"You need to stay connected!" - but just saying it is not enough to understand what it means.
What "Staying Connected" Really Means
What it REALLY means is for your upper arms to move in unison with your torso. Basically being disconnected is having your arms and elbows moving off plane.
The Drill Explained
This article references an instructor from PCGolfSwing's YouTube Channel who explains how to effectively work the drill that Tiger Woods and others on tour do so often - swing with the golf glove under the arms.
Unfortunately, few of us really understand the purpose of the drill. We try it and give up quickly as it is very uncomfortable if done improperly.
Equipment Options
You can use a glove, a towel (Players Towel of course), or golf club. If you choose a golf club, do not try to hit balls. Place the club under your arms as close to your arm pits as you can. This is just to create a feeling of how the take away should feel.
Practice Progression
With the towel or glove, start with:
- Practice swings
- Chips
- Pitches
- Full swings
The key is to be slow and deliberate when practicing this drill. You will soon begin to understand what it feels like to be connected!
Note: This one takes time! If you do this drill properly, your swing will feel VERY short.
Making It Part of Your Routine
If you find a drill that makes a positive impression on your golf swing, incorporate it into your routine. Tiger Woods is the perfect example! Since he has been working with Sean Foley, you see him using the glove under the arm while taking practice swings during tournaments and, for a while, in his pre-shot routine.
He understands that repetition is the mother of skill. And, if you're willing to work and be diligent, that skill will become second nature!
