If you’ve ever experienced persistent tightness in your upper arm, you may be dealing with trigger points in a muscle called the brachialis. While many people are familiar with the biceps and triceps, the brachialis is often overlooked despite playing a major role in elbow movement and arm function.
A simple brachialis release technique using a lacrosse ball can help reduce tension, improve mobility, and address areas of tenderness that may be contributing to discomfort. In this guide, we’ll explain what the brachialis muscle does, why trigger points develop, and how to perform an effective arm muscle trigger point release at home.
What Is the Brachialis Muscle?
The brachialis is a strong muscle located in the front of the upper arm, underneath the biceps. The muscle originates on the front portion of the upper arm bone (humerus) and attaches near the forearm, crossing the elbow joint.
Its primary function is to flex the elbow, making it one of the most important muscles involved in lifting, pulling, and carrying activities.
Every time you:
- Pick up a grocery bag
- Carry a child
- Perform a pull-up
- Lift weights
- Bend your arm
The brachialis contributes to elbow flexion and helps stabilize movement.
Why Trigger Points Develop in the Brachialis
Like many muscles, the brachialis can develop areas of tension known as trigger points. These small knots form when muscle fibers become irritated or overworked.
Common causes include:
- Repetitive lifting
- Strength training
- Manual labor
- Excessive gripping activities
- Poor movement mechanics
- Prolonged muscle tension
When trigger points develop, they can create localized soreness as well as referred pain that travels into nearby areas.
Some people may even mistake brachialis-related discomfort for elbow pain or other arm conditions because the symptoms often overlap.
If you’re experiencing persistent symptoms, it may be helpful to learn more about elbow pain and the different factors that can contribute to discomfort around the joint.
How Trigger Point Pain Affects Movement
One of the most common effects of trigger points is reduced mobility.
When tension builds within the muscle, it can:
- Limit range of motion
- Create discomfort during lifting
- Reduce strength
- Cause stiffness when bending the arm
- Increase stress on surrounding muscles
Over time, compensation patterns may develop as the body attempts to avoid the painful area.
In some cases, muscle tension in the arm can even contribute to discomfort that extends toward the shoulder. If symptoms are traveling upward, you may also want to explore common causes of shoulder pain.
How to Perform a Brachialis Release
A lacrosse ball is one of the easiest tools for releasing tension within the brachialis muscle.
Step 1: Position Your Arm
Bring your arm close to your side with your elbow slightly bent.
This helps expose the brachialis and allows you to apply pressure more effectively.
Step 2: Place the Lacrosse Ball
Position the lacrosse ball against the front-middle portion of the upper arm.
You can use a wall to help control the amount of pressure.
Apply firm but tolerable pressure.
Step 3: Search for Tender Areas
Slowly roll the ball around the muscle until you find a tender spot.
Often, the most sensitive areas are where the largest trigger points are located.
Don’t be surprised if one section feels significantly more tender than another.
Step 4: Hold Pressure
Once you locate a tender area:
- Hold steady pressure
- Breathe normally
- Maintain the position for approximately 45 seconds
This sustained pressure helps encourage the muscle fibers to relax.
Step 5: Move to the Next Area
After completing one location:
- Roll the ball slightly
- Find another tender spot
- Repeat the process
Continue working your way along the brachialis muscle until you’ve addressed the entire area.
Common Mistakes to Avoid
When performing an arm muscle trigger point release, avoid these common errors:
Applying Too Much Pressure
More pressure is not always better.
The goal is to create a therapeutic response, not excessive discomfort.
Moving Too Quickly
Many people roll the ball constantly without allowing the tissue time to release.
Pause on tender spots and let the pressure work.
Ignoring Multiple Trigger Points
The first tender spot you find is often not the only one.
Take time to evaluate the entire muscle.
Holding Your Breath
Slow breathing helps reduce muscle guarding and allows the tissue to relax more effectively.
Benefits of Brachialis Release
Regular soft tissue work can help:
- Improve range of motion
- Reduce trigger point pain
- Improve comfort during lifting activities
- Support healthier elbow mechanics
- Decrease muscle tension
- Improve recovery after exercise
Many people notice improved movement immediately after performing the release.
When Self-Treatment Isn’t Enough
While self-release techniques can be highly effective, chronic muscle tension sometimes involves more than the muscle itself.
Persistent symptoms may be related to:
- Movement restrictions
- Overuse injuries
- Postural imbalances
- Joint dysfunction
- Repetitive stress patterns
In these situations, professional evaluation may help identify the root cause.
Services such as trigger point therapy are specifically designed to address stubborn muscle tension and soft tissue dysfunction.

Improve Arm Mobility and Reduce Muscle Tension
A simple brachialis release can be an effective way to reduce muscle tension, improve elbow function, and address uncomfortable trigger points.
When performed consistently, this technique may help improve arm mobility, decrease discomfort, and support healthier movement patterns.
If symptoms continue despite self-care, professional treatment may help uncover underlying factors contributing to the problem and provide a more comprehensive solution.
Frequently Asked Questions
What is the brachialis muscle?
The brachialis is a muscle located beneath the biceps that plays a major role in elbow flexion and arm strength.
What causes trigger points in the brachialis?
Trigger points can develop from repetitive use, lifting, overtraining, poor movement patterns, and prolonged muscle tension.
How long should I hold pressure on a trigger point?
Hold steady pressure for about 45 seconds before moving to another tender area.
Can brachialis trigger points cause referred pain?
Yes. Trigger points can create referred pain that travels into nearby areas of the arm or around the elbow.
When should I seek professional treatment?
If symptoms persist, limit movement, or repeatedly return despite self-treatment, professional evaluation may help identify the underlying cause.
