What is the difference between 5/3/1 and 3/5/1?

3/5/1 runs the same weeks in a different order: the 3s week first, then the 5s, then 5/3/1. Wendler proposed it as a variation because it puts the heaviest AMRAP week after the lightest one, which some lifters find easier to recover from. The weights, Training Max, and progression are identical — this calculator's output covers both; just swap the order of weeks 1 and 2.

Should I run Boring But Big or First Set Last?

Both are supplemental templates layered on the same main work. Boring But Big (5×10 @ 50% TM, the toggle in this calculator) adds high-volume hypertrophy work and is the default choice for adding muscle. First Set Last repeats your first working-set weight for 3–5 sets of 5–8 reps — less volume at a higher intensity, better when recovery is tight or you mainly want strength practice. Pick one, not both.

How long should I run 5/3/1?

Treat it in blocks of at least 3–6 cycles (3–6 months) before judging it. The program is designed around small monthly increments, so its results compound: many lifters run it for years, resetting individual lifts when they stall. If you keep setting rep records on the AMRAP sets, there is no reason to stop.

Can I do cardio or conditioning with 5/3/1?

Yes — Wendler explicitly recommends conditioning alongside the lifting, with hill sprints and sled/prowler work as his classic choices, 2–3 sessions per week. Schedule hard conditioning after lifting or on separate days, and keep it from interfering with squat and deadlift recovery. Easy aerobic work (walking, cycling) can go almost anywhere.

Is 5/3/1 good for beginners?

It works, but it progresses monthly while a true novice can often add weight every session on a simpler linear program — so many beginners leave gains on the table starting 5/3/1 too early. It is a strong choice once session-to-session jumps stall, typically after 6–12 months of consistent barbell training. If you do start it as a beginner, be strict about the 90% (or 85%) Training Max, since new lifters usually overestimate their 1RM.

What do I do when I plateau on 5/3/1?

First check the basics the program depends on: an honest Training Max, the deload actually taken, food and sleep adequate. Then reset the stalled lift — drop its TM by about 10%, or recalculate from a recent AMRAP set using an e1RM, and build back up over the next cycles. Reset only the lift that stalled. Repeated stalls on the same lift usually mean the TM crept too high relative to your true max, not that the program stopped working.

5/3/1 Calculator (Wendler)

Enter your one-rep max — or estimate it from a recent set — and get every set of your next 5/3/1 cycle: warm-ups, working weights, AMRAP targets, and the deload week.

How the 5/3/1 Calculator Works

Three inputs produce your entire month of training: a max, a Training Max percentage, and the fixed 5/3/1 wave.

Start from a max

Enter your tested one-rep max, or a recent hard set of 2–10 reps and we estimate it (e1RM) as the average of the Brzycki and Epley formulas. An estimate from a solid triple or set of five is accurate enough for 5/3/1 — the program is deliberately not sensitive to a few kilos of error.

Set the Training Max

5/3/1 never programs off your true max. The Training Max (TM) is 85–90% of your 1RM, and every working percentage is calculated from it. Default is 90%, Wendler's standard recommendation; choose 85% if you are coming back from a break or your max is a guess.

Get the 4-week wave

The calculator lays out all four weeks — 5s, 3s, 5/3/1, then a deload — with the same 40/50/60% warm-up ramp before each session. Weights are rounded down to the nearest 2.5 kg or 5 lb so every set is loadable on a real bar, and the last set of weeks 1–3 is marked AMRAP.

The Principles Behind 5/3/1

Jim Wendler built 5/3/1 around a handful of ideas that look conservative on paper and are exactly why the program keeps working when more aggressive plans stall. Understanding them stops you from "fixing" the parts that make it effective.

Why the Training Max sits below your 1RM

Programming off 90% of your max means the prescribed weights are always weights you can actually lift, on a bad day, with good bar speed. That buffer is what lets you add weight cycle after cycle without grinding: your 1RM fluctuates daily with sleep, stress, and fatigue, but a Training Max at 85–90% stays under the worst-day ceiling. Lifters who inflate their TM get about three good weeks before every top set becomes a max attempt — which is precisely the situation 5/3/1 exists to avoid.

What the AMRAP sets are for

The fixed percentages are deliberately modest, so the last set of each week is where you earn progress: "5+", "3+", and "1+" mean you take the top weight for as many quality reps as you have that day. The AMRAP set does two jobs — it auto-regulates the stimulus (feeling strong: rep out; feeling flat: hit the minimum and go home) and it gives you a rep record to beat, which is a far more frequent and motivating measure of progress than a new 1RM.

Slow progression is the point

Adding 2.5 kg to a press and 5 kg to a squat per month feels trivially small — until you multiply it by twelve cycles. The increments are sized so the program stays ahead of you for years instead of weeks. Racing the TM up faster than your actual strength grows is borrowing progress from future cycles, and the debt always comes due as missed reps.

When to reset

When the minimum reps stop being there — you fail a prescribed 5/3/1 set, or the "1+" is a grinder with nothing behind it — you don't switch programs, you reset: drop the Training Max for that lift by about 10% (or recalculate from a recent AMRAP e1RM) and build back up. Lifts stall independently; reset only the one that stalled and let the others keep climbing.

Common 5/3/1 Mistakes

Setting the Training Max too high

The most common way to break 5/3/1. If your TM is based on an inflated or ancient 1RM, the percentages stop being sub-maximal, bar speed dies, and AMRAP sets shrink to the minimum. Rule of thumb: you should be able to hit your TM for 3–5 clean reps any day of the week. When in doubt, choose 85% — starting too light costs you one cycle, starting too heavy costs you the program.

Skipping the deload week

Week 4 feels like a waste when you're motivated — that is exactly when accumulating fatigue is easiest to ignore. The deload keeps the pattern trained while letting recovery catch up, so the next cycle's heavier weights land on a fresh base. Skip it repeatedly and the missed reps show up around cycles three or four, right when the TM starts getting meaningful.

Grinding every AMRAP set to failure

AMRAP means as many quality reps as possible, not a weekly max-effort test. Leaving 1–2 reps in the tank still sets rep records and drives progress, without the recovery cost of grinding to absolute failure every week. Save genuinely emptying the tank for occasional big days — for instance the last 5/3/1 week before a reset.

Quitting after three weeks

5/3/1 is built around monthly increments, so a single cycle proves almost nothing. The visible payoff — rep records falling at weights that used to be your top sets — arrives over 3–6 cycles. Changing programs every few weeks resets that compounding to zero, which is why chronic program-hoppers rate every program as "not working".
