My swing and ball striking have improved 10x in the past week. I read Ben Hogans little 5 steps to a golf swing book, and it just kinda made things click with me. I still have mishits and stuff because I've not completely committed everything to muscle memory, but I'm doing MUCH better. I took 6 strokes off my average for the course we usually play, and I'm hoping to improve another few today after taking another range trip.
I kept trying to mold my swing to what other guys were doing, but the fact is, I'm just over 6'3"...my swing plane isn't going to be like my 5'11" friends'.
Sometimes I still slump into almost a baseball type swing...but I'm starting to get away from it. Things I never thought about before reading the book were keeping my right elbow in, the proper way to shift my weight (i always thought the left knee didn't move at all) and how to turn my hips on plane, as well as keeping my arms closer together, and how to grip with my right hand, I always used my thumb and finger instead of my middle fingers. Things are getting better.
On top of all that, I now have 1/2" longer clubs, so it helps, too. Sometimes I still hit a ball wrong on the club face, or aim a little wrong, and it goes off target, but it's a good solid hit, rather than some awful 50yd slice.
