In order to analyze a skill such as the golf swing, we have to measure it. To do that we need one or more reference frames, also known as coordinate systems. Reference frames consist of a zero point and three perpendicular axes, usually called, the X, Y and Z axes, which originate from this origin. There is always one global reference frame from which everything else is … [Read more...]
Basic Biomechanics for Golf: Selected Golf Topics
Recently, in the Facebook golf groups there has been a lot of interest in basic biomechanics principles, so I thought I would post this document. I originally wrote it last year for the LPGA to be incorporated as part of their Integrated Performance System. It presents selected topics on basic biomechanics principles for the golf swing. The topic covered … [Read more...]
My PhD Dissertation
I am finally able to publish my PhD dissertation on my website.

I actually started my PhD at Arizona State in 1992! I did one year and then started Skill Technologies and then AMM. So life got in the way and … [Read more...]
Pelvic Thrust Biofeedback using AMM3D Golf
This video discusses the pelvic thrust graph in AMM3D with TPI reports. I explain the basics of the curve and then look at an actual example of a golfer with excessive early extension and how we help her fix it using biofeedback drills. If you don’t have an AMM3D system there is still a good drill to help this problem. Put the back of a folding chair behind you at address, … [Read more...]
