BBB Assistance Weight?

Hi guys, about BBB and assistance works.

So the main core lifts (1 each day) have their weights set according to the 5/3/1 plan. For example there’s the assistance bench press on Monday, first month it should be 5x10 with 50% of the rm, right? 2nd month it’s 60%, 3rd month 70%. On Thursday the bench press is the maib lift, so it should be done with the 5/3/1 weights, is that correct?

2nd question - assistance work following assistance work. What weight should I use with those? Enough to do 10 reps of, for example, biceps curls? And then progress with the weight next month?

Welcome to the forums.

The answer to (what I think is) your question depends on whether you’re doing “traditional” BBB or the 3 month BBB challenge. The first stays at 50%, the second increases every cycle.

In either case, the week is structured like this:

Squat day:
Squat 531 %
Squat 5 x 10

Bench day:
Bench 531%
Bench 5 x 10

Deadlift day:
Deadlift 531%
Deadlift 5 x 10

Press day:
Press 531%
Press 5 x 10

How strong are you currently?
Do you have the appropriate books for the program?

Edit: apologies, missed the second question. Accessories do not need to have a progression model, just do some and move on with your life.

I’m going to start the 3-month challenge. Ok, so it’s going to be 50% of the assistant work first month, 60% 2nd and 70% in the 3rd month.

By how strong you mean my max weight for the core lifts?

I’m going to order books, but it might take a while till I receive them.

Just a rough number to indicate strength levels and experience levels is fine. And an indication of the TM you intend to use.

I prefer 55-60-65%, like FSL but one step under.

Ok, so my max is:
OHP: 50kg (standing, barbell)
Deadlift: 110kg
Bench press: 80kg
Squad: 110kg

TM’s going to be 90% of those maxes above.

Hey guys, I’m during the 4th week of the 5-3-1 Boring Bug Big program. It’s deload week now and I’m thinking about the new cycle that’s coming up and increasing the weights. According to the book, I should increase the training max of the lower body lifts by 10 pound and the upper body lifts by 5 pounds, right? It’s the training max, not RM? When I put these numbers in the excel table (I use kgs instead of punds) I get very small weight progress, almost 1-2 kgs. Is it ok?


Remember your TM is a tool to increase strength, not a sign of how much strength you’ve gained.

Unrelated but: Depending on your recovery, you may be able to string two 531 cycles together in future without a deload in between.


Thank you for your help!
