The answer would probably lie in the golf muscles of a shorter golfer. It doesn’t necessarily mean you have to go out and bench press 400 lbs everyday. By exercising your upper and lower golf muscles two or three times a week, you can make a world of difference. The golf muscles that need to be exercised would be the legs, thighs, and whole upper portion of the body. The upper portions of the body are the main coil of the golf swing, with the arms and wrist getting the most exercise. As these same muscles are used most to guide and control the weight of the golf club through the motion of the golf swing. The lower portion of the body is strengthened to reinforce the upper portion of the golf swing. There are many books and videos on the Internet that address these exercises.
Golfers that prefer to exercise outdoors and are not sure of the appropriate exercises to use should take the exercise out on the practice range hitting golf balls. By hitting golf balls at the practice range, you will be exercising the important golf muscles naturally, and greatly improve your golf swing at the same time. Have you heard of golf muscle memory? It is a part of the brain that remembers a movement. Putting it another way, have you felt a muscle say, stop right there? This same part of the brain will tell moving parts of your body how far you can take it, so you do not injure yourself. It also signals for the timing of certain muscles to kick in and take over, if your latter part of the brain were paying attention. It would also remember good habits and bad habits in the golf swing. One must be careful in their practice routine on avoiding the bad habits. Practicing regularly will exercise these certain muscles and train them for further swing improvement in proper moves and timing. Your golf muscles will take the golf mechanics and timing to a higher level of power by exercising them over and over again.
