If folks are on a computer all day, every day, chances are their shoulders are rolled forward and their posture looks scrunched, slumpy. This can cause problems in the golf swing if left unchecked. I was shanking balls and could not figure out why...shanking out of nowhere. Then I remembered my golf instructor telling me my left shoulder was rolled forward and up vs. down and back, like with good posture at address. My right shoulder was also scrunched upward and rolled forward.
Now when I set up with good shoulder posture at address, then roll my shoulders forward, it's readily apparent that the club hosel moves towards the ball by about a 1/2 to 3/4 an inch, and there's no doubt in my mind that position leads to shanks, arm swings, and steeper downswings.
So now before I address the ball I stand straight, shoulders back and square (pushing my shoulders back and down), like a military guy ready to salute a general, then I tilt down to address the ball. I suggest trying this to see if it feels weird because it felt weird for me, or weird because bad posture/shoulders was "normal". A positive result is the good posture position promotes a shoulder-driven takeaway vs. arms, and my left arm easily stays straight like in the straight-arm drill.
Nice suggestion, @GolfLivesMatter. That computer posture you reference is a very real thing, and since most folks here in the school are likely on their computers...... well........ 😎
