Happy Summer everyone!
Today I wanted to feature a post written by Matt DeJohn that I have used for reference numerous times.  Like within any specialized topic, there are certain references used to make communicating more effective and more universal.  A lot of golf swing conversations use references from Homer Kelley’s book The Golfing Machine and MORAD’s – Mankind’s Objective Research and Development – (via Mac O’Grady) 10 positions of the swing.  I’ll let Matt explain the rest as he does a great job here.  Thank you Matt for condensing these different references all into one spot.  To find out more about Matt, visit his website and his Facebook page.

Positions, Pressure Points, And Power Accumulators

Resource Page for the positions and power package (Pressure Points, and Power Accumulators).

Positions:

P1- Address

P2 – Club shaft parallel with the ground (Back swing)

P3- Left arm parallel with the ground (Back swing)

P4- Top of back swing

P5- Left arm parallel with the ground (Down swing)

p6- Shaft Parallel with the ground (Down swing)

p7- Impact

P8- Shaft Parallel with the ground (Through Swing)

p9- Right arm parallel with the ground (Through Swing)

P10- Finish

The Ps are used to classify the positions in the golf swing.  It makes it very easy to compare golfers swings.  It’s also a great way to show a player their progress in making changes.

Power Package:  PPs and PAs

“Force is applied to the Ball through the Lever Assemblies. Power is applied to the Lever Assemblies through Pressure Points. Power is applied to the Pressure Points by Power Accumulators”
– Homer Kelley “The Golfing Machine” 6-B-0

Pressure Points

PP#1- Right heel pad of hand against left thumb

PP#2- Last three Fingers of left hand

PP#3- Right index finger against shaft

PP#4- Left arm against chest

Golfers use different combinations of these pressure points.  A golfer who is referred to as a “swinger” because they’re left side is pulling the golf club primarily uses pressure points #2 and #4.  Golfers referred to as a “hitter” because they’re right side is pushing the club primarily use pressure points #1 and #3.

Power Accumulators

PA#1 – The bending and straightening of the right arm (muscle thrust)

PA#2- The cocking and uncocking of the left wrist (Velocity Power)

PA#3- The turn and roll of the angle established between the Clubshaft and the Left Forearm when you take the grip (Transfer Power)

PA#4- The angle formed by the left arm and the left shoulder (Radius Power)

For now I hope this is a good resource of recognizing the different pieces of the POWER PACKAGE and identifying the positions in the golf swing.  I may be adding more explanation at a later data.
