My motivation is longevity, functional strength, and being able to recover from shit when I'm old. Not to mention the positive effect strength has on balance for old people. I'm not going to be one of those guys who is otherwise healthy but goes down due to a broken hip in my late 70s.
I have to admit I am wallowing in regret the last few weeks. I was a strong lifter way back in my early 20s, and I quit and did sedentary work. I was slapped with a reality check this summer, when I had a hard time lifting a fucking 2x12x12 for a deck.
Now in my mid 40s, I am learning that I can make good gains, but I am more prone to injury from lifting - as well as the slow recovery compared to a younger guy. It's frustrating as hell, because I could easily spend the time in my gym every day from a motivational aspect (I do 5x5 every other day) and I absolutely love my time in it. Makes me wonder why I waited so long to finally quit being a fatass.
I think I have a fairly significant shoulder injury, I don't know when it happened but may have been OH press or bench. Seems like a rotator cuff or torn labrum. This is very depressing, because the thought of having to take 6 months off post surgery to heal would really piss me off. I want to get back to the total I was at in my youth (~1200 or so) within a year if possible. Tired of being weak, waking up with a stiff back and achy knees from doing a little bit of physical work.
I have seen some gains but the shoulder is pretty damn discouraging. Right now I am stubbornly working through it (no pain during the lifts, just at night afterward) and trying to work around it a bit with good form.
