Procedural memory is a type of implicit memory (unconscious memory) and long-term memory which aids the performance of particular types of tasks without conscious awareness of these previous experiences.
As you repeat the behavior in the same context, the information is reorganized in your brain. It shifts to the sensory motor loop that supports representations of cue response associations, and no longer retains information on the goal or outcome. The more routine a behavior becomes, the less we are aware of it. Procedural memories are accessed and used without the need for conscious control or attention.
For example, once you know how to ride a bike, you wouldn't forget how to do it. Muscle memory appears instinctive.
