Wendler 5/3/1 Formula
Jim Wendler's 5/3/1 program uses a Training Max (TM) set at 90% of true 1RM as the program anchor. Four-week cycle: Week 1 sets at 65/75/85% TM × 5/5/5+ reps; Week 2 at 70/80/90% × 3/3/3+; Week 3 at 75/85/95% × 5/3/1+; Week 4 deload at 40/50/60%. After each cycle, add 5 lb to upper-body TMs and 10 lb to lower-body TMs. Sub-maximal weights enable long-term progression without burnout.
Formula
Copy the exact expression or work through it step by step below.
training_max = 0.90 × true_1rm
week_1: 0.65 × TM × 5, 0.75 × TM × 5, 0.85 × TM × 5+
week_2: 0.70 × TM × 3, 0.80 × TM × 3, 0.90 × TM × 3+
week_3: 0.75 × TM × 5, 0.85 × TM × 3, 0.95 × TM × 1+
week_4_deload: 0.40 × TM × 5, 0.50 × TM × 5, 0.60 × TM × 5
increment_per_cycle: +5 lb upper (bench, press), +10 lb lower (squat, deadlift) Variables
training_max
Training Max (TM)
90% of true 1RM. The conservative anchor that makes the program sustainable. Resist the urge to use full 1RM — the entire program's logic depends on the 10% buffer.
true_1rm
Real one-rep max
Recent tested or accurately estimated 1RM. Use a calculator (Epley/Brzycki) from a recent 3-5 rep max if not tested directly. Re-evaluate every 2-3 cycles if you suspect the TM is now off.
week_N
Week-specific working percentages
Each week has its own loading: Week 1 (5s), Week 2 (3s), Week 3 (5/3/1), Week 4 (deload). The '+' on the last set means AMRAP (as many reps as possible) — used to gauge progression.
increment_per_cycle
Cycle-to-cycle TM bump
Upper-body lifts (bench, overhead press) grow slower than lower-body (squat, deadlift) — biology, not philosophy. +5 lb / +10 lb is the canonical increment; can halve if AMRAP reps decline cycle-over-cycle.
Step By Step
- 1
Determine your 1RM for each of the four lifts (squat, bench, deadlift, overhead press).
Squat 1RM = 405 lb, Bench 1RM = 245 lb, Deadlift 1RM = 495 lb, OHP 1RM = 165 lb.
- 2
Compute Training Max = 0.90 × 1RM. Round down to nearest 5 lb (or 2.5 kg) for clean plates.
Squat TM = 365 lb, Bench TM = 220 lb, Deadlift TM = 445 lb, OHP TM = 150 lb.
- 3
Use weekly percentages × TM for prescribed sets.
Squat Week 1: 0.65 × 365 = 237.5 → 235 lb × 5, 0.75 × 365 = 274 → 275 × 5, 0.85 × 365 = 310 → 310 × 5+ (push for AMRAP on last set).
- 4
After 4-week cycle: add 5 lb to upper TMs, 10 lb to lower TMs.
Cycle 2: Squat TM 375, Bench TM 225, Deadlift TM 455, OHP TM 155.
- 5
Track AMRAP rep counts on last sets. If reps stagnate or drop across cycles, hold TM (no increment) or back off 10%.
Cycle 1 Squat 5+ at 310 lb hit 8 reps. Cycle 2 at 320 lb hits 7 reps. Cycle 3 at 330 lb hits 4 reps. Stop adding load; reset TM to 0.85 × current AMRAP-derived estimate.
Worked Example
Lifter starting Cycle 1 with Squat 1RM = 405 lb
True 1RM
405 lb
Training Max
0.90 × 405 = 365 lb
Week 1 (5s): 235 lb × 5, 275 lb × 5, 310 lb × 5+ Week 2 (3s): 255 lb × 3, 290 lb × 3, 330 lb × 3+ Week 3 (5/3/1): 275 lb × 5, 310 lb × 3, 345 lb × 1+ Week 4 (deload): 145 lb × 5, 185 lb × 5, 220 lb × 5
First cycle: top sets get harder but never grind to true max. After cycle, TM bumps to 375 lb (+10 lb lower-body increment). Year-over-year progress assuming consistent AMRAP improvement: ~50-100 lb on squat/deadlift, 20-40 lb on bench/press. Slower than novice linear progression — by design. Sustainable for years.
