Jim Wendler's 5/3/1 Program Explained: Complete Guide + Calculator
I almost quit 5/3/1 after two weeks because it felt too easy
My squat was at 130 kg and I was used to grinding near-max singles. When I calculated my Training Max and saw that my heaviest set in week one was only 110 kg, I thought the plan was a joke. I was leaving reps on the table. The weights felt light. My ego was screaming.
Then week three hit. The top set was 5/3/1+ at 95% of my Training Max - and I hit it for 7 reps. That AMRAP set showed me something no max-out session ever had: I was genuinely stronger than my numbers suggested, and the submaximal work had been building capacity I could not see session to session.
By the end of my second cycle, my estimated one-rep max had jumped 7.5 kg without ever touching a weight that made me question my form. That is the core promise of 5/3/1: slow, systematic, undeniable progress. This guide covers everything you need to run it properly.
What is the 5/3/1 program
5/3/1 is a strength training program created by Jim Wendler, a former competitive powerlifter and the author of 5/3/1: The Simplest and Most Effective Training System to Increase Raw Strength. It is built around four barbell lifts - squat, bench press, deadlift, and overhead press - with a simple wave-loading structure that cycles through different rep ranges every three weeks.
The name comes from the rep scheme across three weeks:
- Week 1: Sets of 5 at increasing percentages
- Week 2: Sets of 3 at higher percentages
- Week 3: A wave of 5, 3, then 1+ rep at the highest percentages
The "+" means AMRAP - as many reps as possible with good form. These AMRAP sets are where you prove your progress and push your limits within a controlled structure.
After every 3-week cycle, you increase your Training Max by a small, fixed amount and start the next cycle. The progression is slow by design. Wendler's philosophy is that starting too light and progressing too slowly are not real problems - starting too heavy and stalling is.
The philosophy behind 5/3/1
5/3/1 is built on four principles that separate it from most programs:
1. Start too light
Your working weights should feel manageable in week one. This is intentional. Starting light gives you room to build momentum, refine technique under load, and accumulate volume without grinding. Most lifters fail because they start too heavy, not because they start too light.
2. Progress slowly
Upper body Training Max increases by 2.5 kg (5 lbs) per cycle. Lower body increases by 5 kg (10 lbs). Over a year of consistent training, that is 30-40 kg on your squat and deadlift, 15-20 kg on your bench and overhead press. Those numbers are significant - but they only appear if you resist the urge to rush.
3. Set personal records
Every session contains one opportunity to set a rep PR on your top set (the AMRAP). This keeps training engaging even when the prescribed weights feel moderate. Hitting 85% for 8 reps when you could only manage 5 last cycle is a measurable win.
4. Balance strength with volume
5/3/1 is not just about the main lifts. Wendler prescribes assistance work - pulling, single-leg, core, and arm exercises - that builds the base your main lifts stand on. A bigger base supports bigger lifts long term.
How to set up your Training Max
The Training Max (TM) is the foundation of every 5/3/1 calculation. It is not your actual one-rep max. It is a conservative number you base all your percentages on.
Step 1: Find your current estimated 1RM
If you know your actual one-rep max, use it. If not, take a recent heavy set and estimate:
Estimated 1RM = Weight x (1 + Reps / 30)
Example: You squatted 100 kg for 8 reps. Estimated 1RM = 100 x (1 + 8/30) = 127 kg.
Step 2: Calculate your Training Max
Training Max = Estimated 1RM x 0.85 (beginners) or x 0.90 (experienced lifters)
Using the example above: TM = 127 x 0.85 = 108 kg (round to 107.5 kg).
If you are new to 5/3/1, use 85%. If you have run it before and know your recovery capacity, 90% is an option. When in doubt, go lower. The program adjusts itself over time.
Step 3: Calculate your working weights
All percentages are based on your Training Max, not your actual max. Here is the complete breakdown:
Week 1 (5/5/5+):
| Set | Percentage of TM | Example (TM = 107.5 kg) |
|---|---|---|
| Set 1 | 65% | 70 kg x 5 |
| Set 2 | 75% | 80 kg x 5 |
| Set 3 | 85% | 91 kg x 5+ (AMRAP) |
Week 2 (3/3/3+):
| Set | Percentage of TM | Example (TM = 107.5 kg) |
|---|---|---|
| Set 1 | 70% | 75 kg x 3 |
| Set 2 | 80% | 86 kg x 3 |
| Set 3 | 90% | 97 kg x 3+ (AMRAP) |
Week 3 (5/3/1+):
| Set | Percentage of TM | Example (TM = 107.5 kg) |
|---|---|---|
| Set 1 | 75% | 80 kg x 5 |
| Set 2 | 85% | 91 kg x 3 |
| Set 3 | 95% | 102 kg x 1+ (AMRAP) |
Round all weights to the nearest available increment (usually 2.5 kg for barbells).
