My Game Has Changed Forever…Peter Finch’s TPI Lesson
Dr. Greg Rose and Dave Phillips at the Titleist Performance Institute (TPI) conduct a comprehensive physical and technical analysis of Peter Finch's game. By utilizing 3D motion capture and dual force plates, they identify a 'fake load' in Peter's backswing caused by poor trail ankle mobility and S-posture. The lesson focuses on correcting Peter's kinetic sequence, specifically teaching him how to properly load his trail leg and use the lead side to 'brake' and accelerate the trunk.
Physical limitations, such as restricted ankle mobility, can force technical flaws like early hip turn or S-posture.
Efficient power transfer follows a specific kinetic sequence: Lower Body -> Trunk -> Arms -> Club.
A 'fake load' occurs when the trail leg straightens too much, preventing the golfer from shifting weight effectively and often leading to fat iron shots.
Braking is crucial: The lead side must stop lateral movement to convert energy into rotation and speed.
Practicing with a 'plugged-in' athletic posture helps stabilize the core and prevents the loss of posture during the backswing.
