Doesn't sound like there's much of a reason to change anything, really.
But if you did at some stage
, then I'd suggest checking out Paul Carter's routines, and Off Road's log as well (the percentages and stuff are in there somewhere). I think BtB has done a similar kind of training as well, at some stages, though I could be wrong there. Also, the actual "Beyond 5/3/1" routine (i.e., *not* a 5/3/1 variant) is not all that different, IIRC. And that was the only vaguely "5/3/1"-like thing I ended up liking at all
, fwiw (doing squat, bench, and deadlift every session, three times a week, in my case).
Basically, you ramp up (after a few warmup sets of more than one rep) with singles, until you're at a given percentage, or perhaps you keep going higher if you're feeling very strong (depending on the routine in question), then drop down to a lower percentage for your actual working sets (e.g., 3x8 or whatever).
Well, that's the gist, but like I said, maybe check out those things if you're curious. And naturally, I'm not claiming that I know what's best for you (or even myself!
) - just some stuff I've seen, and also tried, that seems to be relevant to your question. Hope it's helpful in some way. Best of luck, whatever you decide.
