The biggest mistake made by many corporate golfers is to rush straight from the office out onto the course. Too frequently, they will hit their opening tee shot into trouble (either into the trees or out of-bounds) and wonder where it all went wrong. Often, it sets the mood for the entire round.
What they don’t realise is that they’ve adapted their body into a bad posture from sitting behind a computer screen, and they’ve taken that fixed, rounded posture into their setup for the golf swing (above). That flexed foetal position shuts down a lot of your performance muscles and causes a reduction in the rotation that is essential for the golf swing.
