What is the trapezius muscle?
The trapezius muscle is a large, triangular muscle located in the upper back and neck. It is the most superficial muscle in the back and is responsible for movement and stability of the shoulder girdle. It also plays a key role in maintaining proper posture. (1)
There are three functional regions of the trapezius: the upper, middle, and lower fibers. Each region of the muscle has a different role in movement and stability of the shoulder girdle.
Upper fibers of the trapezius
Elevate and upwardly rotate the scapula, which is important for activities such as shrugging the shoulders or reaching overhead.
The middle fibers of the trapezius
Retract the scapula, which is important for maintaining proper posture and providing stability during exercises like rows.
The lower fibers of the trapezius
Depress and downwardly rotate the scapula, which is important for keeping the shoulders back and down during exercises such as the plank.

Common signs of weak trapezius muscles
Here are some of the most common signs of having weak trap muscles:
- Uneven shoulders, with one sitting higher than the other
- Rounded shoulders -Limited range of motion in the shoulder and neck
- Pain or discomfort in the neck and shoulders
- Difficulty performing overhead movements, such as reaching for something on a high shelf
- Frequent tension headaches
- Tendency to hunch forward when sitting or standing
- Frequently dropping things from your hand
It is worth noting that weakness in the trapezius muscle can also be a symptom of a more serious condition, such as nerve damage, so it is a good idea to see a medical professional if you are experiencing any persistent or severe symptoms.
Trapezius Muscle Exercises
There are several exercises that can be used to strengthen the trapezius muscle. These exercises typically involve either resistance training or bodyweight exercises that target the muscle in different ways. Here are a few examples:
Shrugs:
Shrugs are one of the most effective exercises for targeting the upper fibers of the trapezius muscle. To perform shrugs, you’ll need a pair of dumbbells or a barbell. Stand with your feet shoulder-width apart and your knees slightly bent. Hold the weight with your arms at your sides and your palms facing your body. Slowly raise your shoulders as high as possible, then lower them back down.
Rows:
Rows work the middle fibers of the trapezius muscle, as well as the muscles in the back, such as rhomboids, lats, and the lower traps. There are several types of rows, but one of the most common is the bent-over row. To perform this exercise, stand with your feet hip-width apart and bend forward at the hips until your torso is almost parallel to the floor. Hold a weight in each hand with your palms facing your body. Pull the weights towards your chest, squeezing your shoulder blades together.
Pull-ups:
Pull-ups are a great exercise for the trapezius muscle as well as for other upper body muscles. It mainly works on the upper fibers. To perform pull-ups, hang from a pull-up bar with your palms facing away from your body and your hands shoulder-width apart. Pull your body up towards the bar, keeping your elbows close to your body.
Downward dog:
This yoga pose works the lower fibers of the trapezius muscle and also other muscles in the upper body. To perform it, start on all fours with your hands and feet shoulder-width apart. Slowly raise your hips up and back, forming an inverted “V” shape with your body. Keep your head and neck in a neutral position.
It’s important to note that proper form and technique is key to properly activating the targeted muscles. Consult a qualified personal trainer or a physical therapist to help you with form and to design a workout plan that is tailored to your specific needs and goals. Additionally, It’s important to remember that the trapezius muscle should be balanced with the other muscle in the upper back and shoulders.
