You don’t have to run far. A few years ago, Was walking 2-3 miles a day and running about 200 meters twice during that period
I do 12 100 yard sprints ( really just a slow jog ), and 8 sets of 40 push-ups, three times a week.
The post exercise endorphin rush is a great bonus.
I’m almost 70 years old chronologically. But, I feel like I’m 29.
I run a mile every other day, and with my job and my normal nervousness walk a lot. I’ll be 63 in the spring. On the days I don’t run, I lift.
