Muscle memory is basically your nervous system learning a shortcut the first time you do something correctly. Hit that same motion over and over with good form, and the brain starts to expect it. Hammering until it hurts just wears out the tissue and can break that shortcut. Try slow, controlled reps to let the brain build the pathway, then slowly increase the load. Your wrist is buzzing because it’s asking for a break—give it some rest, then keep at it smartly.

Sounds solid—slow start, then step up the load, but only when your wrist is ready. Treat each rest as a puzzle piece, not a penalty. Keep the form tight, and you’ll finish stronger than you started.
