Jim Wendler's 5/3/1 Triumvirate: the classic 4-day strength program built on squat, bench press, deadlift and overhead press over a 4-week cycle. Three working weeks plus a deload, with every set calculated from your training max by Hardy automatically.
Each workout is one main lift at training-max (TM) percentages with an AMRAP final set, followed by exactly two assistance exercises — three lifts per day, the “triumvirate” that gives the template its name:
Main lift percentages:
Your training max is 90% of your 1RM. After each completed cycle, add 2.5 kg to the upper-body training maxes and 5 kg to the lower-body ones — slow, sustainable strength progression.
Warm up to the first work set (for example 40 / 50 / 60% of TM for 5 / 5 / 3 reps), and follow Wendler's advice to add conditioning work 2–3 times per week alongside the lifting.
Starting TM is 90% of 1RM.
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.
Double Progression: Work within 12-15 reps, adding one rep per successful session. At the top of the range, weight increases by 5 lbs; failing at the bottom decreases it by 5 lbs.
Double Progression: Work within 8-12 reps, adding one rep per successful session. At the top of the range, weight increases by 5 lbs; failing at the bottom decreases it by 5 lbs.
Double Progression: Work within 10-12 reps, adding one rep per successful session. At the top of the range, weight increases by 5 lbs; failing at the bottom decreases it by 5 lbs.
Double Progression: Work within 12-15 reps, adding one rep per successful session. At the top of the range, weight increases by 6 lbs; failing at the bottom decreases it by 6 lbs.

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.
The pairings above are a starting point, not scripture. The 5/3/1 assistance work article covers what each slot is for and how to substitute. The full set-by-set breakdown of the main lifts is in 5/3/1 percentages by week.
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:
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:
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.
A triumvirate is a ruling group of three. Each training day has exactly three exercises: the main 5/3/1 lift plus two assistance exercises. The name is the program's rule.
The main lift gets three work sets on the 5/3/1 waves, with the last set an AMRAP in weeks 1-3. Assistance is two exercises for 5 sets each, usually one around 15 reps and one around 10-12.
Not in your first two cycles. After that, add one assistance exercise per day only if AMRAP reps have stalled while sleep and food are good. Do not bolt a bodybuilding session onto it, because that is how the 95% week starts missing reps.
Yes. Like any 5/3/1 variant, you can rotate the four main-lift days across three weekly sessions, so a cycle takes longer than four calendar weeks. The 4-day layout is the classic version and the one to use if your schedule allows.
Both, in moderation. The main sets drive strength, and the 5x15 and 5x10 assistance blocks are straightforward hypertrophy work. If size is the primary goal, Boring But Big is the bigger stimulus: see 5/3/1 Triumvirate vs BBB.
