531 Lifting Calculator - Wendler 5/3/1 Working Weights

A 531 lifting calculator is a Wendler 5/3/1 program calculator that turns a single training max into the full 4-week percentage chart for squat, bench press, deadlift, or overhead press. The calculator applies the table from Beyond 5/3/1 (Week 1: 65/75/85 percent at 5/5/5+, Week 2: 70/80/90 percent at 3/3/3+ where set 3 is an AMRAP, Week 3: 75/85/95 percent at 5/3/1+, Week 4: 40/50/60 percent at 5/5/5) and rounds every working weight to the nearest 2.5 lb or 2.5 kg. Most lifters pair it with the One-Rep Max Calculator to derive a starting training max, then bump it by 5 lb for upper-body lifts and 10 lb for lower-body lifts.

• • Starting a new 5/3/1 cycle: enter 200 lb for bench press and the chart returns 130/150/170 lb in week 1, 140/160/180 lb in week 2, 150/170/190 lb in week 3, and an 80/100/120 lb deload in week 4.
• • Deriving a training max from a tested one-rep max: the true-max mode multiplies your tested max by 0.90.
• • Estimating from a submaximal set: the Epley mode takes a clean 3-rep or 5-rep weight and snaps the training max to the nearest 2.5 lb.
• • Running the cycle across all four lifts: repeat for squat, bench, deadlift, and overhead press in one cycle.

Most lifters pair this calculator with a one-rep max calculator to derive the training max from a tested one-rep max or an Epley submax estimate before running the program.

The calculator reads the lift, unit, and chosen max input, derives the training max if needed, snaps it to the nearest 2.5 (lb or kg), then multiplies by the Wendler percentage table for each week and set. The deload week (week 4) is built into the program and not optional, which is why it appears in the chart rather than folding into week 3.

• lift: the compound lift being programmed (squat, bench press, deadlift, or overhead press). The table is the same for all four.
• inputMode: direct training-max entry, true one-rep max (becomes trainingMax times 0.90), or submaximal weight and rep count (Epley to true max, then 0.90).
• trainingMax: the number Wendler programs against, set at 90 percent of the true max.
• trueMax: the tested one-rep max, used only in true-max mode. The calculator multiplies it by 0.90.
• submaxWeight and submaxReps: a clean submaximal weight and rep pair used only in submax mode. The Epley formula converts it into a true max estimate.
• unit: pounds (default) or kilograms. Rounding snaps to the smallest standard plate increment.

According to Jim Wendler, the training max controls program intensity, and 5/3/1 pairs each working week with an AMRAP top set (week 1 set 3 at 85% for 5+, week 2 set 3 at 90% for 3+, week 3 set 3 at 95% for 1+).

According to Wikipedia (One-repetition maximum), the Epley formula estimates one-rep max as weight times (1 plus reps divided by 30), with Boyd Epley's Poundage Chart (Body Enterprises, Lincoln, NE, 1985) as the original source.

A 5/3/1 cycle burns a steady number of calories across the four training weeks, and the calories burned weight lifting calculator estimates session energy so the lifter can keep calorie intake matched to the program load.

Four ideas explain every working weight the chart returns.

These four concepts cover every output in the chart. The training max anchors the percentages, the table defines the weekly shape of the program, the AMRAP sets produce strength progression, and the deload week protects the lifter from overtraining.

5/3/1 working weights only pay off if the lifter also eats enough to recover, and the macro calculator turns body weight and training intensity into a daily gram target that fuels a 5/3/1 cycle without body-fat drift.

Six short steps turn a single number into a loadable 4-week program.

1. 1 Pick the compound lift: squat, bench press, deadlift, or overhead press. The table is the same for all four.
2. 2 Pick the unit: pounds rounds to the nearest 2.5 lb; kilograms rounds to the nearest 2.5 kg.
3. 3 Choose how to enter your max: training-max, true-max, or submax mode.
4. 4 Enter the matching numbers: only the relevant pair is used; other fields can be left blank.
5. 5 Read the result panel: training max used, estimated true max, 12 weekly working weights, and warmup ladder.
6. 6 Repeat for the next lift or cycle: switch the lift selector, then bump the training max up by 5 lb (upper body) or 10 lb (lower body).

Practical example: a lifter enters a 200 lb bench press training max and reads off 130/150/170 lb for week 1, 140/160/180 lb for week 2, 150/170/190 lb for week 3, and an 80/100/120 lb deload for week 4. They load 130 lb for the first set of 5, 150 lb for the second, and 170 lb for the third set of 5 plus AMRAP reps.

A purpose-built 5/3/1 calculator removes the math and the plate-loading guesswork.

• • Full 4-week chart in seconds: one number returns all 12 working weights plus the top-set warmup.
• • Built-in deload week: week 4 is included so the lifter cannot skip the recovery week.
• • Epley submax mode: enter a clean 3-rep or 5-rep weight and the calculator estimates the true max.
• • True-max mode with auto training max: enter a tested one-rep max and the calculator multiplies by 0.90.
• • Loadable weights: every working weight snaps to the nearest 2.5 lb or 2.5 kg.

Recovery is the other half of any 5/3/1 cycle, and most lifters run the program alongside a daily protein target near 0.7 to 1.0 g per pound of body weight; the protein intake calculator converts body weight and training age into a daily gram target that lines up with Wendler's progression rule.

Three variables shape the chart, and two limitations tell you when to double-check.

• • The 5/3/1 percentage table is the Wendler default. Variations like BBB, FSL, and SSL add extra volume sets that this calculator does not generate.
• • The Epley submax mode is a single-set estimate. A tested one-rep max is always more accurate.

According to Jim Wendler, the 90 percent rule was the recommended starting point for a new 5/3/1 trainee, and the training max should be set conservatively so the lifter does not grind progress.

5/3/1 is a strength program, so the result panel does not track body composition directly, but most lifters check a baseline body fat percentage at the start of each cycle and after the deload to confirm the AMRAP sets add muscle without piling on fat.
