How does repeated practice help a skill become easier?
A new movement may demand close attention. The brain must coordinate which muscles act, when they act and how strongly they act. Each attempt also produces sensory information: what the movement looked like, felt like and achieved. Repeating a skill gives the nervous system more opportunities to connect commands with their results.

Feedback can reveal differences between an intended movement and what happened. Adjustments on later attempts can make coordination more reliable. Learning involves changes in interacting networks, including systems involved in movement, sensation and memory. It cannot be reduced to one pathway becoming stronger every time an action is repeated.
Practice is only part of the process. During rest, some patterns of activity associated with a newly learned movement can recur. Research on a finger-typing skill found that brief rest periods were associated with gains between attempts. This finding helps explain why the nervous system can continue processing a skill while the muscles are no longer performing it.
A smoother attempt does not by itself prove a lasting change. Tiredness, attention and temporary adjustments affect performance too. Retaining a skill after a delay provides different evidence from doing well during practice. Improvement varies across people, movements and conditions, so repetition does not create a fixed amount of learning.
