulders involves understanding the anatomy, performing the right exercises, and adhering to the principles of muscle growth. It's a process that requires patience, consistency, and technical precision. However, with the right approach, it's possible to achieve appreciable results within a few months.
