Improving your golf swing isn’t just about feel - it’s about facts. That’s where OPTIMOTION comes in. By tracking your movement in 3D, OPTIMOTION shows what’s really happening in your swing and helps you unlock more distance, consistency, and speed.
In this lesson, Mark Crossfield dives into one of the most overlooked concepts in golf: arm depth. With OPTIMOTION, he uncovers how small adjustments to arm depth and shoulder turn can create a big difference in ball speed and power.
Let’s break it down.
What is Arm Depth in the Golf Swing?
Arm depth refers to how far your lead arms move across your chest during the backswing. Many golfers think more depth equals more turn - but that’s not always true. In fact, too much arm depth can make the swing look longer while actually costing you speed.
OPTIMOTION makes this clear by comparing swings side by side, showing whether your arms are working with your body turn or simply faking it.
How Does Arm Depth Affect Swing Speed and Distance?
This is where the data gets interesting. When your arms move too far behind you, the swing often loses structure. The result? Lower clubhead speed and less distance.
By reducing arm depth and keeping the hands in a stronger position, you create more stretch between the upper and lower body. That stretch is the key to building power and unlocking extra yards.
Why is Shoulder Turn Important in the Golf Swing?
Many golfers think they’re making a big shoulder turn, but OPTIMOTION proves otherwise. Amateurs often rely on arm movement across the chest instead of actually rotating their shoulders.
A proper shoulder turn:
- Creates a width in the backswing
- Builds torque for more power
- Sets up consistent contact
With the right turn, you’ll generate the kind of ball speed that translates to more distance without swinging harder.
How Can OPTIMOTION Measure and Improve Your Golf Swing?
Unlike guessing, OPTIMOTION shows your swing in precise detail: shoulder rotation, hip turn, arm depth, and more.
This real-time feedback helps you:
- See exactly what your body is doing
- Compare your moves to tour averages
- Focus on changes that deliver real results
It’s not about making your swing look different - it’s about making it work better.
