In 1974, Soviet sports scientist A.S. Prilepin published research on optimal training loads for weightlifters. What he found became the volume prescription for the entire Westside Barbell system — and Conjugate Hybrid Training inherits it directly.
In 1974, Soviet sports scientist A.S. Prilepin published research on optimal training loads for weightlifters, analyzing data from hundreds of elite lifters to determine the relationship between training intensity and optimal lifting volume. His findings were organized into what became known as Prilepin’s Table. It is one of the most practically useful documents in strength training, and Louie Simmons built the volume prescription for the entire Westside Barbell system around it. Conjugate Hybrid Training inherits this prescription.
| Intensity Zone | Reps per Set | Optimal Total Lifts | Range |
|---|---|---|---|
| 55–65% | 3–6 | 24 | 18–30 |
| 70–75% | 3–6 | 18 | 12–24 |
| 80–85% | 2–4 | 15 | 10–20 |
| Above 90% | 1–2 | 7 | 4–10 |
The table tells you how many quality lifts the nervous system can handle in a single session at a given intensity before the training effect deteriorates. Go too far below the optimal range and the training stimulus is insufficient. Go too far above it and you accumulate fatigue faster than adaptation, bar speed drops, and quality degrades even if quantity remains high.
Simmons’ prescription for DE squats is 10–12 sets of 2 reps at 50–60% — 20–24 total lifts. This falls exactly in the optimal range for the 55–65% zone. DE bench is 8–10 sets of 3 reps at 45–60% — 24–30 total lifts, again in the optimal range.
Conjugate Hybrid Training honors this prescription. DE squat work: 8–12 sets of 2 reps depending on the wave and whether bands or chains are used. DE bench / push press: 8–9 sets of 3 reps. The variation in set count across waves isn’t arbitrary — it reflects the change in accommodation resistance. When significant band tension is added, fewer sets are needed because the total loading is higher.
Prilepin’s optimal for above 90% is 7 lifts, range 4–10. Simmons interprets this practically: one lift at approximately 90%, then a PR attempt, possibly one more. Total top-end lifts: 2–3 singles. Back-off sets drop into the 80% zone where Prilepin allows slightly more volume.
This is why ME days in the program prescribe: work up to a top set (RPE 8–9), then 2–3 back-off sets at 75–80% of the top. The back-off volume accumulates meaningful tension; the top set delivers the maximal neurological demand.
Simmons is explicit: true 1-rep maxes test strength, they don’t build it. A lift that takes you to genuine 100% effort every session is neurologically expensive, increases injury risk, and prevents accurate progress tracking because fatigue on any given day can mask actual capacity.
The Westside approach is daily maxes on special exercises, not competition lifts. Conjugate Hybrid Training applies the same logic. ME top sets are prescribed at RPE 8–9 — one or two reps clearly in reserve, technically sound, close to maximal but not grinding. These are logged as baselines for the next wave. Wave-over-wave progress is the benchmark, not in-session maximal effort for its own sake.
The first week of each new wave prescribes RPE 8 rather than 9. The ME variation is new, the nervous system is reorienting to a different movement pattern, and the appropriate stimulus is slightly submaximal relative to the wave peak. The first week establishes a baseline; the second week applies pressure; the third week expresses the wave peak. The deload resets the cycle.
Simmons uses an elegant calculation to keep bar volume constant across the wave despite changing percentages. For a 700-pound squatter:
50% of 700 = 350 × 12 sets × 2 reps = 8,400 lbs.
60% of 700 = 420 × 10 sets × 2 reps = 8,400 lbs.
The volume in pounds stays constant; the percentage and set count adjust to stay within Prilepin’s optimal range for each intensity zone. This prevents the common mistake of increasing both intensity and volume simultaneously — a recipe for accumulated fatigue and CNS burnout.
Doing too many heavy lifts produces CNS fatigue that accumulates faster than it can be recovered from. Progress stalls, form breaks down, bar speed drops on DE days, and the athlete often interprets this as needing to work harder, not less. The actual solution is reducing the number of high-percentage lifts and restoring the proper ratio between quality lifts and junk volume.
Staying at percentages lower than Prilepin’s optimal means insufficient stimulus. The nervous system isn’t being asked to do anything it can’t already do. Adaptation doesn’t happen. The athlete feels fine but isn’t getting stronger.
Prilepin’s Table is the math that keeps the program in the productive zone between these two failure modes — enough stimulus to force adaptation, not so much that fatigue outpaces recovery.
