Muscle memory is a real phenomenon, but it might not work as you think. Muscle memory is often associated with the ability of muscles to remember specific movements, such as riding a bike or playing a musical instrument. However, the actual process of muscle memory occurs in the brain and the central nervous system, where motor learning and the formation of neural pathways take place. This type of muscle memory is referred to as neurological or procedural memory. There is also physiological muscle memory, which is related to the regrowth of muscle tissue and the retention of muscle mass after periods of inactivity. While muscle memory is beneficial for learning and improving physical skills, there is a caveat. Without proper guidance, incorrect movement patterns may become ingrained, potentially leading to injuries or inefficient performance. Understanding the two types of muscle memory can help individuals establish or reboot a fitness routine effectively and avoid potential drawbacks.

What You'll Learn
Muscle memory is real, but it's not what you think
Muscle memory is indeed real, but it's not as simple as your muscles remembering a movement. The term is something of a misnomer, as muscles don't technically remember anything. Instead, muscle memory is a type of motor learning that occurs in the central nervous system (CNS) – the brain and spinal cord.
When you learn a new physical skill, such as riding a bike, your brain and spinal cord work together to create and strengthen neural pathways. These pathways transmit signals to the relevant body parts, allowing them to perform the required movements. With practice, these movements become smoother and can eventually be performed without conscious effort. This is why, even after a long period of not riding a bike, you can usually hop on and pedal with ease.
There are two types of muscle memory: neurological and physiological. The former is tied to the recall of learned activity and the creation of neural pathways, as described above. The latter is related to the regrowth of muscle tissue. When muscles are stressed to the point of hypertrophy, they grow new cells to get stronger. These cells contain myonuclei, the key indicators of muscular growth. It was previously thought that these cells would die off if the muscles were no longer used, but recent studies suggest that they are retained, even as the muscle shrinks. This means that if you build muscle during your younger years, you may be able to regain that muscle more quickly later in life, as the myonuclei are reactivated with retraining.
However, it's important to note that the exact mechanism of muscle memory is still not fully understood, and more research is needed. The location of muscle memory storage is also not known, although studies suggest that inter-regional connections between different areas of the brain are important for muscle memory consolidation.

Muscle memory is long-lasting, maybe even permanent
Muscle memory is indeed a real phenomenon, but it is important to note that muscles themselves do not "remember" anything. The term "muscle memory" is used to describe two separate concepts: neurological muscle memory and physiological muscle memory. Neurological muscle memory is tied to the recall of learned activity, or the ability to remember movements. Physiological muscle memory, on the other hand, is related to the regrowth of muscle tissue and the ability to quickly regain muscle mass in previously trained muscles after a period of inactivity.
Research has shown that muscle memory can be long-lasting and perhaps even permanent. For example, a recent study involving men in their 50s to 70s found that after a period of resistance training followed by a detraining period, the participants were able to regain their previous strength levels in less than eight weeks of retraining. This suggests that muscle memory can persist over time, even as muscles shrink.
The longevity of muscle memory can be attributed to the retention of muscle cells and myonuclei, which are the nuclei inside muscle fibres. When muscles are stressed to the point of hypertrophy, they grow new cells to become stronger. It was previously believed that these cells would die off if the muscles were not used, but recent studies have challenged this notion. In one study of mice, it was found that extra nuclei gained during periods of training were retained in distinct muscle fibres even during subsequent periods of inactivity. These dormant nuclei can then be reactivated with retraining, allowing for faster muscle regrowth.
While the exact mechanisms of muscle memory are still being debated, it is clear that muscle memory can have long-lasting effects. The more you exercise and practice a skill, the more you reinforce these muscle memories and the easier it becomes to recall them in the future. This is why activities such as riding a bike or driving a car can be performed effortlessly even after a long period of inactivity.

Muscle memory is of two types: neurological and physiological
Muscle memory is a form of procedural memory that involves consolidating a specific motor task into memory through repetition. It is important to note that muscle memory is not the ability of the muscles to remember movements. The term is a misnomer because muscles do not remember anything. In the brain, information is encoded, stored, and retrieved. What we perceive as muscles "remembering" refers to motor learning that occurs in the central nervous system (CNS), not the muscles.
Neurological muscle memory is associated with learning new skills and motor learning, such as learning to play a musical instrument or perform a physical activity. Performing an action repeatedly activates neurons in certain parts of the brain, particularly the cerebellum and basal ganglia, and creates a new neural pathway between the CNS and the muscles being moved. Once muscle memory is established, the task can be accomplished without consciously thinking about it.
Physiological muscle memory, on the other hand, is about the ability of previously trained muscles to regain muscle mass faster than the time it took to put it on in the first place. As muscles are trained, the number of muscle fibre nuclei or myonuclei can increase as muscle mass increases. Research on mice suggests that after nuclei in muscle cells proliferate in response to an overload of training, those extra nuclei are retained in distinct muscle fibres, waiting to be reactivated with retraining.

