How the lower body works in the golf swing depending on if you're an upper, mid or low core player.

In the golf swing there are three ground reaction forces that are used in this order by almost every Tour player; lateral, rotary, and vertical. The lateral force peaks first, rotary second then lastly verticals kick in. We simply shift, rotate and jump. I have been using Wright Balance now for over six years to determine if someone is an upper, mid or low core player. Over 90% of my students have been upper core, 9% mid-core and only 1% low core. Mid core is your average Tour player swing with their hips rotated 40-45 digress at impact. Upper core has the least hip rotation at impact and low core has the most ala Dustin Johnson.
Each core region uses these ground reaction forces in different percentages. Upper Core players use verticals the most and laterals the least. That's why we stand up, come out of posture and our hips are not very rotated at impact. (Me in picture above from the 1990's) Low core players use laterals the most and verticals the least. That's why their hips are the most rotated at impact and their weight is toward their heels at impact. (Can't jump very high from out of your heels) Mid-core players use all three ground reaction forces similarly.

Excellent analysis Larry. I must be upper core or upper/mid. My hips rotate to where my back faces the target with almost no lateral movement. I pivot with left leg/heel up on backswing and right leg/heel up on follow-through.

Most of us are upper core. Keep Swinging!

Hi Larry, what pivot would be the best for a golfer with lower back pain? Thanks and enjoy all of your
video's.

[@LarryRinkerGolf]

I would consult your doctor and the best pivot would be one that matches your dominant core region. Keep Swinging!

@@LarryRinkerGolf Thank you Larry.
