5/3/1 Triumvirate: Wendler's Original Template, Explained

What is the 5/3/1 Triumvirate?

The Triumvirate comes from Jim Wendler's first 5/3/1 book, where it sits beside Boring But Big. The rule is strict: three exercises per training day and no more. The first is the day's main lift, run through the normal 5/3/1 progression. The other two are assistance exercises done for 5 sets each.

Where Boring But Big follows the main lift with fifty more reps of the same barbell lift, the Triumvirate follows it with two well-chosen assistance exercises. That means less volume and much easier recovery. What follows is the widely published base version, and Wendler's books have the full method.

The 4-day schedule

The Triumvirate uses the classic 5/3/1 split: four sessions per week with one main lift each, in the book's order of press, deadlift, bench and squat. Each session is the main lift plus its two assistance exercises:

• Day 1: Overhead press 5/3/1 sets, then dips 5x15 and chin-ups 5x10
• Day 2: Deadlift 5/3/1 sets, then good mornings 5x12 and hanging leg raises 5x15
• Day 3: Bench press 5/3/1 sets, then dumbbell bench press 5x15 and dumbbell rows 5x10
• Day 4: Squat 5/3/1 sets, then leg press 5x15 and leg curls 5x10

These are the pairings from Wendler's book example, and each pair is complementary. Press day gets a push and a pull. Deadlift day gets abs and more work for the posterior chain (hamstrings, glutes and lower back). Bench day adds pressing volume and upper-back work, and squat day adds quads and hamstrings.

They are a starting point, not scripture. The 5/3/1 assistance work article covers what each slot is for and how to substitute.

The main-lift percentages by week

The main work is identical to every other 5/3/1 variant. All percentages are of your Training Max (TM), which is 90% of your true or estimated 1RM and never your actual max:

The final set of weeks 1-3 is an AMRAP set: as many quality reps as possible, stopping 1-2 short of technical failure. Warm up with roughly 40, 50 and 60% of TM for 5, 5 and 3 reps. On the deload week you do the main lift only, with no AMRAP and no assistance. The full set-by-set breakdown is in 5/3/1 percentages by week.

The 5x15 / 5x10 assistance scheme

Each assistance exercise gets 5 sets, usually one exercise around 15 reps and one around 10. That is fifty to seventy-five reps per exercise at moderate loads. The point is added muscle and work capacity, not another maximal effort.

Pick weights you could do a few more reps with and rest about 90 seconds between sets. Progress by adding reps first and weight second. The heavy lifting for the day already happened in the main sets.

Progression cycle to cycle

After each 4-week cycle, add 5 lbs (2.5 kg) to your upper-body Training Maxes and 10 lbs (5 kg) to your lower-body ones, then run the next cycle. That pace looks slow, and it is the reason the program works for years. The AMRAP sets let you show extra strength right away while the TM climbs behind it.

If a lift stalls, with grinding AMRAP sets or missed reps, reset that TM to 90% of its current value and rebuild. First-cycle setup is covered in how to start the 5/3/1 program.

Is the 5/3/1 Triumvirate a beginner program?

It depends which beginner. If you are in your first months of lifting and still add weight to the bar every session, keep doing that. Hardy's 5/3/1 for Beginners routine is the better start if you want 5/3/1 from day one.

The Triumvirate suits the late beginner: weekly progress has stalled and the four main lifts are technically stable. One main lift and two assistance exercises per day is easy to learn. Set your first Training Max at 90% of an estimated 1RM from a recent hard set of 3-5 reps, and go lower when in doubt. How to calculate your Training Max has the method.

The book's assistance numbers assume some training history, so scale them:

• Chin-ups: 5 sets of as many clean reps as you have, or band assistance or lat pulldowns until 5x10 is realistic.
• Dips: bench dips, push-ups or assisted dips for 5x15.
• Good mornings: an empty or lightly loaded bar for the first cycles, or Romanian deadlifts or back raises instead.
• Hanging leg raises: bent-knee or lying leg raises for the same 5 sets.

Is the 5/3/1 Triumvirate enough volume?

For strength, yes. The main sets are the same progression engine as every other 5/3/1 variant, and the two assistance blocks add 100-135 quality reps per session. For maximum muscle growth, no: most muscle groups get around 10 hard sets per week, below what dedicated hypertrophy training uses. That is by design, because the Triumvirate trades volume for recovery and short sessions.

The AMRAP set is your volume meter. If those reps climb from cycle to cycle, the program has all the volume it needs. Do not judge it in your first two cycles, because the Training Max starts conservative and week 3 at 95% collects the debt.

If AMRAP reps stall while sleep and food are good, add volume in this order:

• Push the existing assistance: take every 5-set block to the top of its rep range, then add load.
• Add one assistance exercise per day for 25-50 easy reps, such as curls, face pulls, back raises or ab work.
• Switch a cycle to Boring But Big or First Set Last for structured barbell volume.
