I think when it comes to actually testing your maxes, you have to test your maxes.
Ill work up to 280kg, that I know I can get.
Ill throw on 300, that I should probably get.
Ill then load 310 for a 2.5kg PR and see what happens.
Depending how 310 feels I might call it a day or Ill throw more on, ideally 317.5kg
Thanks for the reply
This is what I do, but I’m weak and don’t compete, I assumed things could be different if these things weren’t true.
Im just not convinced that reverse engineering an estimated 1rm from something like a 5rm will actually give you good idea of what happens at the sharp end. For me my actual 1rm’s are higher than my e1rms because i have pretty poor muscular endurance.
Its not uncommon for peoples e1rm to be much hgiher though, because of form breakdowns at 95%+
I’ve been over 60kg out before, albeit from very high rep touch and go deads. My form is atrocious at any weight though, i can’t say it gets much worse near maxes. Thinking about it, I may look to address this when I test maxes around Christmas, are you ok for me to tag you in to the videos for feedback?
For sure, always happy to help
@Pinkylifting You see they came out with the Sheiko Gold app? I think it was you that mentioned you may hop on that when it came out.
Absolutely, I think it’s still Beta, and only for IOS. Android wil be delayed. I new id regret switching from apple eventually
Whomp whomp. No bench PR
Prep week 1
Day 2 (skipped day 1, was feeling ill)
Still feeling a bit shitty, arguing with myself all day about whether to lift or not, fuck it I’ll see what happens.
Bench
140 x 1 - fine, not as easy as it should be
150 x 1 - fine, same thing
160 x 1 - not a great grove, but moved
165 x 1 - moved about as slow as I’d want without a spotter
Fuck it I’m here, lets see how 172 feels
172.5 x 0 - whomp. Moved about half an inch off the chest 
High bar
185 x 1
205 x 1
Called high bar there, had more in the tank but I wanted to save any energy for a low bar PR
Low bar
225 x 1 - no wraps, moved ok
240 x 1 - wraps, moved slow.
About to attempt 250.
Nice surprise to salvage something from the shitshow of a session
250kg x 1.PR
Some crazy numbers in here! Great work.
That went, pretty well.
Deadlift
220 x 1
250 x 1
280 x 1
300 x 1
310 x 1 - PB
317.5 x 1 - PB, 700lb milestone.
325 x 1 - PB, 17.5kg PR.
Honestly I was tempted to go up, but I had already been greedy going for more than one, luckily the gym had just closed.
Guest pass to a powerlifting gym about half an hour from me, so I can post vids when I have WiFi.
A huge lift in unfamiliar territory! Great job!
Holy shit dude. Color me impressed as fuck.
Today’s top set. Had to take a knee at the end because I felt more than a bit dizzy

Dude that went up super fast. Did not look like a massive PR or very hard! Congrats man. Anymore videos include thick chick in the top right? 
Very strong lady that, she competes in the same federation as me actually, with her beast of a bf lol.
Looks like I need a new title for my training log. 700 has been and gone.
Congratulations Pinky! Time to update your first post, yeah?
Forgot I had those, nice to see some good progress markers
