My pre round routine includes stretching for 45-60 minutes. Starting with my neck, shoulders, wrists, upper & lower back, waist, thighs, calves, and ankles/feet. I’m 64 years old and walk each round, so I’ve made stretching a must before playing to feel ready to hit the course and give myself the best chance to play to my full potential. Once I arrive at the course, I putt for 10 minutes, chip around for 10 minutes, and full swing for 20-30 minutes.
