The Complete Guide to Wendler's 5/3/1 Program

Jim Wendler’s 5/3/1 is one of the most enduring strength training programs ever written. First published in 2009, it’s built on a simple idea: start light, progress slowly, and never miss reps. That philosophy has carried thousands of lifters from intermediate plateaus to legitimately strong totals — and it works precisely because it resists the urge to do too much too fast.

If you’re past the novice stage and looking for a program you can run for years, this is the guide you need.

The Philosophy Behind 5/3/1

Most programs fail because they ask you to push maximally every session. Wendler’s approach is the opposite. You train sub-maximally, wave your intensity over three-week cycles, and push hard on one set per session — the AMRAP (As Many Reps As Possible) set. The rest is controlled.

Three principles define the program:

Start too light. Your working weights are based on a training max, not your true max. This builds momentum and prevents early burnout.
Progress slowly. You add 5 lbs to upper body lifts and 10 lbs to lower body lifts per cycle — roughly monthly. That’s 60–120 lbs per year.
Break personal records. Every session gives you a chance to set a rep PR on your top set. That’s how you know you’re getting stronger.

The Four Main Lifts

5/3/1 is built around four barbell compound movements, each trained once per week:

Squat — the foundation of lower body strength
Bench Press — the primary upper body push
Deadlift — the ultimate posterior chain builder
Overhead Press (OHP) — the most honest test of upper body pressing power

A typical weekly layout:

Monday: Squat
Tuesday: Bench Press
Thursday: Deadlift
Friday: Overhead Press

You can shift the days to fit your schedule. What matters is that each lift gets trained once with adequate rest between sessions.

The Training Max: Your Starting Point

This is the concept that makes 5/3/1 work. Your training max (TM) is 85–90% of your true one-rep max. Every percentage in the program is calculated from this number, not your actual max.

Why? Because sub-maximal training lets you accumulate quality volume, maintain technique under load, and push hard on the AMRAP set without grinding through ugly reps. For a deeper dive on setting your TM correctly, see our training max calculator guide.

The 3-Week Wave Structure

Each 5/3/1 cycle runs three weeks. The rep scheme and percentages shift each week, building in intensity while reducing volume:

Week 1 — “5s Week”

Set 1: 65% x 5
Set 2: 75% x 5
Set 3: 85% x 5+ (AMRAP)

Week 2 — “3s Week”

Set 1: 70% x 3
Set 2: 80% x 3
Set 3: 90% x 3+ (AMRAP)

Week 3 — “5/3/1 Week”

Set 1: 75% x 5
Set 2: 85% x 3
Set 3: 95% x 1+ (AMRAP)

The “+” means you do as many reps as you can with good form. This is where you set rep PRs and gauge your progress.

The AMRAP Set: Where Progress Happens

The AMRAP set is the heart of 5/3/1. On week 1, your top set is 85% — a well-trained lifter might hit 8–10 reps. On week 3, your top set is 95% — you might hit 3–5 reps. Both are valuable data points.

Rules for the AMRAP:

Stop with 1–2 reps in the tank. Wendler doesn’t want you grinding to failure. If the bar slows significantly, rack it.
Track your reps. This is your primary measure of progress. If you got 7 reps at 85% last cycle and 8 this cycle, you’re stronger — period.
Don’t ego lift. A bad AMRAP set where you break form is worse than a conservative one.

Supplemental and Accessory Work

The main lift is only part of each session. After your three working sets, you add:

Supplemental work — additional sets of the main lift or a close variation. The most popular template is Boring But Big (BBB), which adds 5 sets of 10 reps at 50% of your TM.
Accessory work — push, pull, and single-leg/core exercises done for 25–50 reps each. This balances your training and addresses weak points. Our accessories guide covers this in depth.

After Each Cycle: Increase the TM

At the end of every three-week cycle:

Add 5 lbs to your upper body TMs (bench and OHP)
Add 10 lbs to your lower body TMs (squat and deadlift)

That’s it. No complicated periodization adjustments. No percentage recalculations beyond the TM bump. The simplicity is intentional.

Over a year of consistent training, that’s 60 lbs on your bench and OHP training maxes, and 120 lbs on your squat and deadlift training maxes. Slow progress is still progress — and it compounds.

When to Reset Your Training Max

If your AMRAP sets start yielding fewer than the prescribed minimum reps (e.g., only getting 3 reps on “5s week”), your TM has drifted too high. The fix:

Take your current TM
Multiply by 0.90 (reduce by 10%)
Use that as your new TM
Resume normal progression

This isn’t failure — it’s the program working as designed. Resets build in long-term sustainability.

Who Should Run 5/3/1?

5/3/1 is ideal for:

Post-novice lifters who have exhausted linear progression (if you’re still adding weight session to session, you probably don’t need this yet — see our 5/3/1 vs Starting Strength comparison)
Busy adults who train 3–4 days per week and want something sustainable
Athletes who need to get stronger without destroying themselves in the weight room
Anyone who values long-term progress over short-term PRs

It’s not the best fit for true beginners (who benefit from faster progression) or competitive powerlifters in meet prep (who may need more specificity).

Getting Started

Determine your 1RM for each of the four lifts (test or estimate)
Set your training max at 85–90% of that number
Choose a supplemental template (BBB is the most common starting point)
Pick your accessories (push/pull/legs-core, 25–50 reps each)
Run the three-week cycle, push the AMRAP sets, and increase TMs

The beauty of 5/3/1 is that setup takes 10 minutes and the program runs itself from there.
