Overactive and underactive muscles are a result of muscle imbalances, which can be caused by poor posture, stress, repetitive movements, or injury. Overactive muscles are shortened, tight, and strong (hypertonic), while underactive muscles are lengthened, inhibited, and weak (hypotonic). To identify overactive muscles, a static posture assessment can be performed, focusing on five kinetic chain checkpoints: feet/ankles, knees, hips, shoulders, and head. Once overactive and underactive muscles are identified, a corrective exercise program can be developed to restore proper muscle balance and function. This typically involves lengthening overactive muscles through stretching and foam rolling, and strengthening underactive muscles through targeted exercises.

Overactive muscles are shortened, tight, and strong
The first step in identifying overactive muscles is to look for muscle imbalances and improper movement patterns. This can be done by performing a static posture assessment, which involves examining the five kinetic chain checkpoints: feet/ankles, knees, hips, shoulders, and head.
Once overactive muscles have been identified, they can be inhibited and lengthened through self-myofascial release (SMR) techniques such as foam rolling or using a lacrosse ball, softball, or back-buddy. Stretching techniques can also be applied to help lengthen the shortened muscle.
It is important to note that overactive muscles are often a result of repetitive movements, poor posture, injury, or stress. For example, the hamstrings, hip flexors, and muscles in the neck and shoulders are commonly associated with adaptive shortening due to prolonged sitting or repetitive postural positions.
By addressing overactive muscles through corrective exercises and improving daily habits, individuals can restore proper posture, muscle balance, and functional movement.

Underactive muscles are lengthened, inhibited, and weak
Overactive and underactive muscles are the result of muscle imbalances. These imbalances can be caused by repetitive movements, poor posture, injury, or stress. When a muscle is underactive, it is lengthened, inhibited, and weak (hypotonic). This means that the muscle is relatively less active during a joint action.
A person with overactive and underactive muscles will usually demonstrate predictable patterns of dysfunction. To identify these imbalances, a licensed professional can perform specific assessments, such as passive range of motion and manual muscle testing.
The first step in addressing underactive muscles is to inhibit and lengthen the overactive muscles. This can be done through self-myofascial release (SMR) techniques such as foam rolling or using other tools like a lacrosse ball or softball. The next step is to stretch the overactive muscles to help lengthen them.
Once the overactive muscles have been addressed, the focus shifts to activating and strengthening the underactive muscles. This can be achieved through isolated exercises that target specific weakened and elongated muscles. It is important to strengthen underactive muscles to improve overall functional movement and efficiency.
By following these steps and incorporating corrective exercises, individuals can work towards restoring proper length-tension relationships and improving muscle balance.

Causes of muscle imbalance include poor posture, stress, repetitive movement, or injury
Muscle imbalances can be caused by a variety of factors, including poor posture, stress, repetitive movements, and injuries. These factors can lead to overactive and underactive muscles, which can cause further issues and impact your overall movement and function.
Poor posture is a common cause of muscle imbalance. Slouching or maintaining an abnormal posture for extended periods can place unnecessary stress on certain muscles and lead to imbalances. For example, sitting with a hunched back can cause the muscles in the front of your body to become overactive and shortened, while the muscles in the back can become underactive and lengthened.
Stress can also contribute to muscle imbalances. This includes both physical and mental stress. Physical stress can be caused by overexertion, repetitive movements, or incorrect techniques during physical activities. Mental stress, such as long work hours or emotional strain, can also impact muscle function and contribute to imbalances.
Repetitive movements are a significant cause of muscle imbalance. This can include any activity that involves frequent repetition, such as sports, work tasks, or even practicing an instrument. These repetitive motions can lead to a gradual buildup of damage to muscles, tendons, and nerves, resulting in conditions like repetitive strain injury (RSI).
Injuries can also lead to muscle imbalances. Previous injuries, such as a rotator cuff tear or an injury to your wrist, back, or shoulder, can predispose individuals to muscle imbalances. Additionally, new injuries can occur as a result of muscle imbalances, creating a cycle of dysfunction.
It is important to address muscle imbalances to prevent further issues and ensure proper movement and function. This can be done through targeted exercises, corrective exercise programs, and working with professionals like physical therapists to diagnose and address imbalances.

Overhead squat assessments can help identify overactive and underactive muscles
Overhead squat assessments can be an effective way to identify overactive and underactive muscles. Overactive and underactive muscles are a result of muscle imbalances, which can be caused by poor posture, stress, repetitive movement, or injury. Overactive muscles are shortened, tight, and strong (hypertonic), while underactive muscles are lengthened, inhibited, and weak (hypotonic).
To perform an overhead squat assessment, stand with your feet shoulder-width apart and your toes pointed straight ahead. It is best to do this barefoot. Raise your arms overhead with elbows extended and palms facing forward. Then, get a friend to take a picture of you from the front and side as you squat down.
From the front, you should observe the lower body alignment. The feet should remain straight, and the knees should track in line with the foot. Observe if the knees move inward and if the feet flatten or turn out to the sides. From the side, you can identify if there is an excessive forward lean or low back arch. If the tibia shifts forward, the torso will also shift forward.
Once you have identified any imbalances, you can begin to correct them. Overactive muscles should be stretched and released, and underactive muscles should be strengthened. For example, if you have an overactive, tight TFL, you will need to stretch and release it to be able to effectively activate your hamstring and glutes.

Treatment plans can include corrective exercises, foam rolling, and strengthening exercises
Treatment plans for overactive and underactive muscles can include corrective exercises, foam rolling, and strengthening exercises. Corrective exercises are defined as "the systematic process of identifying a neuromusculoskeletal dysfunction, developing a plan of action, and implementing an integrated corrective strategy".
The NASM Corrective Exercise Continuum consists of four steps: inhibiting the overactive muscles, lengthening the shortened muscles, activating the underactive muscles, and finally, integrating back into a total body movement pattern. Overactive muscles are shortened, tight, and strong (hypertonic), while underactive muscles are lengthened, inhibited, and weak (hypotonic).
Foam rolling is a technique used to release overactive muscles and improve flexibility, muscle recovery, movement efficiency, and pain reduction. It is important to perform foam rolling before static or dynamic stretching activities to improve the tissue's ability to lengthen. Various tools can be used for foam rolling, such as medicine balls, handheld rollers, or other assistive devices, and it is crucial to maintain core stability during the exercises.
After foam rolling and releasing the overactive muscles, the next step is to lengthen the muscles through static stretching or other techniques such as neuromuscular stretching or proprioceptive neuromuscular facilitation (PNF). This process of retraining the muscles is similar to tuning a piano, as the muscles need to be conditioned to stay at the optimal length.
The final step in the corrective exercise continuum is activating the underactive muscles with strengthening exercises. This involves targeting specific underactive muscles with exercises such as floor bridges and planks to activate the gluteus maximus and core stabilizers. Positional isometrics and isolated strengthening techniques can be used to increase neuromuscular coordination.
