I’ve always asked students if they work out or more importantly if they stretch and encourage them to at least stretch if not more. I also work with and recommend a friend who is TPI certified for anyone with physical issues or wanting to get on the right program to improve.
I think fitness is a must for three reasons.
1. If you’re not flexible, and most men are not, then you are not going to be able to do things in the golf swing that you want to do.
2. If you’re not strong in the legs, then late in the round when you get tired you won’t have the stamina to finish the round as well as someone who is.
3. Core, upper body, shoulders and arm strength will not only help create more power and speed but also help to prevent injury.
I’m 69 years old, I stretch every morning, lift weights at least twice a week and will ride a road bike almost 3000 miles this year. I’ve got 4 bulging and one herniated disc in my lower back so stretching is a must, the rest I do to stay in shape, hopefully prolong my life and keep my weight down.
By the age of 40 you should make a decision on how you are going to manage your health, diet, fitness, etc. If you do your game will be better but most importantly back issues, heart attacks and the like will be much less apt to happen.
