Before starting your training with TrueGroove, you will need to understand how to set it up for your particular swing plane type. There are two basic types of swing planes, and your setup will differ depending on which one you use.
Which Swing Plane Type Are You?
The vast majority of golfers, roughly 85%, use a two-plane swing. In a two-plane swing, the arms travel on a steeper plane than the shoulder turn. Two separate movements, two separate planes.
The remaining 15% or so use a one-plane swing, where everything moves as one unit, flatter and more around the body.
If you are not sure which category you fall into, start with the two-plane setup below. Most golfers do.
Setup for the Two-Plane Swing
Take your address position with a 7-iron. Loosen the dial and slide the legs to set the Poly-Glide Plane Rail angle so that it intersects with your sternum at address, then tighten the dial. That is your starting point.
From there, the natural geometry of your set takes over. Longer clubs will produce a flatter plane angle; shorter clubs will produce a more upright one. That is exactly how it should work. The sternum reference point keeps everything calibrated to your body, not just to the club in your hand.
We recommend starting every session with your 7-iron. It sits in the middle of the set and represents the most balanced plane angle for training purposes. In fact, many TrueGroove users do the bulk of their practice work with a 7-iron and see the benefits carry over throughout the bag. Once your body learns the correct motion, it transfers.
Setup for the One-Plane Swing
If you use a one-plane swing, the sternum-based setup described above will feel off immediately. That is normal, and it is actually a useful signal. One-planers swing with the arms and shoulders on the same plane, so the plane angle needs to reflect that.
Rather than referencing your sternum, place your 7-iron on the ground with the sole flat. Loosen the dial and slide the legs to set the Poly-Glide Plane Rail as close to that shaft angle as possible, then tighten the dial and adjust from there based on feel.
A Note on the Power Bar
Regardless of swing type, the Power Bar remains your checkpoint for early extension. The horizontal bar sits at approximately glute height. Your goal is to maintain contact with it throughout the swing. If you separate from the Power Bar, that is your body telling you it is moving toward the ball rather than rotating through it. The plane rail corrects the path; the Power Bar corrects the body.
Start Simple, Build From There
Do not overthink the initial setup. Get your plane angle in the right zone, pick up your 7-iron, and start moving. TrueGroove gives you immediate feedback. If something feels forced or mechanically awkward, the Poly-Glide Plane Rail likely needs a small adjustment. Dial it in over the first few swings and you will find your groove quickly.
