The Kinematic Sequence

The secret to effortless power is a highly efficient transfer of energy from the lower body to the clubhead.

The 1-2-3-4 of the Downswing

Data from 3D motion capture systems shows that every tour professional, regardless of their swing style, follows a specific order of deceleration to transfer energy:

1. Pelvis: Initiates the downswing, accelerates, then rapidly decelerates.
2. Thorax (Chest): Takes the energy from the pelvis, accelerates faster, then decelerates.
3. Lead Arm: Takes energy from the thorax, accelerates, decelerates.
4. Club: Receives all accumulated energy, releasing maximum speed at impact.

If you sway or fail to shift weight, your pelvis cannot decelerate properly, ruining the entire chain. The Bump and Fire drill fixes this directly.
