I found it interesting to read and easy to relate to many of the posts above. Still I come in, again, with my old fart's perspective. I turn 64 in two months and live in semi-retirement in a huge, 70,000+ retirement community NW of Orlando. I originally lifted because my father introduced me to it making a barbell with a broomstick and two cement filled paint cans. Later he got me into my first gym, all the while my goals were a lot like those above. Now its a little bit different.
In my 40s and 50s I lifted to complement my running. From my late 50s and now my 60s I face a new world I never knew before and certainly was not prepared to face. As opposed to my youth, I now know, I will not live forever. So I lift:
1. For the woman I love who lives daily with her cancer and her emphysema. They told her she would die last year if she didn't give up smoking, change her lifestyle and exercise. The harder I train, the more success I have, the more she believes that we can still in our old age, change our bodies for the better. That's motivation my friends. And it is working!
2. I train for my dad, the 87 yeaqr old ex-fighter, Philly A's prospect, teamster, and best built man of his day in the Philly suburbs of long ago. Now crippled and near the end he takes pleasure and pride in seeing his "kid" build up and make heads turn as he once did. Every time I visit him I try to wear a tank top or some skin tight shirt and strut...yeah with the arms bulging....you betchum little beaver!
3. I train for all the great retirees I know and meet around here who have heard all their lives about "knowing not to overdo it at our age" and not "hurting yourself" with too much exercise. They need to see and believe that change is possible, that there are no limits other than the ones we either set upon ourselves or let others impose on us. They need to learn to believe!
4. I train for myself. I am not ready to "go quietly into the night". I will only go kicking and screaming and dumping tons of iron on any obstacle in my way. Concenting on my goals of growing bigger and stronger ( I was an emaciated, despondent 149 lbs in 2000 when I moved back here from Holland, now I am 214) I use my lifting as the vortex of an entire lifestyle of nutrition, relaxation, friendly like-minded male companionship, stress relief, libido maintenance etc etc etc. I tell people I am "middle aged" since I plan on hitting at least 100.
**And God forbid, but your grandkids may have to still put up with me here on AM when I make it to that century mark and report on how much I lifted that day in the gym!!
