Jim Wendler's 5/3/1

Jim Wendler published 5/3/1 after his own competitive powerlifting career, aiming for something a lifter could run for years, not just months. Where a beginner program pushes you to add weight every single session, 5/3/1 accepts that intermediates can't do that anymore and instead builds slow, deliberately conservative progress around a number called your Training Max (TM) — roughly 90% of your true one-rep max. Training slightly below your real max, and always leaving a rep or two in the tank on your work sets, is the whole philosophy: undershoot on paper so you can consistently hit your numbers in the gym.

The program runs one main lift per day across a four-day split: Squat Day, Bench Day, Deadlift Day, and OHP Day. Each session opens with a short warm-up specific to that lift — empty-bar squats plus light and medium warm-up sets at roughly 40% and 50% before squatting, an empty-bar set before bench, a hip-hinge drill before deadlifting, and shoulder circles before pressing — then moves into the main lift for three work sets, and finishes with two accessory exercises: Romanian Deadlift and Leg Press on Squat Day, Dumbbell Row and Tricep Pushdown on Bench Day, Leg Curl and Abs Work on Deadlift Day, and Chin-ups and Face Pulls on OHP Day.

The main-lift work follows a three-week percentage wave off your Training Max, and the workouts in this catalog show Week 1: 5 reps at 65% TM, 5 reps at 75% TM, then a final AMRAP set at 85% TM where you push for as many clean reps as you can past 5 — that's the "5/5/5+" pattern. Worked example: if your squat TM is 120kg, Week 1 looks like 5 reps at 78kg, 5 reps at 90kg, then an AMRAP set at 102kg where you might grind out 7 or 8 reps instead of stopping at 5. Week 2 tightens the reps and raises the percentages to 3/3/3+ at roughly 70/80/90% TM, and Week 3 tightens further to 5/3/1+ at roughly 75/85/95% TM — so by Week 3 your squat AMRAP set is a heavy single-digit-rep top set at around 114kg. Week 4 is a deload: light sets around 40/50/60% TM with no AMRAP, letting you recover fully before the next cycle. This app's workout catalog encodes the Week 1 percentages and rep targets for each lift; you apply the same 3/3/3+ and 5/3/1+ percentage adjustments yourself in Weeks 2 and 3, then drop to deload percentages in Week 4.

Progression happens once per four-week cycle, not once per session or even once per week. After you complete the deload week, you increase your Training Max — the classic rule is +2.5kg (or 5lb) on the upper-body lifts (Bench, OHP) and +5kg (or 10lb) on the lower-body lifts (Squat, Deadlift) — and then start the next cycle's Week 1 off the new, slightly higher TM. That's the entire progression model: small, fixed, almost boringly conservative jumps every month, rather than trying to set a new PR every week.

Deloads are built into the structure itself, not something you improvise when you feel beat up. Week 4 happens on schedule every single cycle regardless of how strong or fresh you feel, which is precisely what lets you keep adding to your TM indefinitely without digging a fatigue hole. Skipping the deload because "you feel fine" is one of the fastest ways to stall this program.

Common mistakes: setting your Training Max too high by using your true 1RM instead of 90% of it, which makes every week feel like a grind instead of leaving room for the AMRAP sets to actually be productive; treating the AMRAP set as optional and stopping at the prescribed rep count instead of pushing for extra reps, which is where most of the program's actual progress comes from; skipping the Week 4 deload; and neglecting accessory volume, since the main lift work alone on this program is intentionally light relative to what intermediates need for hypertrophy and general work capacity.

Expect a much slower, flatter progress curve than beginner linear progression — you're adding a total of maybe 10kg to your squat and deadlift TM and 5kg to bench and press TM every four to six weeks, not every workout. The payoff is that this pace is genuinely sustainable for years: lifters commonly run 5/3/1 for a full year or more, cycling through TM increases, occasional plateau-busting variations (5's Pro, First Set Last, different assistance templates), and periodic resets, and still be making real, if slow, progress at the end of it.
