5/3/1
5/3/1 is a percentage-based barbell strength program built around four main lifts — squat, bench press, overhead press, and deadlift — each trained once per week. The central philosophy is deliberate underloading: all working percentages are calculated from a training max (TM) set to roughly 90% of true 1RM, keeping most sessions comfortably below the athlete's actual limit. Progress is slow by design — small, reliable monthly increases compound into large long-term gains without the burnout and stalls that come from chasing true maxes every week.
How the Training Max Works
The training max is not your 1RM. Set it to approximately 90% of your current true 1RM, or — if you are new to the program — use a conservative estimate (a weight you could lift for 3–5 reps with technique intact). All week-by-week percentages in the program are calculated from this TM, not your true 1RM. This means working sets feel moderate early in a cycle, which is intentional. The cumulative fatigue over weeks 1–3 is what drives adaptation; no single session should feel like a true max effort until the AMRAP set on week 3.
The Four-Week Wave
Each lift runs through the same 4-week wave. Percentages are of the training max:
| Week | Set 1 | Set 2 | Set 3 |
|---|---|---|---|
| 1 | 65% × 5 | 75% × 5 | 85% × 5+ |
| 2 | 70% × 3 | 80% × 3 | 90% × 3+ |
| 3 | 75% × 5 | 85% × 3 | 95% × 1+ |
| 4 (deload) | 40% × 5 | 50% × 5 | 60% × 5 |
The + notation on the final set means AMRAP (as many reps as possible). Do not sandbag the AMRAP — it is the primary progress signal and auto-regulation mechanism of the program.
AMRAP Sets
The AMRAP set on weeks 1–3 serves two purposes. First, it creates overload beyond what the prescribed rep target alone would provide — if you're capable of 12 reps at 85% TM (week 1), you should do 12. Second, the rep count becomes a real-time e1RM estimate: a high AMRAP indicates the TM is conservative and monthly increases are sustainable; a barely-made AMRAP suggests you are near the TM ceiling and a reset may be approaching.
Do not end the AMRAP at a fixed number to "save something." Leave nothing on the bar (while maintaining form).
Progression
After completing each 4-week cycle, increase the training max:
- Upper body lifts (bench press, overhead press): +2.5 kg
- Lower body lifts (squat, deadlift): +5 kg
These increases are applied to the TM, not the true 1RM. Repeat the wave with the new TM.
When to reset: If AMRAP reps on the final set stall or decline across two consecutive cycles for the same lift, do not keep adding weight. Reset that lift's TM to 85–90% of the current TM and rebuild from there. Resets are not failures — they are mandatory maintenance that keeps the program running for years.
Assistance Work
The four main-lift sets are the core of each session. Wendler prescribes assistance templates to build muscle and address weaknesses around the main lifts. The most common is Boring But Big (BBB): after the main lift sets, perform 5 × 10 of the same lift (or a variation) at 50–60% TM. This adds significant volume without compromising recovery for the main sets.
Other common templates:
- First Set Last (FSL): After the main wave, do multiple sets at the first-set percentage (e.g., 65% on week 1). Less volume than BBB, better for busier schedules.
- Triumvirate: Three assistance exercises per session — one push, one pull, one single-leg/core — for 3–5 sets each.
Assistance work is not optional, but it is secondary. If recovery is compromised, cut assistance first, never main lift volume.
Why It Works
The submaximal training max ensures that the vast majority of sessions stay well clear of true failure. This limits accumulated fatigue, keeps technique cleaner under load, and makes the small monthly increases sustainable for years rather than weeks. Most lifters on aggressive linear progression stall within 3–6 months; 5/3/1 athletes regularly run productive cycles for 2–3 years before needing a major programming change.
The AMRAP set provides the intensity stimulus that simple submaximal training would lack, and the deload week provides the fatigue dissipation that allows the next cycle to start fresh. The result is a low-complexity, high-durability system that produces consistent strength gains without daily decision-making.
