We did these 3 weeks ago and I worked up to 455. I had the safety squat bar suspended in chains a little lower than I typically would have set it up, but it worked out well. This week I planned to hit 475 for a single.

Safety Squat bar (hatfield bar) Suspended (bottoms up) good morning
-For convenience I just count it as a 45 lb bar.
135x3
185x3
225x2
275x2
315x1
365x1
405x1
445x1
475x1

Easy enough!

Accessory work:
Reverse Hyper (light weight) 3x20
Cable Pull throughs *Heavy* 3x10
Standing cable abs 3x20

All things considered it was a good workout. The next couple weeks for my "deadlift" day (day to build up my deadlift) I plan to do a sumo pull off of high blocks next week, which I really, really suck at. And the following week I will pull a regular, conventional deadlift off of the floor for the first time in 2 months!

This is probably the longest I've gone without pulling a regular deadlift in the past 10 years. So, I will probably pull 700-725 and see how that moves and it will be a great indicator of where I am at!
