Muscle memory emerges through associative learning. Once you master a new motor skill, it becomes unconscious and an individual is unlikely to forget it. The more routine a behavior becomes, the less we are aware of it. Examples of muscle memory are found in a lots of daily activities that become automatic and improve with practice, such as swimming, riding a bicycle, playing a musical instrument, martial arts or even dancing. This process decreases the need for attention to detail and creates maximum efficiency within the motor and memory systems.
