How has your fitness routine evolved as you've aged?

I’m 71 and try staying fit by going to the gym three times a week. Bicep curls 25 , 27 1/2 , 30 , 32 1/2 , 35 lbs 10 reps each . Bench press 180 , 190 , 200 , 210 lbs 10 reps each . Lateral bar I can do from 130 to 165 . Dumbbells shoulder press I’m up to 60 lbs . I try to do 6-8 different exercises and also spend about 10-15 minutes hitting the heavy bag . I still weigh about the same as I did when I was in the Army . I am at 160 now and have been as heavy as 170 lbs .

I pace myself more so that I don't over exert myself too soon, thus whooping many mens' butts that are at least 10 years younger than I. I'm 38 now and am fortunate to still be able to run with my unit in the "A" group on Mondays, even after 13 years on active duty. So hard to believe that there are soldiers 10 years younger than me on permanent profiles already because of "bad joints" or what not.

I am 52 and do situps, pushups, squats, shoulder shrugs, and curls. I also walk. I am not as sprite as I use to be.
