What Is 5/3/1?
5/3/1 is a strength training program created by powerlifter Jim Wendler. Originally published in 2009, it has become one of the most widely used and respected training programs in the strength community — and for good reason. It's built on simplicity, long-term progression, and a philosophy that prioritizes sustainable strength gains over quick, short-lived results.
The program is built around four core barbell movements: the squat, bench press, deadlift, and overhead press. Everything else is supplemental.
The Core Philosophy
Wendler's central belief: "Start too light, progress slowly, and break records." Most people fail in the long run because they start too heavy and stall out. 5/3/1 deliberately starts you conservatively so you can build momentum over months and years, not days.
How the Program Works
5/3/1 runs on a 4-week cycle. Each week, you work with a prescribed percentage of your Training Max (TM) — which is set at 90% of your actual one-rep max to start.
| Week | Sets × Reps | % of Training Max |
|---|---|---|
| Week 1 | 3 × 5 | 65%, 75%, 85% |
| Week 2 | 3 × 3 | 70%, 80%, 90% |
| Week 3 | 5/3/1 | 75%, 85%, 95% |
| Week 4 | Deload | 40%, 50%, 60% |
The final set of each day is an AMRAP (As Many Reps As Possible) set — you push beyond the prescribed reps. This is where real progress is measured and where personal records are broken.
The Weekly Training Split
The classic 4-day version looks like this:
- Day 1: Overhead Press + supplemental work
- Day 2: Deadlift + supplemental work
- Day 3: Bench Press + supplemental work
- Day 4: Squat + supplemental work
You can also run it as a 3-day program by combining or shifting days. Rest at least one day between sessions when possible.
Supplemental Work: The "Boring But Big" Template
The most popular supplemental approach is Boring But Big (BBB): after your main work sets, perform 5 sets of 10 reps at 50–60% of your Training Max for the same movement (or a related one). This builds size and work capacity on top of raw strength. It's unglamorous but extremely effective.
Progression: How You Get Stronger
At the end of each 4-week cycle, you increase your Training Max:
- Upper body lifts (press, bench): Add 2.5 kg
- Lower body lifts (squat, deadlift): Add 5 kg
These small jumps add up. After a year of consistent 5/3/1, you could be pressing 60+ kg more than when you started.
Who Is 5/3/1 For?
5/3/1 is best suited for intermediate lifters who have basic barbell technique and can no longer add weight every single session. Beginners may progress faster on a simpler linear program first. Advanced competitive powerlifters may need more specialized periodization. But for the vast majority of people who want to get seriously strong over the long term, 5/3/1 is an outstanding choice.
Final Word
The beauty of 5/3/1 is its simplicity and longevity. You're not chasing complexity — you're building a foundation of strength, one cycle at a time. Trust the process, hit your AMRAP sets with everything you have, and keep showing up. The iron will reward you.
