Heres some advice he gave me a while back when I had squatted 550 in knee wraps at a meet.
"I spoke to Glenn today and he told me about this thread so I will put my two cents in.
Firstly the above advice is very good in my opinion. Your a 250kg (550lbs) squatter right now but does that mean you could hit 550 any day your fresh or does that mean you have hit 550 once after a good taper/rest week?
I ask this because it makes a big difference if your "peaked" for a big lift versus being able to come in and hit pretty much maximum any day.
I would take it in three steps
1. Start just like Glenn said don't try to organize it so much and don't do down sets until you can hit near maximum weights, meaning 25lbs or less from 550, on your maximum days. Keep your lighter days 50lbs less than the heavy days and work on closing the gap between the heavy and light days by adding weight to the light day each week or so.
2. Once you can hit maximum weights on your heavy days and the light days are basically the same then you usually hit some PR weights so try frequently until get really tired and you start to fail on the off days with weights you used to make regularly.
3. Once you fail a lot more on the off days then start pushing the maximum days but do some down sets like 5-10 singles or 5-10 doubles. Once a week I would do some kind of hard repetition type workout like 5x5 or something that adds up to 30ish reps or more.
This is what I would do if you squat 1-2 times a day 6-7 times a week.
If you squat more than that like 6-8 times a day 7 days a week you'll only be able to do maximum and sub-maximum lifts for 1-3 singles per workout. This is very effective but VERY hard.
I have squatted with both of these "templates" before and they work well but you need to have someone pushing you especially when you get really tired.