Muscle memory is influenced by genes and the environment
Muscle memory is a real phenomenon, but it might not work as most people think. It refers to the ability to quickly regain muscle mass in previously trained muscles after a period of inactivity. This is because, as muscles are trained, the number of muscle fibre nuclei or myonuclei increases as muscle mass increases.
Research has shown that muscle memory is influenced by genes and the environment. In muscle cells, genes are turned on and off in response to exercise to make certain proteins in the cell, which ultimately facilitates muscle growth and strength. The more a person exercises, the more muscle memory savings they accrue.
Genes are influenced by behaviour and the environment, and while the genes themselves do not change, the way they work does. For example, lifting weights causes small molecules called methyl groups to detach from the outside of certain genes, making them more likely to turn on and produce proteins that affect muscle growth. These changes persist, and if a person starts lifting weights again, they will add muscle mass more quickly than before. This is because the muscles have a lasting molecular memory of past exercise, which primes them to respond to exercise even after a long break.
Research has also shown that motor skills are not simply acquired through practice, and that we do not start with a blank slate with regard to motor memory. For example, facial expressions, which are thought to be learned, can be observed in blind children, indicating that motor memory is genetically pre-wired.

Muscle memory and the role of myonuclei
Muscle memory is a real phenomenon, but it works differently from how it is often presented. It does not refer to the ability of muscles to ""remember"" movements or previous levels of strength and volume. Instead, it refers to the ability to regain muscle mass in previously trained muscles. In other words, once muscle mass has been gained through strength training, if it is lost after taking time off from training, it can be regained faster than the amount of time it took to build it initially.
The role of myonuclei in muscle memory is unclear. Myonuclei are the "control centres" of muscle fibres and are added to muscle fibres when they grow. It is thought that myonuclei can only "oversee" a finite, relatively fixed volume of sarcoplasm (the "stuff" inside muscle fibres). As fibres get larger, and myonuclear domains approach their limits, muscle fibres must gain new myonuclei from surrounding cells (satellite cells) to continue growing. This is known as the "myonuclear domain theory".
While it is generally thought that myonuclei are not lost when muscle fibres shrink, the evidence is less conclusive than often assumed. Some studies show a loss of myonuclei, while others show that they are retained. The only direct evidence for myonuclei-mediated muscle memory comes from rodent studies. However, it does seem that myonuclei are lost at a slower rate than muscle fibres atrophy, and they may play a role in muscle memory, particularly for people who struggle to accrue more myonuclei, such as elderly people or those who struggle with muscle growth.
Research has shown that muscle memory is long-lasting in humans, with myonuclei stable for at least 15 years and possibly permanent. However, myonuclei are harder to recruit in the elderly, and further research is needed to determine the lifespan of myonuclei gained through training and the implications for muscle regrowth.

Frequently asked questions
Muscle memory is a phenomenon where previously trained muscles acquire strength and volume after a period of disuse much faster than untrained muscles. It is of two types: neurological and physiological. The former is related to the recall of learned activity, while the latter is associated with the regrowth of muscle tissue.
Muscle memory is not bad. It helps in performing tasks like riding a bicycle or playing a musical instrument with ease. However, it is important to be mindful of the movement patterns developed, as poor technique could lead to overuse injuries.
Muscle memory works by strengthening the synaptic pathways in the brain for specific coordinated sequences of muscle movements. Through repetition, the brain and spinal cord create strong neural pathways to transmit signals to the relevant body parts.
The duration of muscle memory is uncertain. While some researchers believe it may be long-lasting or even permanent, others suggest that the extra nuclei gained through training could last for up to 15 years.
To improve muscle memory, it is recommended to have oversight from a trainer or coach to ensure proper form and technique. Additionally, getting adequate sleep and maintaining quality habits can help maximise muscle memory and motor skill consolidation.
