There's no memory stored in your muscles. What you call muscle memory is a neural pattern — and you're probably reinforcing the wrong one. EMG shows you which muscles actually fire, and when.
THE MYTH
You've heard it a thousand times. But repetition without knowing WHICH muscles are firing only deepens bad patterns. Two swings can look identical — but use completely different muscle groups.
Core drives rotation. Arms stay relaxed. Power flows.
Arms overcompensate for weak core. Same swing. Less power. More injury risk.
Both swings look the same on video. Only EMG reveals the difference.
THE TRUTH
Without feedback, your nervous system defaults to whatever muscle pattern "works" — even if it's inefficient or dangerous. You need to know what's actually firing to retrain the right pattern.
"Muscle memory" lives in your brain, not muscles. It's a learned firing sequence.
Surface electrodes detect electrical impulses as muscles contract — millisecond precision.
See which muscles fire. Correct the pattern. Build the RIGHT neural pathway.
EMG SCIENCE
No other consumer golf product offers EMG. We're the first to bring sports-science-grade muscle monitoring to your practice sessions.
Know exactly WHEN each muscle fires — within 5ms precision. Core before forearms? Or the other way around?
See how HARD each muscle group works. Overactive forearms? Underactive glutes? Now you know.
EMG amplitude drops as muscles fatigue. Know when you're practicing tired — before bad patterns set in.
