Hi Titus,
I'm back to a strength training program now.
It's amazing to me how bodybuilding-style hypertrophy training will make your muscles bigger, but ultimately not make you as strong.
The general public would think bodybuilders would be the strongest, but that's not the case at all.
I beg to differ. Ronnie Coleman, Arnold Schwarzenegger, and the late Franco Columbu were BOTH world-class bodybuilders and powerlifters.
Lou Ferrigno was a World's Strongest Man competitor (as was Columbu). The recently-departed Bill Pearl made more money as a professional strongman (bending iron bars, tearing phone books, blowing up hot-water bottles, etc.) than he did winning the NABBA Mr. Universe 4 times.
Sergio Oliva was on Cuba's Olympic weight lifting team, before defecting to the United States. And more recent examples of strength and size include that Larry Wheels fellow. Not to mention, Johnnie Jackson, who frequently did both powerlifting and bodybuilding shows during his career. He won a deadlifting contest, just weeks before turning pro at the NPC Nationals.
I was surprised at how much of a weakling I was with respect to my body weight.
Walter Sobchak was 100% right.
So I'm doing a 20-week strength building program right now to get my deadlift back to the 505-525 range.
It shouldn't be too much of a problem, as muscle memory alone will get me over 80% of the way there - but I want to try to hit a personal record. A 550 deadlift would be nice, but I'll be satisfied with 500+. In fact, 495x5 will be fine. Anything beyond that would be a bonus.
Thank you for the support, Titus. If you have a bodybuilding "bro" diet for me, I'm all ears. I'm no longer in a hurry to make gains anymore. I can take my time and do it naturally. I just wanted a little boost for the summer. 
I know I'll get back to the 500-lb range for deadlifts, but 550-lb at <185-lb would be amazing. I think anything around triple body weight for deadlift is a very high standard to hold.
Also Titus - if you happen to have a strength program for me, let me know. Due to the pandemic gym closures, and having spent the past few months training bodybuilding-style for my cycle, I'm a fresh template right to gain my old strength back. If I could get 10% beyond that, I'd be thrilled. But how difficult that will be will depend on whether or not I want to keep my body weight higher. At 170, deadlifting anything over 525 would be hard.
Here is a little deadlift workout I did last night, just to see where I was at. I'll start a refined strength program next week. If you have any advice or tips, let me know.

You don't weigh 170 lbs anymore. So why are you worried about that? Bodybuilders and powerlifters, as they improve, they usually go UP a weight class. It's not as if you're going head up with 300 pounders.
