Commit to a golf fitness program. Okay this sounds like a real resolution, but the fact is most golfers today are over taught and under trained. No amount of practice can compensate for a body that cannot perform the functional movements of the swing. Any honest instructor will tell you it makes no sense to teach a swing correction to someone who is physically unable to perform it. You need to get in shape to hit solid, more consistent shots, and attain long-term wellness on and off the course.
