The distance a 70-year-old should hit a golf ball depends on many factors, such as the type of club being used and the golfer’s strength and flexibility. Generally speaking, an average male senior golfer can expect to hit a driver around 170 yards, while an average female senior golfer can expect to hit one around 140 yards. Seniors must remember that hitting too hard or improper technique can lead to injury, so it is best to start slowly and gradually increase power as they become more comfortable with their swing. With practice and patience, seniors can still enjoy the game of golf.
