Stop Guessing. Start Measuring.
Your Swing Is Data.
Learn To Read It.
The modern golf swing is built on kinematics and ground reaction forces, not platitudes and "feels." We break down the exact data points that separate scratch golfers from high handicappers.
Kinematic Sequence Breakdown
Feel isn't real. Data is.
For decades, golf instruction relied on visual estimation and subjective feeling. "Keep your head down." "Swing easy." Today, force plates and 3D motion capture reveal the truth: power comes from the ground, sequence dictates efficiency, and precise wrist angles govern the clubface. Data of Body (DOB) training bridges the gap between what you think you're doing and what physics proves is happening.
Ground Reaction Forces
Vertical, braking, and torsional forces. The ground is your only source of leverage.
Read GRF GuideKinematic Sequence
Pelvis, torso, arms, club. The specific order of acceleration and deceleration determines speed.
Analyze the SequenceWrist Angles (Flexion/Extension)
Bowed or cupped. Your lead wrist dictates the dynamic loft and face angle at impact.
Fix Your FaceThe Pro vs. Am Divide
The data paints a clear picture. The difference between a tour pro and a 15-handicapper isn't just time spent hitting balls; it's mechanical efficiency measurable in degrees and Newtons.

Frequently Asked Questions
Do I need expensive sensors to use this data?
No. While a Trackman or force plates are ideal, understanding the concepts allows you to film your swing (even at 240fps on a phone) and identify major flaws in sequence and wrist angles.
What is the most important metric?
Smash factor is the ultimate arbiter of impact efficiency, but it is a result. The cause is usually found in the kinematic sequence—specifically, how well the pelvis decelerates to whip the torso.
The Golden Number
A smash factor of 1.49 on a driver is practically perfect. It means for every 1 mph of clubhead speed, you generate 1.49 mph of ball speed. If you swing at 100mph but your smash is 1.35, you're leaving 30 yards on the table purely due to off-center strikes and poor physics.

Read the Biomechanics GlossaryThe Myth of "Keep Your Head Down"
Trying to keep your head perfectly still restricts pelvic and thoracic rotation. The data shows elite players allow their head to move down and away from the target in transition as they load into the ground.
Why "Swing Easy" Costs You
Swinging "easy" usually ruins the kinematic sequence. You need aggressive braking forces to snap the kinetic chain. Intent to swing fast is required, but it must be sequenced correctly.
