You may think you are too old to get fit and strengthen up. This is not the case. Just remember to begin slowly with simple routines you can easily handle .
Here is an every day example of a golfer who now has fun.
I once taught a gentleman who was older, he had hardly ever golfed before and had enrolled for a six-hour series of lessons. He was very stiff, with very limited range of movement and consequently could barely make contact with the ball. Despite his challenges, he was enthusiastic, he practised between lessons, started walking regularly and performing a series of home exercises/stretches I prescribed for him. After the sixth lesson (seven weeks) he could made contact with the ball and get around just well enough to enjoy a round of golf.
After the lessons I didn’t see him at the driving range for about 4 months. When he reappeared I could not believe his improvement! He had developed a nice fluid golf swing, achieved good distance and was really happy. I asked what he had done extra to achieve such outstanding results. His answer was “nothing different”. He just kept up his exercises and played regular golf. He admitted to me that we he first began he was so stiff he could really only start the stretches I had taught him while still in bed, before getting up in the morning. Still, this tiny start was what was responsible for him loosening up his body up enough to enable the beginnings of a good golf swing. Look at the fun he has now!
The video of Gary Player is a fantastic example of what is possible for some senior golfers. Don’t expect these kind of results, be motivated by them!
