What does Success Rehearsal do to the body?
The body's response during Success Rehearsal has not been measured directly, but imaging of skilled performers suggests the practice likely raises activity in motor-planning regions like the supplementary motor area, the strip of cortex that sequences movements before the body carries them out (Milton et al., 2007). That same research shows heightened engagement of planning and attention networks during pre-performance routines, which practitioners often experience as a sense of having already run through the motions. Coordination between prefrontal planning regions and the memory-forming hippocampus is also expected to strengthen with repetition, felt as an imagined outcome becoming vivid and reachable (Yu et al., 2024). Because these directions are inferred from studies of expert athletes and general learning rather than measured during this practice, they describe an expected pattern, not a confirmed body change.
Prefrontal-Hippocampal Connectivity
moderate EVIDENCE
An imagined outcome can start to feel vivid and within reach, as if the mind is laying down a track it can later follow. Researchers expect this reflects stronger coordination between the prefrontal cortex, the brain's planning region, and the hippocampus, which builds and stores memories, based on studies of imagined future scenarios and repeated practice, though it hasn't been measured directly during Success Rehearsal (Yu et al., 2024).
