Golf is a game of rhythm and balance. If a player takes the winter off or misses a week or more in the season, just visualize your motion. Be it through simple meditation (or mental preparation) that when you go to the tee you will confidently left your body flow the same direction as the club is going. For right handed players that means that the weight goes right side , left side. Back to the target, belt to the target. If you got that…swing your swing!
Don’t worry about it. You can play !
