The experience of sharp or aching pain in the upper arm during a push-up is a frequent complaint among people engaging in bodyweight exercise. This discomfort often indicates an underlying issue with the muscles, tendons, or joints, typically resulting from overuse or improper mechanics. Understanding the specific source of the pain is the first step toward correcting the problem and returning to a pain-free training routine. The upper arm bears significant load during the push-up, making it a common site for strain when form falters or volume increases too quickly.
Common Causes of Upper Arm Pain During Push-Ups
Upper arm pain during pushing movements often stems from issues with the tendons and muscles responsible for elbow extension and shoulder stability. A frequent culprit is triceps tendinopathy, which is irritation of the tendon connecting the triceps muscle to the elbow joint. This condition results from repetitive microtrauma, where the tendon is overloaded beyond its capacity, common with high-volume pushing exercises. Symptoms typically manifest as a dull, aching pain at the back of the elbow, exacerbated when straightening the arm against resistance.
A strain of the triceps muscle fibers, which runs along the back of the upper arm, is another potential cause of acute pain. This injury occurs when the muscle is subjected to excessive tension or a sudden traumatic force, leading to microscopic tearing. Pain from a muscle strain is usually felt higher up in the arm than tendinopathy and may be accompanied by weakness during the pushing motion.
Pain localized to the front of the upper arm, near the shoulder, can point to a biceps tendon issue, such as biceps tendinopathy. The biceps acts primarily as a stabilizer during the push-up, but its tendon runs through the shoulder joint and can become irritated by repetitive pressing exercises. Improper form, particularly allowing the arms to flare out excessively, can increase the strain on the biceps tendon as it works to stabilize the joint.
Referred pain from the shoulder joint itself, specifically from shoulder impingement, can also feel like upper arm pain. Impingement occurs when the rotator cuff tendons get pinched between the bones of the shoulder joint, often aggravated by the compressive forces of a push-up. This pain is commonly felt on the top and outer side of the shoulder, spreading down the arm, and is often worsened when the arm is lifted overhead. Poor technique, such as letting the shoulder blades elevate toward the ears, can narrow the space in the shoulder joint and trigger impingement.
Immediate Steps for Relief and Activity Adjustment
When experiencing a flare-up of upper arm pain during push-ups, immediately stop the painful activity. Continuing to push through discomfort will further irritate the muscle or tendon and delay healing. Applying the principles of Rest, Ice, Compression, and Elevation (R.I.C.E.) can help manage acute symptoms and reduce initial pain and swelling.
Resting the affected area means avoiding activities that reproduce the pain for at least 24 to 48 hours. Cold therapy, such as applying an ice pack for 15 to 20 minutes several times a day, can help decrease localized swelling and dull the sensation of pain. For tendon pain, load management is necessary, meaning the load must be reduced to a level the injured tendon can tolerate without a significant increase in symptoms.
To maintain upper body strength while healing, the standard push-up must be modified or replaced. Incline push-ups, performed with hands elevated on a sturdy surface, dramatically reduce the body weight the upper arm structures must support. This modification allows for continued strength training while reducing forces on the shoulder and elbow tendons. Performing push-ups from the knees or limiting the range of motion to a partial descent can also decrease the overall strain.
Biomechanical Adjustments for Pain-Free Push-Ups
Correcting the biomechanics of the push-up is the primary long-term strategy for preventing the recurrence of upper arm pain. Proper hand placement is foundational: hands should be placed directly beneath the shoulders or slightly wider to minimize stress on the joint. Fingers should be spread wide and pointed straight ahead or angled slightly outward to create a stable base.
The angle of the elbows as the body descends is a key adjustment. Flaring the elbows out wide to a 90-degree angle places excessive stress on the anterior shoulder joint, contributing to impingement and biceps tendon irritation. Instead, the elbows should be tucked closer to the body, aiming for approximately 45 degrees relative to the torso. This tucked position shifts the mechanical load onto the chest and triceps muscles, which are better suited to handle the force.
Maintaining correct shoulder and torso positioning is also important for joint health. The shoulders should remain depressed, actively kept away from the ears, and the shoulder blades should be retracted slightly. This action stabilizes the shoulder joint and maintains space for the rotator cuff tendons to move freely.
The entire body must maintain a rigid, straight line from head to heels, achieved through active engagement of the core and glutes. Preventing the hips from sagging or the lower back from arching ensures the shoulder joint remains in its optimal position. Focusing on a slow and controlled descent and ascent allows for better muscular control and reinforcement of proper form, distributing the body’s weight more effectively.
Signs Indicating a Need for Professional Consultation
While many cases of upper arm pain can be managed with rest and form correction, certain signs indicate that a professional medical assessment is necessary. Sharp, shooting pain that occurs immediately upon attempting a push-up or during simple daily activities warrants consultation with a physical therapist or physician. This intense, localized pain can signal a more significant tear or acute structural damage rather than a simple strain or overuse injury.
The presence of numbness or a tingling sensation extending down the arm or into the hand suggests possible nerve involvement, requiring immediate medical evaluation. Persistent pain that does not improve after seven to ten days of rest and activity modification is concerning. If the pain consistently disrupts sleep, or if there is visible swelling, bruising, or a noticeable deformity around the joint, professional care should be sought. A medical professional can accurately diagnose the underlying issue and prescribe a targeted rehabilitation program.
