The example was for me to ‘try’ to attain his A9 position with weight forward, chest high and wrists not turning over. I’m not as flexible as Zack and won’t likely ever get there, but we rehearse past our ability to move in that direction.
When I have a bad round going, I just think of the rest as practice. We did stop after 12 holes a few weeks ago, but that was because my friends back started hurting and the round was very slow. Even when I’ve been hurt, I try to finish the round and just ease off the rest of my swings.
I was playing with @billchao in Maine a few years back and my left leg stopped working due to a meniscus injury. I was wear a brace at the time too. We still finished though.
