Serious competitive bowling, i.e. at the pro level, whereas one bowls with a 15 or 16 lb. ball around 70-75 games per week (practice and competition games), is extremely tough on the body, such as the fingers, bowling hand, bowling wrist, bowling elbow, bowling shoulder, back (especially the mid-lower back), hips, knees, ankles, and feet take an absolute beating week in and week out.
Although golf does exert a certain amount of stress on the body, it is not nearly as physically destructive as bowling.
Golf to me is stress relieving, hit the ball and walk, whereas bowling is stress inducing, throw the ball and watch/feel the body suffer (if throwing several games).