5/3/1 Training Max calculator
Use this formula to calculate every weight you will use in your first cycle:
Your Training Max = (Your best set weight) x (1 + Reps / 30) x 0.85
Worked example for squat:
- Best recent set: 100 kg x 6 reps
- Estimated 1RM: 100 x (1 + 6/30) = 100 x 1.2 = 120 kg
- Training Max at 85%: 120 x 0.85 = 102 kg
Full cycle weights from a 102 kg Training Max:
| Week | Set 1 | Set 2 | Set 3 (AMRAP) |
|---|---|---|---|
| Week 1 (5s) | 65 kg (65%) x 5 | 77.5 kg (75%) x 5 | 87.5 kg (85%) x 5+ |
| Week 2 (3s) | 72.5 kg (70%) x 3 | 82.5 kg (80%) x 3 | 92.5 kg (90%) x 3+ |
| Week 3 (5/3/1) | 77.5 kg (75%) x 5 | 87.5 kg (85%) x 3 | 97.5 kg (95%) x 1+ |
Next cycle Training Max: 102 + 5 = 107 kg. Recalculate all percentages from the new TM.
Week-by-week breakdown: what a full cycle looks like
A standard 5/3/1 cycle is 3 weeks of training plus an optional 4th deload week. You train 4 days per week, one main lift per day.
Sample weekly schedule
| Day | Main lift | Assistance focus |
|---|---|---|
| Monday | Squat | Single-leg, core |
| Tuesday | Bench press | Push accessories, pull |
| Thursday | Deadlift | Posterior chain, core |
| Friday | Overhead press | Push accessories, pull |
Week 1: The 5s week
All three working sets are prescribed at 5 reps. The last set is 5+ (AMRAP). This week feels the lightest. Use it to dial in technique and build volume through higher AMRAP reps.
Week 2: The 3s week
Working sets drop to 3 reps with higher percentages. The last set is 3+. The intensity increases but the volume per set drops. AMRAP reps will be lower than week 1 - that is expected.
Week 3: The 5/3/1 week
The wave descends from 5 to 3 to 1+. The top set at 95% TM is the heaviest weight you touch in the cycle. This is where you find out what you are made of. Hit your rep target, then push for as many quality reps as you can.
The deload (every 2-3 cycles)
Wendler originally prescribed a deload every 4th week. Many lifters now deload every 7th week (two cycles on, one deload) or when performance signals fatigue. A deload week uses 40-60% of your TM for sets of 5 - enough to maintain movement patterns without accumulating fatigue.
After the cycle: increase the Training Max
- Upper body lifts (bench, OHP): add 2.5 kg (5 lbs)
- Lower body lifts (squat, deadlift): add 5 kg (10 lbs)
Recalculate all working weights from the new TM and start the next cycle. The jump is small. That is the point.
AMRAP sets: the engine of 5/3/1
The "+" sets are what make 5/3/1 more than a percentage calculator. Here is how to execute them properly.
How to approach AMRAP sets
Push for maximum reps with good form. Stop when your technique breaks down or you have 1 rep left in reserve. The goal is to accumulate volume at a meaningful intensity, not to grind out ugly reps.
Rules for AMRAP sets:
- Full range of motion on every rep
- Maintain consistent tempo - if the bar slows dramatically, consider stopping
- Never sacrifice form for one more rep
- Record the exact number of reps you completed
Why AMRAP reps matter for progression
Your AMRAP performance is the best indicator of whether your Training Max is set correctly. If you are hitting 5+ reps on your 1+ set in week 3, your TM is appropriate. If you can barely hit the prescribed reps, your TM is too high.
AMRAP benchmarks for the 1+ set (week 3, 95% TM):
| Reps hit | What it means |
|---|---|
| 1-2 | TM is too high - consider resetting |
| 3-5 | TM is appropriate - continue progressing |
| 6-8 | TM is conservative - keep going, progress is strong |
| 9+ | TM may be too low - but this is not a bad problem to have |
These AMRAP numbers also let you estimate your current 1RM without ever maxing out. If you hit 95 kg for 7 reps, your estimated 1RM is about 117 kg - and you have the data to prove it without the injury risk of testing. For more on how to use estimated maxes, see our progressive overload guide.
Assistance work: building the base
The main lifts get you strong. Assistance work keeps you balanced, healthy, and growing. Wendler organizes assistance into three categories:
Push
Anything that involves pressing or triceps extension. These support your bench press and overhead press.
