The Conjugate Method — the Westside Barbell® system — has an intimidating reputation and a lot of jargon. It doesn't have to. Here's the plain-English version: the three methods, the weekly template, the signature lifts, and an honest look at who it's actually for.
The Conjugate Method is a strength system where, in the same week, you lift something near-maximal, lift something submaximal as fast as possible, and do higher-rep accessory work — while constantly rotating the main exercises so your body never fully adapts and stalls. It was popularized for powerlifting by Louie Simmons at Westside Barbell®, adapted from the Soviet "conjugate sequence system." Its three pillars are the Max Effort, Dynamic Effort and Repetition methods, run across a classic four-day week. It's a proven system for advanced strength, though whether it's the best choice for raw or beginner lifters is genuinely debated.
"Conjugate" simply means coupled in sequence — arranging training so several qualities are developed at once and each feeds the next, rather than training strength, then speed, then size in separate blocks. In practice, a Conjugate week hits maximal strength, explosive speed and muscle-building volume simultaneously, and swaps the main lifts often so you never plateau on any one of them. The system was made famous by Louie Simmons (1947–2022), the powerlifting coach behind Westside Barbell® in Columbus, Ohio, who spent roughly forty years refining it.
One point of accuracy that's often mangled online: Simmons did not invent the conjugate concept. The "conjugate sequence system" comes from Soviet sports scientist Dr. Yuri Verkhoshansky. Simmons found it in translated Soviet literature and adapted it for powerlifting — fusing it with dynamic-effort speed work and accommodating resistance (bands and chains) into what people now call the Westside method. Crediting Verkhoshansky isn't a footnote; it's the honest version of the story. Read the full profile of Louie Simmons →
Conjugate rests on three training methods, used every week. Get these and you understand the system.
| Method | What you do | What it builds |
|---|---|---|
| Max Effort (ME) | Work up to a near-1RM on a variation of the squat, deadlift or bench | Absolute strength — the ability to grind a heavy weight |
| Dynamic Effort (DE) | Lift ~50–60% at maximal speed, usually with bands or chains, for many short sets | Speed-strength — rate of force development, moving weight fast |
| Repetition (RE) | Higher-rep accessory work, often to or near failure | Muscle size, work capacity, and shoring up weak points |
Two ideas make it "conjugate." First, the max-effort lift rotates frequently — roughly weekly — so you don't accommodate to a single movement and stall; a given variation might only come back around every couple of months. Second, accommodating resistance: bands and chains add load as the bar rises, matching the strength curve and forcing you to keep accelerating. Dynamic-effort days classically run a three-week wave of about 50%, 55% and 60% bar weight plus roughly 25% accommodating resistance, then the movement swaps and the wave repeats.
The classic Westside week is four training days, splitting max-effort and dynamic-effort work for the lower and upper body so they don't collide. Days are typically spaced about 72 hours apart.
| Day | Focus | Example main work |
|---|---|---|
| 1 | Max Effort Lower | Work up to a heavy single on a squat or deadlift variation (e.g. box squat, good morning), then accessories |
| 2 | Max Effort Upper | Work up to a heavy single on a bench variation (e.g. floor press, board press), then triceps/back accessories |
| 3 | Dynamic Effort Lower | Speed box squats and speed pulls at 50–60% with bands/chains, then posterior-chain accessories |
| 4 | Dynamic Effort Upper | Speed bench at 50–60% with bands/chains, then triceps, delts and upper-back volume |
Conjugate has a recognizable toolbox of movements and machines. These are the ones most associated with it — each has its own full form guide:
Two of these — the reverse hyper and the belt squat machine — are credited to Louie Simmons himself, who patented the reverse hyper (patent issued 1994).
This is the most useful honest question about the system, and coaches genuinely disagree. Here are both sides.
The case for caution: Conjugate was built in a geared (multi-ply) powerlifting environment, where supportive suits and shirts change where the lift is hardest. Critics argue that the heavy band-and-chain lockout overload suits a geared lifter's sticking point (the top) more than a raw lifter's (often the bottom). They also note a specificity problem: if you box-squat and floor-press in training but must free-squat and pause-bench at a meet, you may under-practice the actual competition skill. And the high concurrent volume is easier to recover from with the assistance some elite lifters use.
The case for it working raw: plenty of respected coaches run modified Conjugate with raw and even novice lifters — rotating between competition-style and slightly-varied main lifts, dialing back the exotic bar setups, and keeping the core ME/DE/RE structure. Used that way, the constant variety keeps training fresh and addresses weak points well.
The balanced takeaway: Conjugate is a proven system for advanced strength, and it can work raw with sensible modifications — but it isn't the obvious first choice for a beginner. Most novices progress fastest on a simple linear program first (see Starting Strength or 5/3/1), then graduate to Conjugate once linear gains stall. Treat the critiques above as documented coaching-community positions, not settled science — the head-to-head research comparing training systems is thin.
Conjugate is unusually demanding to track — the main lift rotates weekly and you're logging both max-effort records and dynamic-effort percentages — which is exactly where a good logger earns its keep. Log any movement in LiftHero (free, unlimited) — this week's box squat max, your speed-bench percentages, the accessory volume — and it charts the trend and flags PRs so you can see whether the rotation is actually moving your numbers. Want the whole four-day split saved as a repeatable plan with your ME rotation mapped out? Build it as a custom program with Hero, LiftHero's optional upgrade. LiftHero records what you log; it doesn't auto-generate or auto-rotate the program for you.

The underlying conjugate sequence concept comes from Soviet sports scientist Dr. Yuri Verkhoshansky. Louie Simmons did not invent conjugate periodization; he adapted it for powerlifting over roughly four decades at Westside Barbell®, adding dynamic-effort speed work and accommodating resistance.

Max Effort (work up to a near-1RM on a variation to build absolute strength), Dynamic Effort (lift ~50–60% at maximal speed, usually with bands or chains, for speed-strength), and the Repetition Method (higher-rep accessory work for muscle, work capacity and weak points).
It's debated. The system grew up in a geared environment, and critics argue its lockout-overload bias and constant exercise rotation fit geared lifters and can under-practice the competition lifts. Many coaches run modified Conjugate raw successfully. Beginners usually progress fine on simpler linear programs first.
Four days: Max Effort Lower, Max Effort Upper, Dynamic Effort Lower and Dynamic Effort Upper, each followed by accessories and spaced roughly 72 hours apart so max-effort and speed work for the same lift don't collide.
Because the main lift rotates and you track both max-effort records and speed work, logging matters. LiftHero records any movement and its loads, so you can note this week's ME variation and your DE percentages and review the trend. It doesn't auto-generate the program.
