Loading training plans…

Boring But Big adds substantial supplemental volume to Jim Wendler’s 5/3/1 strength work. After the main lift, you perform five sets of ten at a lighter load. The repeated work is the defining feature: this is a strength-and-size template for lifters who can recover from more than a minimal routine.

Who this plan suits

Choose it if you know the barbell lifts and want a clear way to add muscle-building work. Four lifting days are used in the example below. The supplemental squat and deadlift sets can be demanding, so an established habit of training and recovery matters more than the programme’s simple appearance.

Schedule and workout structure

The tables show the opening five-repetition week. The first three sets are the main 5/3/1 work; the following five are the lighter supplemental work. Follow the author’s training-max percentages and later-week changes. The assistance exercises and their fixed repetition counts below are training.fit choices within the template, not a unique mandatory selection. The calculation describes this week.

A

Exercise	Sets	Repetitions
Standing barbell overhead press	3	5, 5, 5+
Standing barbell overhead press	5	10
Cable Lat Pulldown	5	10

B

Exercise	Sets	Repetitions
Deadlift	3	5, 5, 5+
Deadlift	5	10
Reverse Crunches	5	10

C

Exercise	Sets	Repetitions
Bench Press	3	5, 5, 5+
Bench Press	5	10
Cable Lat Pulldown	5	10

D

Barbell Squats	3	5, 5, 5+

How progression works

Main lifts progress through the selected 5/3/1 cycle. Use a training max and begin the supplemental work conservatively. The author suggests roughly 30% of the training max for people new to BBB, with heavier supplemental loads developed over later cycles. Do not add a large accessory programme on top simply because the exercise list looks short. Conditioning should fit your goals and recovery.

What the science says

A dose-response review associated higher weekly volume with gains but also diminishing returns. BBB’s added sets increase the workload; the review does not show that its exact five-by-ten prescription is optimal. ^[1]

Concurrent aerobic and strength training were broadly compatible in a meta-analysis, while explosive strength could be affected. That finding does not guarantee unlimited conditioning will fit a high-volume lifting template. ^[2]

These papers examine training principles and prescriptions. They do not establish that 5/3/1 Boring But Big is superior to other well-designed programmes.
