Just out of curiosity how bulked are you Neil? And how lean? Body lard has always fluctuated a bit for me, one of my harder battles, but I'm happy to keep it under 15. I've given up close grip pressing after some rotator cuff grief but have no problems - so far - with a parallel grip or a decline press. My mecanno elbow isn't too bad but it needs scrupulous warming up first.
Just getting old and creaky I guess.
Well I'm never gonna be a lightweight - been lifting since 85, so being skinny ain't my problem. I'm probably around 15% right now, but having a little more time for training, means I'm doing more cardio. Ideally, I'd like to maintain 10-12% year 'round. I don't always get that. The past year, or so, haven't been good for me, health wise, but the last few months have seen me be able to put in more time, and try and put my health and fitness a much higher priority.
Probably the first 8-10 years I was training, I would have probably considered myself a bodybuilder, then. I came from a background of martial arts in my mid teens, so when I first hit the iron, I wasn't entirely untrained. After that, I gravitated to boxing (not really competitively, though, not sure my endeavours could be considered that successful, there...). Some of that has always carried with me, in terms of other training I try and do (skip a lot, and do bag work as and when).
Strength wise, well I've never truly been in the powerlifting camp. Although I spent a good, solid amount of years making the big 3 the cornerstone of my training. As you, I've got some issues with rotator cuff - both shoulders - but can be helped with some specific exercises, and avoided things that aggravate - what I find is there's certain types of lift, or equipment, that cumulatively and progressively, as you tend to improve your poundages when returning to something - cause me a lot of shoulder grief and pain. So now, I work around them, avoid the things I know aggravate it. I bought a decent book about shoulder biomechanics, injury, and remediation some time back - and that, and lots of research and doing has helped me get to a point where I don't really miss the things I select not to do to avoid issue.
I've always enjoyed and embraced full squats. For some reason I could never get along with the leg press - I always felt squats suited me more, anyway. Slightly aside, but I first started doing single-leg-press around the early / mid 90s. But the only true, back injury I've had in the gym, with any true legacy, has been through heavy leg press. It's all to easy to round your lower back, especially if you're inclined to do more than 6 inches of travel. And that's what happened to me, some years back - got carried along with the hormones and ego, and pushed too hard, injured my lower back on the leg press, and the only time I've had issue with my lower back when squatting heavy, has been since then. Fortunately, SLP - asssuming suitable leg press equipment, rather non-intuitively, is probably the least risk of injury, but potentially capable of significant loading - and used by skaters and cyclists when training.
That said, it's still good to get under the squat bar - you don't get that many who squat - or at least do full squats, these days. I've never wrapped, though, and don't use a belt (well not in recent times - but like everybody in the 80s, I tended to wear one in the gym for everything!) and since injuring my back on the leg press some years back, and in a more minor fashion, trying to hit some decent weights (for me) under the squat bar some time after it, I've always been a bit slow and steady about loading up the bar - but then I don't have the impetus as much, because I don't have to hit the poundages and compete like you will have to. I find I can push increase in poundages in SLP, which then over time carries over in greater leg power in squats.
These days, I probably split focus half-and-half between weights, and some form of cardio. In terms of the types of poundages, well like many, who've trained a fairly long time, there's a certain, residual strength and level you tend to sustain. But I've had to learn in recent years, that as you age, it's so much easier to get injured, so much easier to remember your bolder, stronger years, and so much harder and longer to recover. So now I have to mitigate that, in the types of poundages I pursue. I have that luxury, though, even though sometimes ego tries to get the better of you - as a competitive powerlifter, I recognise that you don't.
Thing is, I'm not a bodybuilder, I'm not a powerlifter, I lift because I always have done, I suppose I'm at a reasonable level of strength compared with people who've trained as long, and similar build. These days, though, I'm as equally focused on fitness and health - that wasn't something I bothered about when younger - although that said, I never dabbled with PEDs - which explains my deep interest in nutrition and science on the subject - but all the same, when I was younger, I just went to the gym lifted, didn't really think that much about how healthy I was - just how I performed, and I suppose from a vain perspective, how I looked. Having had a hard year in terms of health, I've become very much more focused on actually being healthy and fit, too - rather than that just being a pleasant side effect.
I think where training is concerned, it's something I've done for (rather scarily) nearing 30 years. But then I like that, and I like longevity. Sometimes, my commitment hasn't always been consistent - sometimes, my training has been very hit and miss, and my fitness and bodyfat levels haven't always been great. But I've been doing it for a long time, and still want to be doing it for a long time - I have this, I suppose rather romanticised, view of still hitting the iron when I'm well into my 60s and 70s (as I saw the odd individual over the years) as a sort of lifelong commitment thing. Given I've been doing it for this long, perhaps it's not unreasonable - but recent times have shown me very much how we can all be at the mercy of illness for some things we very much take for granted.
Keep strong, buddy.
