Two things I've learned
I am a 'use it or lose it' guy
So, one thing I have realized is that if I don't lift heavy for a week or so, the first session I come back to it I am nowhere near where I left off. My first workout back, I may struggle with 85-90% of my work sets from before the break. I saw this today with my break from benching, but I have seen it many times. Also, even if I am lifting, if I don't do one rep/intensity combination for a while, that can go rusty. E.g. when I did Smolov Jr for bench, I added 5kg to my 1RM, but what I could lift for 5 reps actually went down a tiny bit, at least for sets across. Because all my 5 rep work on that programme was a 10-15kg lighter than what I had been doing before.
Fortunately, I *think* some of this loss is just temporary. When I squatted on Wednesday it was horrible and felt really hard and heavy. But today things felt back to normal, or maybe even slightly better. So possibly after a break, ramping up by about 10% to around 90% of work set weights before the break is probably a good first session back. I also think that I shouldn't take a whole week off. Just taking the Monday and Wednesday workoffs easy still gives me 6 days. Then Friday my 'getting back to it day'. Hopefully I won't get so rusty in the time off, but can still recover.
This suggests that something like T3, where over a week I am lift 10s, 5s and 3s will actually be very good for me.
I've got to Power Clean to Press
I have realized that there have been three times when I have pressed and the weight just felt horrible and heavy and didn't want to go up, and all three of those, I tried to press after taking the bar off the rack instead of power cleaning it. Last time, Wednesday, 50kg felt really heavy. But the Friday before I put 60kg up without that much more effort, and that time I power cleaned it first. It may just be a learned response as 90% of my pressing has been done power cleaning first. So, anyway, I need to always power clean it get it into the rack position. Anyway, even if it doesn't help me lift, it's much more awesome that way.
