Your swing looks fine on camera. But the muscles tell a different story. EMG reveals the invisible compensation patterns that cameras — and coaches — can never see.
THE VISUAL ILLUSION
Camera-based analysis can only see joint positions. It misses the 95% of force that comes from internal muscle activation patterns.

Same positions on camera. 50 yards apart on the course. The difference is invisible to video.
COMPENSATION PATTERNS
Compensation is your body's workaround. The forearm takes over when the core fails to fire. The result? Same swing shape — less power, more injury risk, zero improvement.
Obliques fail to activate at the start of the downswing. The chain has no proximal driver.
Without core drive, the forearm activates early and hard to "throw" the club. Overuse leads to strain.
The kinematic multiplier drops from 5× to 2×. Distance drops 50 yards. Consistency drops. Frustration rises.
"Core activation is 31% when it should be 80%+. Forearm is compensating. Focus drill: oblique activation before takeaway."
THE CAUSALITY CHAIN
Every swing fault has a hidden root. The causality flows from muscle to motion to result. Only EMG captures the first link in the chain.
"Your shoulder didn't rotate enough."
Visible symptom. Not actionable.
"Your core fired at 31% — shoulder rotation wasn't driven. Activate obliques earlier."
Root cause. Actionable fix.
