Unlocking shoulder health: Elevating lower trapezius performance
When it comes to shoulder health, much of the focus tends to be on the more prominent muscles, such as the deltoids or rotator cuff. However, there's an unsung hero that plays a crucial role in shoulder function and overall upper body stability: the lower trapezius.
What is the lower trapezius?
The trapezius muscle is a large, triangular muscle that spans the back of your neck and upper spine, extending out to the shoulders. It's divided into three distinct parts: the upper, middle, and lower trapezius. While the upper and middle trapezius are often the focus in many strength-training routines, the lower trapezius, which runs from the lower thoracic spine (T6-T12) to the scapula, is frequently neglected.
Why the Lower Trapezius Matters:
The lower trapezius is integral to the proper movement and stability of the scapula (shoulder blade). It helps in downward rotation, depression, and retraction of the scapula, which are essential for healthy shoulder mechanics. Without proper activation and strength in the lower trapezius, other muscles may compensate, leading to imbalances, poor posture, and ultimately, shoulder pain or injury.
Scapular control
The lower trapezius works with other muscles, like the serratus anterior, to stabilize the scapula during arm movements. This stability is crucial for effective and pain-free overhead activities, such as lifting, throwing, or even simple daily tasks like reaching for items on a high shelf.
2. Shoulder function
Proper scapular positioning, facilitated by the lower trapezius, allows for optimal function of the rotator cuff and deltoid muscles. This positioning reduces the risk of shoulder impingement—a common condition where the tendons of the rotator cuff are compressed during shoulder movements.
3. Postural control
Modern lifestyles often involve long periods of sitting, leading to rounded shoulders and forward head posture. Strengthening the lower trapezius helps counteract this by encouraging scapular retraction and depression, contributing to better posture and reduced strain on the upper back and neck.
4. Injury risk reduction
By ensuring the scapula is correctly positioned during movement, the lower trapezius reduces the load on other muscles and tendons in the shoulder complex. This balanced load distribution helps prevent overuse injuries, such as tendinitis or bursitis, which are common in athletes and individuals with repetitive overhead activities.

Our go-to lower trap exercises
Prone Y-raises
Lie face down on a bed, bench, or stability ball, with your arms extended overhead in a Y position. With your thumbs pointing up, slowly lift your arms off the ground, focusing on squeezing your shoulder blades together. Hold briefly and then lower. The lower trapezius is the major mover here.

2. Prone W’s
Again, lie face down on a bed, bench, or stability ball with your arms down to your side in a W shape. With your palms facing the floor, slowly “push” your arms overhead, focusing on keeping tension between your shoulder blades. Pause briefly at the top, then return to your starting position. This uses all the trapezius muscle fibers - upper, middle, and lower - with lower acting to stabilize the shoulder blade as it rotates upward.
3. Straight arm pull down
Sit or stand with a resistance band anchored above you. Hold the band with both hands and perform a downward pulling motion, focusing on depressing and retracting the scapula. This helps activate the lower trapezius without overly engaging the upper traps.
The lower trapezius might not be as flashy as other muscles, but its role in maintaining shoulder health and function is undeniable. By incorporating exercises that target this often-overlooked muscle, you can improve your scapular stability, enhance shoulder function, and reduce the risk of injury. Whether you’re an athlete or someone who wants to maintain good posture and avoid shoulder pain, paying attention to the lower trapezius is key to unlocking optimal shoulder health.