Examples: Dumbbell bench press, incline press, dips, push-ups, triceps pushdown, overhead extension.
Volume: 25-50 total reps per session.
Pull
Anything that involves rowing, pulling, or biceps. These support your deadlift and balance your pressing volume.
Examples: Barbell row, dumbbell row, chin-up, pull-up, face pull, band pull-apart, curls.
Volume: 25-50 total reps per session. Wendler recommends pulling in every session - yes, even on squat day.
Single-leg / Core
Unilateral leg work and core stability. These support your squat and deadlift while addressing imbalances.
Examples: Bulgarian split squat, lunges, step-ups, leg curls, hanging leg raise, ab wheel, plank.
Volume: 25-50 total reps per session.
How to structure a full session
Here is what a complete squat day looks like in practice:
| Component | Exercise | Sets x Reps |
|---|---|---|
| Warm-up | Light squat ramp-up | 3-4 x 5 at 40-60% TM |
| Main work | Squat (5/3/1 sets) | 3 x prescribed (last set AMRAP) |
| Supplemental | Squat variation (see BBB/FSL below) | 5 x 5-10 |
| Assistance - Push | Dips | 3 x 10-15 |
| Assistance - Pull | Dumbbell row | 3 x 10-15 |
| Assistance - Legs/Core | Hanging leg raise | 3 x 10-15 |
Total session time: 60-75 minutes including warm-up.
5/3/1 variations: BBB and FSL
The base 5/3/1 structure stays the same across variations. What changes is the supplemental work - the sets you do after the main 5/3/1 lifts and before assistance.
Boring But Big (BBB)
After your main 5/3/1 sets, do 5 sets of 10 reps at 50-60% of your Training Max on the same exercise (or a close variation).
Example squat day:
- Main work: Squat 5/3/1 sets
- Supplemental: Squat 5 x 10 at 50% TM
BBB adds significant hypertrophy volume. It is challenging - 50 reps at moderate weight after heavy work is no joke. Start at 50% TM and increase to 60% over multiple cycles if recovery allows.
Best for: Lifters who want to build muscle mass alongside strength. The volume is high, so eating and sleeping enough matters.
First Set Last (FSL)
After your main 5/3/1 sets, do additional sets at the weight of your first working set for that day.
Example squat day (week 1):
- Main work: 65% x 5, 75% x 5, 85% x 5+
- Supplemental: 65% x 5 for 3-5 additional sets
FSL is lower stress than BBB. The weights are lighter, the sets are easier, and recovery is more manageable.
Best for: Beginners to 5/3/1, lifters in a calorie deficit, or anyone who finds BBB too taxing. FSL is also excellent for building technique under moderate fatigue.
Which variation to pick
| Factor | BBB | FSL |
|---|---|---|
| Volume | High (50 supplemental reps) | Moderate (15-25 supplemental reps) |
| Intensity | Moderate (50-60% TM) | Low-moderate (first set weight) |
| Recovery demand | High | Moderate |
| Hypertrophy | Excellent | Good |
| Best for | Mass building, eating at surplus | Skill building, cutting, beginners |
If this is your first time running 5/3/1, start with FSL. You can always switch to BBB in your third or fourth cycle once you understand the program's rhythm.
Common 5/3/1 mistakes
1. Setting the Training Max too high
The most common mistake. If you are using your actual 1RM as your TM, every percentage is inflated. Your AMRAP sets suffer, your form degrades, and you stall within two cycles. Use 85-90% of your 1RM as your TM. If you can not hit at least 3 clean reps on your 1+ set, your TM is too high.
2. Skipping the AMRAP
Some lifters treat the "+" sets as regular prescribed reps - hitting 5, 3, or 1 and racking the bar. The AMRAP is not optional. It is the primary driver of progress and the diagnostic tool that tells you if your TM is correct.
3. Ignoring assistance work
Running 5/3/1 with only the main lifts is like building a house on stilts. The main lifts develop peak strength, but assistance work builds the muscle mass, joint health, and structural balance that supports long-term progress. Do your pulls. Do your core work.
4. Increasing the TM too aggressively
Adding 5 kg to bench instead of 2.5 kg because "it was easy" breaks the program's logic. The small increments are calculated to sustain progress for years. Doubling the increase cuts the program's effective lifespan in half.
5. Changing the core structure
Adding extra main lift days, swapping percentages, or replacing the wave loading with linear progression turns the program into something that is not 5/3/1 and has not been tested. Run the program as designed for at least 3-4 cycles before considering modifications.
