So I've been working consistently for just under 5 months now, so perhaps it's time to take stock of progress.
Starting StatsBW - 76kg
Squat - 70kg x 4
Front Squat - 50kg x 5
Deadlift - 90kg x 2
Bench - 60kg x 1
OHP - 30kg x 8
Chins - BW x 5
Current StatsBW - 84kg
Squat - 112.5kg x 3 [done 13-06-17]
Front Squat - 97.5kg x 3
Deadlift - 130kg x 4 [done at RPE~8 most recently]
Bench - 87.5kg x 4
OHP - 57.5kg x 3
Chins - +15kg x 4
So that's 8kg gained in 5 months. Some amount of that is likely due to creatine. I'll measure my waist in the morning, too, to see if that's changed much.
https://www.strongerbyscience.com/realistic-training-goals/ suggests 3kg of lean mass in one's first three months as an average: "a “normal” range [for beginners] from .5kg/1lb per month to 2kg/4lbs per month." So I've probably hit the middle of that pretty well, which is pleasing.
Lifts are all near the best they've ever been. I checked back through old logs and my OHP PR is 60kgx1, which I should definitely be able to match or beat. I never repped 100kg on bench, so I reckon I'm at my peak there too. Squats less good, but lower body stuff has been impaired by occasional lower back pain. However, I'm happy with how I'm managing that and expect I will be at lifetime PR levels for that in the near future. I think my FS best was around 110x3, which I'll be at pretty soon.
According to symmetricstrength.com I'm at intermediate ("the lifter has been consistently training, likely for at least a year") on everything and all my lifts are fairly well in line with each other.

I would love to get to "proficient" by the end of the year.
Went through a lot of stress in this period with a horrendously intense final term of university where I had to take 24 hours of exams + job searching and whatnot, so all things considered I think this progress is pretty good going. Mental state-wise I'm having a really great time training and looking forward to sticking with it.
I'm going on a 10ish day holiday soon, retuning early August. I'll be training with a good buddy a few times during that span, maybe trying out maxes on some of the upper body lifts. After I return I think I'll commit to a cut. I'm not substantially fluffier than when I started working out again, but I'm now at a decent level muscularity and strength and think I could feel a lot better getting down to 75-78kg. I've never successfully got particularly lean in the past, but I've grown up rather a lot since previous training periods and the fact that I am a decent cook nowadays will make life a lot easier. I'm actually quite excited to try this out. If I cut at about .75kg/week then it should be about a 10 week cut. I think doing it now makes sense, because I'm probably still at the point where I can cut moderately aggressively and still make decent progress on gym lifts.
Anyway, glad to be back here and back in the gym.
