There's a program called PPP (Progressive Poundage Program), link: http://ptcfrankston.com/progressivepoundageprogram.html
It's designed to run for 11 weeks to reach a desired weight, for example I'm doing the 160kg squat program and the 105kg bench program.
Normally you'd squat on a monday, bench on a wednesday and deadlift on a friday, train the lift once a week, following this program, i.e. week 1 you do week 1 of the program, week 2 you do week 2 etc, all the way up to week 11.
For the first 6-8 weeks it's like 5 work sets per session and then in weeks 8-11 it bumps up to 6-7 work sets.
I want to do more volume so I simply do the following weeks in the same session do get the volume.
So if you look at my most recent bench session, the red is week 3 I think from memory (which is what I'm up to), then I also did week 4 (the blue) and week 5 (the purple, maxing out on the last 2 sets and an extra max set at 60kg).

In the big squat session I did a few weeks back, I did 5 weeks worth of PPP lifting. I don't follow the program strictly but use it more as a guide to the bare minium I want to be doing each week, and then do however more I feel like on the day. I've got 2 bulging discs in my lower back (no deadlifting for a while) and some days my back is great, others not so great, so it influences how I train, i.e. heavy, or more volume with a lighter weight etc. I enjoy lifting and don't do it for any set goal or competition, if I take it too seriously then it just becomes a chore, but that doesn't mean I don't train seriously when I'm in the gym, if that makes sense?
Some notes on my training: I train Monday, Wednesday and Friday. Alternate between squats and bench press, and then do some assistance work after depending how I feel and how much time I've got as some sessions go well over an hour. What this means is one week I'll bench twice and squat once, the following week I'll squat twice and bench once, so it's good to give the body a rest like that whilst still training hard.
