I still smirk every time I read the title/subtitle of the forum "Intermediate Training Logs: Justified or Not".
53 year old male here, in-between NLPs (finally got all of the home equipment mid-October and ran it until the New Year, then focused on snowboarding as I do every winter). I have been running a maintenance program through the winter to not lose everything, trying to get at least one set of intensity each week of the four main lifts, and knowing that I'll restart my NLP in the next few weeks with higher lifts than October, even with a slight reset for volume.
But I suspect that where I am now, I'll quickly run out my deadlifts, even after incorporating power cleans (which I love [you'll get there]). I think I can milk my squats a while longer by switching from 5x3's to 3x5's, but I may be looking to box squats soon after. Same with the press and bench. I do have a full set of micro-plates that I can creep upward with if I want to get really stubborn, but at that point, the volume of NLP 5x3's or 3x5's will be beating me up more than anything.
Like you, I'm not looking forward to jumping into more complicated programming. I like the predictability and simplicity of the NLP and I don't get bored by it. But I suspect that this year I'll have to deal with some intermediate programming. You'll get there too. Just don't feel rushed.
