The Definition A Loss of Posture occurs when a golfer loses their initial spine angle during the backswing, typically by standing up, lifting their chest, and raising their head away from the golf ball.

When you stand up in the backswing, you drastically increase the distance between your chest and the golf ball. To make contact on the downswing, your brain will force you to artificially "reach" for the ball by casting the club, steeply chopping down, or early extending. It makes compressing the golf ball nearly impossible.

The Amateur: Losing the Angles

Watch the video below to see what a Loss of Posture looks like in a position-by-position 3D breakdown.

The Data Check: Notice the numbers tracking the chest and head. By the time this amateur reaches the top of the backswing (P4), their chest has lifted +4.9" and their head has lifted +4.0".

They have physically moved almost 5 inches away from the golf ball. For context, the professional average for chest movement is actually a negative number (meaning they stay level or compress slightly downward). By lifting up, this amateur has completely destroyed their ability to strike the ground in the same place twice.

Stop Guessing. Start Measuring.

Do you lose your posture? It is incredibly difficult to feel yourself standing up by 2 inches, but the golf ball knows immediately.

The Professional: Staying in the Shot

For comparison, watch how a Tour Professional maintains their body angles to the top of the swing.

The Data Check: At the top of the backswing, this professional’s chest has actually lowered by -0.8" and their head has lowered by -1.4".

Look at the Professional Acceptable Ranges:

• Chest Vertical Movement: -2.1" to +0.5"

• Head Vertical Movement: -3.6" to -0.6"

Pros do not stand up. They stay in their posture or compress slightly into the ground to load their legs. This keeps their distance to the golf ball perfectly constant, making a pure strike a simple mathematical outcome rather than a lucky timing maneuver.

The Body-Swing Connection

Losing your posture is rarely just a "bad habit"—it is heavily tied to physical limitations. There are 13 physical limitations that can impact your golf swing.

If your body is unable to move in certain ways, your swing will naturally compensate. The physical limitations that directly force a golfer to stand up out of their posture include:

• Tight hamstrings and calves (inability to maintain a hip hinge)

• Limited thoracic spine (upper back) rotation and extension

• Weak core and glute stability

A simple screening process can identify these limitations and provide a straightforward exercise routine to unlock your swing.
