The BUILT Masterclass on Mental Rehearsal delivers an evidence‑backed, step‑by‑step protocol for high‑performers who want to train a regulated version of themselves before real‑world pressure arrives. It contrasts common outcome‑focused visualization with the sport‑psychology tradition of motor imagery, introducing the core premise of functional equivalence: vivid imagined action activates the same neural circuitry as actual execution. The masterclass explains the neuro‑physiological basis (motor cortex, cerebellum, basal ganglia, mental chronometry, physiological responses) and links it to active‑inference theory and Maltz’s self‑image ideas. It reviews empirical findings, noting that mental practice reliably improves performance—especially when layered on existing skill—and that its strongest effects are on skill refinement, strategic cognition, confidence, anxiety management, and preparation, while it does not replace physical conditioning or work for people lacking vivid imagery. Internal (first‑person, kinesthetic) versus external (third‑person, visual) imagery is clarified, with internal imagery recommended for rehearsing regulated states. The five functions of imagery (cognitive‑specific, cognitive‑general, motivational‑specific, motivational‑arousal, motivational‑mastery) are outlined, emphasizing that the latter two are most relevant for state training. The PETTLEP model (Physical, Environment, Task, Timing, Learning, Emotion, Perspective) is presented as a seven‑element checklist that maximises functional equivalence. Individual differences in vividness and controllability, including aphantasia, are addressed with training suggestions. The masterclass separates well‑supported science (functional equivalence, PETTLEP efficacy, performance gains) from overstated claims (pure outcome visualization, magic‑like effects). It maps mental rehearsal onto the BUILT B‑U‑I‑L‑T framework (Break survival patterns, Upgrade operating system, Imagine next self, Let go of charge, Transcend identity). Practical daily instructions (5‑10‑minute PETTLEP‑rich rehearsal, process‑over‑outcome focus, catching negative rehearsal, pre‑performance priming, building vividness, combining with real practice) are provided. Key take‑aways are listed, and further study resources are suggested. The tone is instructional, evidence‑driven, and encouraging, aiming to equip readers with a concrete, scientifically validated mental rehearsal protocol for regulated performance.
