Boditrak Sports broadcast a presentation by Scott Hamilton, PGA with fantastic information using the Boditrak mat with numerous PGA Tour players. The COP traces were all linear and the guys worked on balance to keep the trace so pure. The large curved trace of some higher handicap golfers I work with came to mind. I wondered how I could train with them to drive a more linear trace, and came up with the idea of a stability pillow for the lead foot (a normal couch pillow would work too). As Scott says, the golf club follows the trace so the more linear we can make it the better we’ll strike the ball. What do you think?
