Squats and presses

Yesterday I worked on squats. I warm up pretty much just by starting to squat, so I do a lot of warm-up sets before the work set:
5 @ 20 kg;
2 x 5 @ 50 kg;
5 @ 60, 75, and 85 kg
Work sets: I wanted to do 2 x 5 @ 90 but I managed 1 x 5 then 3, 2. I was happy with that because last time I tried to do five reps at 90 kg, I bailed after three.
Pressing: worked up to 3 then 2 @ 35 kg, then 1, 1, 1, 2, 1, 1 @ 37.
I’ve pressed 42 before (months ago) and I want to work back up and get to 45 by six months from now. Maybe it won’t take very long? I don’t know what to expect.
