The Definition Early Extension occurs when your hips and pelvis thrust forward toward the golf ball during the downswing, pulling you off your original "tush line" (posture).

When your lower body moves closer to the ball, it completely destroys the space your arms need to swing freely. To avoid getting stuck, your brain forces you to stand up, raise the handle of the club, and flip your wrists to save the shot. This panic move results in weak blocks, snap hooks, and thin strikes.

The Amateur: Crowding the Strike

Watch the video below to see what Early Extension looks like in a position-by-position 3D breakdown.

The Data Check: We measure Early Extension by tracking the pelvis at the exact moment of impact (P7). Positive numbers mean the pelvis has thrusted forward toward the ball.

At impact, this amateur has thrusted their pelvis forward +2.4". They have physically closed the gap between their body and the golf ball by two and a half inches. With their hips blocking the path, their arms are jammed, forcing them to violently contort their hands just to make contact.

Stop Guessing. Start Measuring.

Do you Early Extend? Often called "goat humping," this is the most common fault in amateur golf, yet it is nearly impossible to feel yourself doing it in real time.

Upload your swing video for a Digital Analysis. We will use 3D motion tracking to measure your exact pelvic thrust at impact to tell you definitively if you are clearing your hips or crowding your arms. [Button: Start My Swing Analysis]

The Professional: Clearing the Hips

For comparison, watch how a Tour Professional rotates deep into their hips to maintain their space at impact.

The Data Check: At impact, this professional’s pelvis measures at +1.5".

Look at the Professional Acceptable Range:

• Pelvic Thrust (At Impact): -0.9" to +1.7"

The Pro stays well within the acceptable range. Instead of thrusting their mass forward toward the toes, they push their lead hip backward and around. By keeping their glutes back on the "tush line," they preserve a massive pocket of space. Their arms can fully extend through the ball without any interference, creating effortless speed and compression.

The Body-Swing Connection

Early Extension is almost never a choice—it is a physiological survival mechanism. There are 13 physical limitations that can impact your golf swing.

If your body physically cannot rotate while bent over, it will force you to stand up and thrust forward to complete the swing. The physical limitations that directly cause Early Extension include:

• Limited Hip Internal Rotation: If your hips can't turn deep into the socket, they have nowhere to go but forward.

• Inability to Deep Squat: If your ankles or calves are tight, you cannot maintain the flex needed in your lower body during the downswing.

• Weak Glutes and Core: Inability to stabilize the pelvis while rotating at high speeds.

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