Try to get out and walk or run 3 or 4 miles every day, or at least 5 or 6 days per week.

I agree with this.

I have not done a PFT run since I was in the Air Force in the mid 1970's. I did run a 5k 2 or 3 years ago. Went out too fast and did the first 2 miles in 13:30. Not too bad for 60 years old. All of my training before that race was at 9:30 to 11:00 minutes per mile, with most runs at about 10 minutes per mile.

Impressive!