6. Not tracking AMRAP reps
Your AMRAP numbers are the most important data points in 5/3/1. Without them, you have no idea whether your TM is correct, whether you are progressing, or when to reset. Log every rep of every AMRAP set. A gym log app like Pully makes this painless.
When to reset your Training Max
Progress is not linear forever. After several cycles, your AMRAP performance will decline. When your 1+ set drops to 2-3 reps consistently, it is time to reset.
How to reset:
- Recalculate your estimated 1RM from a recent AMRAP performance
- Set your new TM at 85% of that estimate
- Start a fresh cycle
Resets are not failures. They are part of the program's design. You come back with better technique, more capacity, and room to push new AMRAP records.
Frequently asked questions about 5/3/1
How long does it take to see results from 5/3/1?
Most lifters see measurable strength gains within two full cycles (6 weeks). The first cycle often feels deceptively easy - that is normal. Your AMRAP numbers will tell the real story: if your rep count on the 1+ set improves each cycle, the program is working. Visible strength gains on your tested lifts typically appear by cycle 3-4 (9-12 weeks).
Is 5/3/1 good for beginners?
5/3/1 works for beginners who are comfortable with the four main barbell lifts (squat, bench, deadlift, overhead press) and have reasonable form. Complete beginners should learn the movements first - either with a coach or through a full-body plan - then transition to 5/3/1. The FSL variation is the best starting point.
How long does a 5/3/1 session take?
A typical session takes 60-75 minutes: 10-15 minutes of warm-up, 15-20 minutes of main 5/3/1 work, 15-20 minutes of supplemental work (BBB or FSL), and 15-20 minutes of assistance. If you superset your assistance exercises, you can trim the total to under 60 minutes.
Can I run 5/3/1 three days per week?
Yes. Combine two lifts into one day or rotate four lifts across three training days. A common 3-day setup: Monday squat + bench, Wednesday deadlift + OHP, Friday squat + bench (alternating each week). The progression remains the same.
How does 5/3/1 compare to PPL?
PPL organizes training by movement pattern with flexible exercise selection. 5/3/1 is a structured strength program built around four specific barbell lifts with prescribed percentages. PPL is better for general hypertrophy and bodybuilding-style training. 5/3/1 is better for systematic strength progression with less decision-making per session. Many lifters use PPL-style assistance work within a 5/3/1 framework.
What if I miss a workout?
Pick up where you left off. If you missed Wednesday's deadlift session, do it on your next training day and continue the cycle. Do not skip sessions to stay on schedule - every session matters. If you miss more than a week, consider restarting the current week rather than jumping ahead.
How to run 5/3/1 in Pully
5/3/1 has more structure than most plans - specific percentages, Training Max tracking, AMRAP logging, and cycle-over-cycle progression. Pully handles all of it.
Plan builder - set up your 4-day template: Squat day, Bench day, Deadlift day, OHP day. Each day includes the main lift, supplemental work, and your chosen assistance exercises.
Auto-fill from last session - when you open Bench day in week 2, your weights from last week's Bench day are already loaded. Your assistance exercise weights carry forward too. No manual lookups.
AMRAP tracking - log your exact rep count on every "+" set. Pully records it alongside the weight, giving you a running history of AMRAP performance across cycles.
Week-over-week comparison - see at a glance whether your AMRAP reps are improving. This is the core signal for progressive overload in 5/3/1.
Per-variant tracking - if your BBB sets use a squat variation (front squat instead of back squat), each variant maintains its own history. Your data stays clean across cycles.
Cycle history - review your Training Max progression and track your gym progress over months, not just sessions.
Download Pully from the App Store and set up your first 5/3/1 cycle before your next session.
Your 5/3/1 starter checklist
Step 1: Find your current estimated 1RM for squat, bench, deadlift, and overhead press. Use a recent heavy set if you do not have a tested max.
Step 2: Calculate your Training Max. Multiply your 1RM by 0.85 (beginners) or 0.90 (experienced).
Step 3: Pick a variation. FSL for your first cycle. Consider BBB after 2-3 successful cycles.
Step 4: Plan your assistance. 25-50 reps each of push, pull, and single-leg/core work per session.
Step 5: Run the cycle. Three weeks of 5/5/5+, 3/3/3+, 5/3/1+. Record every AMRAP rep.
Step 6: Increase the Training Max. Add 2.5 kg (upper body) or 5 kg (lower body). Start the next cycle.
Step 7: Deload when needed. Every 2-3 cycles, or when AMRAP performance declines across multiple sessions.
5/3/1 rewards patience. The weights will feel light at first. The increments will feel small. But after six months of consistent cycles, you will look back at your training log and see undeniable, measurable progress that no random plan could match. Trust the process, track the data, and let the AMRAP sets do the talking.
