The Putting Isolation Drill

Place the TrueStrike between your biceps just above the elbows, level with your sternum. Use your elbows to hold it snugly in place, then grip the putter normally. The pad's position locks the arms to the chest, forcing the stroke to be driven entirely by the upper chest, shoulders, and upper back. Any independent arm or hand movement — or any lower body involvement — will cause the TrueStrike to shift or fall, giving you immediate feedback that the wrong body parts are controlling the stroke.

According to Jacob Tilton, nothing below the belly button should move during a putting stroke. The legs, hips, and lower body should remain completely still, serving as a stable foundation for the upper body to rock the putter back and through. Any lower body movement introduces variables that change the path, face angle, and low point of the stroke — all of which directly affect start line and distance control. The TrueStrike held between the biceps enforces this stillness by making the upper body the sole driver of the motion.

The upper chest, shoulders, and upper back are the largest muscle groups involved in the putting stroke — and larger muscles are inherently more consistent and controllable than smaller ones. A wristy or armsy stroke relies on fine motor control that breaks down under pressure, on fast greens, and across long putts. A shoulder-driven stroke uses gross motor patterns that hold up in competition because they're less susceptible to tension and nervousness. This is why Jacob — and most tour-level putting instructors — teach the stroke as a shoulder rock rather than a hands-and-arms motion.

True roll refers to immediate, skid-free forward rotation on the ball from the first inch of its journey. It requires centered face contact, a square face at impact, and a slightly ascending or level strike. When the putting stroke is driven by the large muscles of the upper chest and shoulders — rather than flicking hands or active wrists — the face stays square longer through impact, contact is more consistently centered, and the ball rolls end-over-end immediately rather than skidding before settling into rotation. True roll makes distance control significantly more predictable.

As Jacob points out, 30–40% of all golf shots are putts — meaning putting is the single largest contributor to your score on any given round. The average recreational golfer takes 36 or more putts per 18 holes, while tour professionals average closer to 28–29. Even a modest improvement of two to three putts per round — well within reach with a more consistent, isolated stroke — translates directly to lower scores faster than any full swing improvement. The TrueStrike isolation drill targets the most efficient path to those saved strokes.
