5/3/1 TRAINING MAX CALCULATOR

Calculate your Training Max — 90% of your 1RM — and instantly get all working weights for Jim Wendler's full 4-week 5/3/1 cycle for squat, bench press, deadlift, and OHP.

CALCULATE YOUR TRAINING MAX

Your Training Max will be 90% of this value.

WHAT IS THE 5/3/1 TRAINING MAX?

The Training Max is the cornerstone of Jim Wendler's 5/3/1 strength program. Rather than basing your working weights off your true one rep max, the program uses 90% of your 1RM as a submaximal starting point. This deliberate reduction builds in a safety margin, reduces cumulative joint stress, and ensures you can make consistent progress over months and years rather than burning out in weeks.

Wendler developed this approach after years of powerlifting and coaching. He noticed that lifters who always trained at their absolute limit plateaued quickly and were prone to injury. Using a conservative Training Max allows you to accumulate training volume at high quality and add small, sustainable weight each cycle.

HOW TO USE THIS CALCULATOR

Select your lift and unit system, then choose your input method. If you know your 1RM, select "Enter 1RM Directly" and type it in. The calculator will compute your Training Max by multiplying by 0.9 and rounding down to the nearest 5 lbs (or 2.5 kg).

If you don't have a tested 1RM, select "Calculate from Weight + Reps." Enter the weight and reps from a recent working set — ideally 3–6 reps performed close to failure. The calculator estimates your 1RM using the Epley formula, then derives your Training Max from that estimate. For best accuracy, avoid using sets of more than 10 reps.

After hitting "Calculate Training Max," you'll see your TM and a complete 4-week cycle table with exact working weights for every set — rounded to the nearest plate increment for practical use.

THE 4-WEEK 5/3/1 CYCLE EXPLAINED

Each training cycle lasts four weeks. The first three weeks progressively increase the top-set intensity while the rep target decreases. Week 4 is a planned deload that prepares your body for the next cycle.

Week 1 (5/5/5+): Three sets at 65%, 75%, and 85% of your Training Max. The last set is an AMRAP — go for as many clean reps as possible. Getting 5+ reps on the top set is a good sign; 8+ reps suggests your Training Max might be set too conservatively.

Week 2 (3/3/3+): Sets at 70%, 80%, and 90%. The top set intensity rises, so rep counts naturally decrease. The AMRAP is still there — push it.

Week 3 (5/3/1+): Your heaviest week: 75%, 85%, and 95% of TM. The top set at 95% is where many lifters hit PRs — especially early in the program when the Training Max is conservative.

Week 4 (Deload): Lower-intensity sets at 40%, 50%, and 60% of TM for 5 reps each. Do not skip this — it is programmed recovery, not optional.

After completing the 4-week cycle, increase your Training Max by 5 lbs for upper body lifts (bench, OHP) and 10 lbs for lower body lifts (squat, deadlift), then start the next cycle.

FREQUENTLY ASKED QUESTIONS

What is the 5/3/1 Training Max?
The Training Max (TM) is 90% of your actual one rep max. Jim Wendler designed the program around a submaximal training max rather than your true 1RM to provide a built-in safety margin, reduce joint stress, and allow for consistent progress over a longer period. All working weights in the program are calculated as a percentage of your Training Max, not your actual 1RM.
How do I calculate my Training Max?
Multiply your 1RM by 0.9, then round down to the nearest 5 lbs (or 2.5 kg). For example, if your squat 1RM is 315 lbs: 315 × 0.9 = 283.5, rounded down to 280 lbs. If you don't know your 1RM, use the 'Calculate from Weight + Reps' mode — enter a recent working set and the calculator will estimate your 1RM using the Epley formula first.
What are the percentages for each week of 5/3/1?
Week 1 (5/5/5+): 65%, 75%, 85% of TM. Week 2 (3/3/3+): 70%, 80%, 90% of TM. Week 3 (5/3/1+): 75%, 85%, 95% of TM. Week 4 (Deload): 40%, 50%, 60% of TM. The '+' on the last set means AMRAP — push for as many quality reps as possible.
How often should I increase my Training Max?
After each 4-week cycle, add 5 lbs (2.5 kg) to your upper body lifts (bench press, OHP) and 10 lbs (5 kg) to your lower body lifts (squat, deadlift). Wendler recommends keeping these increases small and conservative — the program is designed for long-term, consistent progress rather than maximal jumps.
What does the '+' mean on the last set?
The '+' indicates an AMRAP set — As Many Reps As Possible. On weeks 1, 2, and 3, the final working set is performed for as many quality reps as you can complete while maintaining good form. The number of reps you get on these sets is a key indicator of your progress and informs future training max decisions.
Should I skip the deload week?
No. The Week 4 deload is intentional and critical to the program's success. It allows your joints, tendons, and nervous system to recover before the next training cycle. Many lifters feel strong enough to skip deloads, but doing so over multiple cycles leads to accumulation of fatigue and eventual plateaus or injury. Treat the deload as part of the program, not optional.
Can I use this calculator for lifts other than the big four?
The 5/3/1 program is designed for the squat, bench press, deadlift, and overhead press. The math works for any barbell movement, but Wendler specifically programs these four lifts as the primary movements. If you use 5/3/1 percentages on accessory lifts, treat the results as a rough guide rather than exact programming.
What if I don't know my true 1RM?
Use the 'Calculate from Weight + Reps' mode. Enter a recent working set — ideally 3–6 reps performed close to failure. The calculator uses the Epley formula (weight × (1 + reps/30)) to estimate your 1RM, then calculates your Training Max from that estimate. Avoid using sets of more than 10 reps, as 1RM estimates become less accurate at higher rep ranges.
