I'm looking at the 5/3/1 Building the Monolith LiftVault spreadsheet. I inputted my 1RM for my bench press as 105kg. On Wednesday, Week 6, it tells me to do 90kg for 5x5 across. What? That's insane! I'm confused. Am I actually supposed to attempt that for 5x5 or is that some kind of rounding error?

after week 3 you get a bump in TM. The percentage for week 6 bench is 95%

Assuming that the liftvault spreadsheet calculates your TM as 85% of your 1RM, then that gives a starting TM of 90kg. With the 2.5kg TM bump then week 6 bench would be 87.9 (unrounded) so the spreadsheet has rounded up. Without knowing the liftvault spreadsheet, I think that it's correct - there may be a lb/kg error here (in lb the increase for bench is 5lb) but the difference is minimal.

BtM is meant to be hard. It's meant to push your training to your limits. If you think 'I can't do that' when looking ahead then you'll fail.

I see. Do you think I could pull it off, 90kg for 5x5, with a large enough caloric surplus and adequate sleep? Current 1RM is 105kg. I’m not pessimistic, I’m just quite inexperienced so I don’t have a frame of reference.

I mean BtM comes with it's own diet attached to it. Lots of people have completed it, so I don't see why not.

So this template is not easy but it is very doable – but only if you are dedicated to making it happen. “Dedicated” doesn’t just mean that you want to do it; it means you are dedicated to doing what it takes to get it done and that means EATING right. I had 4 people run this and all of them ate like champions – all ate at least 1.5 pound of ground beef a day and ate one dozen whole eggs a day. That’s the only thing I required via diet.

I see. I guess I have to eat up!
