Arm speed in the kinematic sequence should peak after shoulder speed but before club head speed — the final link in the proximal-to-distal energy transfer chain. Arm speed is NOT generated by pulling the arms; it is generated by the body decelerating (stopping or slowing rotation) and transferring momentum through the arms to the club. This is the whip analogy: the handle of the whip stops, and the tip accelerates. Golfers who try to create arm speed by pulling with the arms disrupt the kinematic chain, losing efficiency. GOATY ENGINE gate tracks the relationship between body deceleration and arm/club acceleration — the signature of efficient power transfer.

Frequently Asked Questions
What is Arm Speed in golf?
The velocity of the arms through the downswing, which should peak just before club head speed to maximize the whipping effect.
Why does arm speed matter for scoring?
Arm speed in the kinematic sequence should peak after shoulder speed but before club head speed — the final link in the proximal-to-distal energy transfer chain. Arm speed is NOT generated by pulling the arms; it is generated by the body decelerating (stopping or slowing rotation...
How can I improve my arm speed?
GOATY ENGINE gate tracks the body deceleration and arm acceleration relationship — the signature of efficient whip-like power transfer. GOATY AI measures your arm speed in real time during live practice sessions — giving you instant feedback without needing to film and review video after the fact.
