Muscle memory is a term used to describe the ability to regain muscle mass faster than the amount of time it took to build it. This is because muscle memory is not about your muscle cells remembering exercise, but rather the number of muscle fibre nuclei, or myonuclei, increasing as muscle mass increases. Research has found that muscles can store memory on a molecular level from past resistance-training sessions for up to 20 weeks. This means that after taking time off from training, you can regain muscle mass faster than the first time.
| Characteristics | Values |
|---|---|
| Muscle memory definition | Muscle memory describes the ability to regain muscle mass in previously trained muscles. |
| Muscle memory and strength | Muscle memory helps you regain strength and muscle mass faster than when you first tried to grow them. |
| Muscle memory and size | Muscle memory helps you regain muscle size faster than when you first tried to grow them. |
| Muscle memory and time off training | One or two weeks off training will not make a noticeable difference in your size. However, you may notice a slight decrease in strength. |
| Muscle memory and muscle mass | It takes approximately 4-6 weeks of not bodybuilding for your muscle mass to decrease. |
| Muscle memory and water retention | A decrease in muscle size after a short period of time is due to decreased water retention and glycogen stores in your muscles. |
| Muscle memory and DNA | Researchers have discovered that muscles' DNA can rewire in response to strength training, priming the tissue for future gains. |
| Muscle memory and epigenetic memory | Epigenetic memory takes place in the muscles themselves when they're exposed to strength training. |
| Muscle memory and longevity | A study found that muscles can store memory on a molecular level from past resistance-training sessions for up to 20 weeks. |

What You'll Learn
Muscle memory helps you regain strength and muscle mass faster
Muscle memory is what helps you regain your strength and muscle mass faster than when you first tried to grow them. It's what makes it easier for you to relearn old skills that you may have stopped, like bodybuilding, lifting weights and building strength and size, even after weeks of inactivity.
Muscle memory describes the ability to regain muscle mass in previously trained muscles. This means that once you've gained muscle mass through strength training, if you lose it after taking time off from training, you can regain the muscle mass faster than the amount of time it took to put it on in the first place.
While muscle memory as we’ve known it mainly takes place in your brain, researchers recently discovered a more literal type of muscle memory, called epigenetic memory, that takes place in the muscles themselves when they’re exposed to strength training. In this instance, your muscles’ DNA can rewire in response to what you throw at it, priming the tissue for future gains.
A new study published in the journal *Medicine & Science in Sports & Exercise* found that muscles can actually store memory on a molecular level from past resistance-training sessions for up to 20 weeks. Another study, this time on mice, found that after 12 weeks of inactivity, the mice got stronger, much more quickly than the first time.
It's important to note that one or two weeks off training will not make a noticeable difference in your size. However, you may notice a slight decrease in strength. When it comes to muscle size, it takes approximately four to six weeks of not bodybuilding for your muscle mass to decrease.

Muscle memory doesn't mean your muscle cells remember exercise
Muscle memory is what helps you regain your strength and muscle mass faster than when you first tried to grow them. It's what makes it easier for you to relearn old skills, like bodybuilding, lifting weights and building strength and size, even after weeks of inactivity.

A study found that muscles can store memory on a molecular level from past resistance-training sessions for up to 20 weeks.
However, it's important to note that muscle memory is not the same as muscle mass. While muscle memory can help you regain muscle mass faster, it doesn't mean that your muscle cells literally "remember" the exercise. Instead, it refers to the ability to regain muscle mass in previously trained muscles.

Muscle memory is also called epigenetic memory
Epigenetic memory is a type of muscle memory that is stored on a molecular level. A study published in the journal *Medicine & Science in Sports & Exercise* found that muscles can store memory from past resistance-training sessions for up to 20 weeks. This means that if you take a break from training, you will be able to regain old muscle and strength in no time.
However, it is important to note that muscle memory does not have to do with your muscle cells "remembering" exercise. As your muscles are trained, the number of muscle fibre nuclei, or myonuclei, can increase as muscle mass increases. This is why you may notice a slight decrease in strength after one or two weeks off training, but it takes approximately four to six weeks of not bodybuilding for your muscle mass to decrease.
A recent study on mice further supports the idea of muscle memory. In this study, mice were trained for eight weeks and then did nothing for 12 weeks, which equates to about 10% of their lifespan and years for humans. After 12 weeks, the mice began training again and, despite three months of inactivity, they got stronger much more quickly than the first time.

Muscle memory can be studied in mice
Muscle memory is the ability to regain muscle mass in previously trained muscles. It is not about your muscle cells "remembering" exercise. Instead, as your muscles are trained, the number of muscle fibre nuclei, or myonuclei, can increase as muscle mass increases. This means that, if you lose muscle mass after taking time off from training, you can regain the muscle mass faster than the amount of time it took to put it on in the first place.
Muscle memory also takes place in the brain.

While muscle memory is often associated with strength training and bodybuilding, it can also be applied to other skills. For example, if you learn to play the piano and then take a break from practising, muscle memory will help you regain your skills faster than when you first learned them.
