Golfers are some of the most stubborn people. Most of them stick to their sport and do not want to try anything different. But if you try other sports, you can only learn from the experience.
Especially if it is another sport with a club or a ball. So today you will not be playing golf but try something new. I recommend something slightly similar to golf and most importantly something you have never tried before.
Things you could try can be tennis, squash, baseball, hockey, ice-hockey, cricket, badminton, disc golf or anything else you have not tried yet, but find interesting.
The most important thing is that it must be completely new to you. By trying new sports regularly you will get a better feeling for your body and see how the different sports are related. You will be surprised, how much you can actually learn for your game of golf in other sports.
It gives you a new look onto things. And because you are trying something new you will make a lot of mistakes, but also learn a lot of new things fast. I consider myself being pretty fit. But I find it always fascinating how a new sport engages muscle groups I did not even know I had.
Then I get really humble again. Because only when you try a sport you can really acknowledge what those top athletes are able to do and what amount of work they put into that. If you feel stuck with your improvements of your game or swing, trying a new sport an mix it up and free your mind. I personally recommend to try at least two new sports each year.
If you can bring some golf buddies with you, you can have even more fun. Who knows, maybe you discover a new passion next to golf. The worst thing that could happen is that you find out that a particular sport is not for you.
