Being 65 years old I like to be on the range 50-60 minutes before the tee time. Get to the putting green 1st. Lag some putts, Hit some mid-range putts and short putts under 5 feet. About 10 minutes. Hit the range, do some minimal stretching. Start with the PW, hit some mid-irons and then the driver. After that some sequence swings, hit the driver, then follow up with a mid-iron. Do the same with driver then PW. Do it several times. The chipping area is close by so spend the last 5 minutes chipping then off to the 1st tee.
