nSuns 5/3/1 guide: high-volume training without spreadsheet chaos
nSuns attracts lifters who want the 5/3/1 training-max idea with more weekly volume and faster progression pressure. The same thing that makes it appealing also makes it easy to mishandle: there are many sets, many percentages, and a lot of places for the spreadsheet to become the workout.

How to build this in Protocol
Use Protocol as the execution layer, not the program source.
- Use the original source for the rules, then build the routine and run the sessions in Protocol.
Protocol can
- Save the routine as named days, exercises, sets, rest notes, and load anchors.
- Guide workouts exercise by exercise and set by set while logging completed, failed, and skipped work.
- Apply configured weighted progression, failure-threshold load reductions, and equipment-aware rounding when those rules exist in the routine.
Protocol cannot
- Protocol does not import spreadsheets or pass calculator values into the Training app automatically.
- Protocol is independent from named program owners; source material and coaching override this guide.
- No built-in preset is claimed for this page unless the page says so directly.
Manual setup
Calculate your inputs
Use the original source for the rules, then build the routine and run the sessions in Protocol.
1. Pick the first input: tested max or e1RM, then a lower training max.
2. Use the calculator: start with Training max calculator.
3. Run the block: build the routine in Protocol after checking the source rules.
How nSuns works
nSuns is a community-popular, 5/3/1-inspired linear progression program. Public references commonly describe 4-day, 5-day, and 6-day variants, with the main lifts organized around a training max and a high number of percentage-based sets.
A typical nSuns session has a primary lift and a secondary compound lift. The primary lift uses a heavy top-set pattern with back-off work, while the secondary lift usually gives another main movement or close variation enough volume to drive practice.
The program is not official 5/3/1. It borrows ideas from Wendler-style training maxes and rep waves, then adds its own high-volume weekly progression. Use the community source or app version you trust for the exact day layout and set table.
This guide explains the concepts and helps you calculate your own inputs. For the official program, read or buy the original source.
Weekly structure and progression
The common versions run four to six days per week. That usually means squatting, pressing, benching, deadlifting, or a close variation appears more than once across the week.
Progression is usually weekly rather than monthly. If the top-set performance supports an increase, the next week moves the training max or programmed load up; if the session breaks down, the lifter needs a clear record before changing the next week.
This is where spreadsheets become both useful and annoying. The targets may be correct, while the session still feels hard to follow when you are tired, changing plates, and trying to remember which set is next.
Starting loads and calculator inputs
Start from conservative training maxes, not best-day maxes. A small overestimate can turn a high-volume week into a survival test before the program has enough evidence to adjust.
Use a recent e1RM if you do not have tested maxes, then reduce it into a training max before building the week. The training max calculator, plate calculator, and warm-up calculator are the useful chain here.
Protocol does not include a built-in nSuns preset and does not import nSuns spreadsheets. Enter the routine manually from a legitimate source, then use Protocol to run the configured days set by set.
Example session shape
A practical nSuns day starts with the main lift for the day, moves through the programmed percentage work, then uses a second compound lift or variation for more volume. Accessories come after the programmed barbell work.
The exact set sequence belongs to the source you choose. The execution principle is safe to describe: primary lift, secondary lift, accessories, log the top-set result, then let that record inform the next week.
Execution traps
Common mistakes
- Starting with too much volume before building tolerance.
- Copying spreadsheet numbers without understanding the training max.
- Ignoring failed sets because the sheet keeps calculating.
- Changing accessories so often that the log stops meaning much.
- Letting the top-set result disappear instead of using it to understand the next week's load.
Common questions
FAQ
Is nSuns official 5/3/1?
No. It is commonly described as 5/3/1-inspired. Use Jim Wendler's material for official 5/3/1 and trusted community or app sources for nSuns-specific layouts.
Can Protocol run nSuns?
Protocol can support a user-authored nSuns-style routine when the days, sets, targets, and progression rules are configured manually. There is no built-in nSuns preset today.
Should beginners run nSuns?
The high volume and complexity usually make it a better fit after a lifter already understands basic barbell progression.
What should I calculate before starting nSuns?
Start with recent max estimates, reduce them into conservative training maxes, then calculate the plates and warm-ups needed for the first week.
