While it is true that strength is needed when you play golf, you should not overlook the fact that how exactly you swing is more important. Hitting the ball harder is not the only thing either that can improve your golf swing, you may also use items like power bands to help you achieve proper balance and coordination for a perfect swing. Yes, you can still hit the ball far without minding good swinging techniques but it most likely land on either side of the fairway. Additionally, relying only on strength when swinging will most likely get your wrist or back injured after a while.
