Woodshedding
"Woodshedding", or shedding, is a term commonly used to describe the act of practicing some endeavor, usually in private, to improve one's proficiency in performing it. It is typically used by musicians to mean rehearsing a difficult passage repeatedly, until it can be performed flawlessly. The term is used metaphorically where "the woodshed" means any private place to practice without being heard by anyone else. This is based on the assumption that an actual woodshed would likely be in a remote location, away from the main house. The term is also used in other contexts.
