5/3/1 Triumvirate: The Original Assistance Template

The Triumvirate is one of the original assistance templates from Jim Wendler’s first 5/3/1 book, and it remains one of the cleanest. The name says it all: each training day is built around three movements — your main lift plus exactly two assistance exercises. No sprawling accessory circuits, no decision fatigue. Three things, done well.

What Is the Triumvirate?

After your main 5/3/1 working sets, the Triumvirate adds two assistance exercises, each for 5 sets, in a higher rep range. That’s the whole template. It’s designed for the lifter who wants more than the bare minimum but doesn’t want their session to balloon into an hour of accessories.

The two assistance moves on each day are chosen to support the main lift: one tends to drive the prime movers, the other balances the pattern (pulling against pressing, posterior chain against quads, midsection for the deadlift).

The Original Triumvirate Setup

As laid out in the original 5/3/1 book, the four days look like this:

Wendler presents these as a starting point, not a sacred list. If you don’t have a leg press, machine substitutions or front squats work. The structure — main lift plus two supporting movements for five sets each — is what matters, not the exact exercise.

Why Two Exercises Works

The Triumvirate solves a real problem with assistance work: most lifters do too much of it, poorly. Faced with an open-ended “do some accessories” instruction, people pile on a dozen half-hearted movements and call it volume.

Capping it at two exercises forces focus. You pick the two that matter for that lift, you do five hard sets of each, and you go home. It’s enough volume to drive growth and address weak points without compromising recovery for your main lifts — the thing that actually makes 5/3/1 work.

It also pairs naturally with the program’s philosophy of doing the minimum effective dose and progressing slowly.

Triumvirate vs. Other Templates

The Triumvirate sits in the middle of the assistance spectrum:

• Less than Boring But Big, which adds 5×10 of supplemental work on top of assistance
• More structured than “do 25–50 reps of push/pull/legs,” giving you named exercises and set counts
• Simpler than the periodized Leader/Anchor assistance schemes in 5/3/1 Forever

If you’ve run 5/3/1 for beginners and want a defined, no-nonsense assistance plan, the Triumvirate is a great next step. See how it compares to everything else in our guide to 5/3/1 templates.

Running the Triumvirate

The main work is the same percentages as any 5/3/1 cycle — use the 5/3/1 calculator to generate your working sets, then add the two assistance exercises for the day. Track them: five sets of fifteen on dips means little if you don’t know whether last week was bodyweight or weighted.

Train531 builds your main 5/3/1 work automatically and lets its AI coach prescribe and adjust your assistance based on your weak points and equipment — so if the textbook Triumvirate exercises don’t fit your gym, you get sensible substitutions instead of guessing. Whether you run the classic setup or a personalized version, the app keeps the volume honest and the progression on track.
