461 lb works out to 4x45 + 1x25 + 1x5 per side plus the bar — call it 465 lb in practice, since gyms rarely stock the odd change. 6 reps sits comfortably inside the 2-to-10 range these formulas were fitted on, so this estimate is about as reliable as the method gets. Your 385 lb set represents about 84% of the estimated max.
How far 461 lb can be trusted
Six reps is where the equations start to separate. The 25 lb between 443 and 468 lb is wider than the same lifter would see from a triple, because past five reps the different curve shapes behind each formula begin to matter. Conditioning also starts to leak into the answer: a six-rep set asks something of your work capacity that a single does not, and lifters who are strong but poorly conditioned come out under-estimated here.
Training loads from a 461 lb max
Programmes are written as percentages of the max, not as absolute weights. From 461 lb, rounded to the nearest 5 lb:
| Percentage | Load | Typical set |
|---|---|---|
| 95% | 440 lb | Heavy single |
| 90% | 415 lb | Doubles and triples |
| 85% | 390 lb | Sets of four to five |
| 80% | 370 lb | Sets of six |
| 75% | 345 lb | Sets of eight |
| 70% | 325 lb | Volume work, ten or more |
461 lb is 4x45 + 1x25 + 1x5 per side plus the bar, 465 lb loaded. At this load the 25 lb the formulas disagree by is bigger than a pair of 10s, which is a good argument for programming off the lower estimate — 443 lb — and letting the bar prove you wrong rather than the other way round. Warm-up jumps also get long here; work up in percentages rather than in fixed plate increments.
The formulas behind this answer, and their limitations
The table above the fold is Epley (1985), Brzycki (1993), Lombardi (1989), O'Conner (1989), Wathan (1994), Lander (1985) and Mayhew (1992), each applied to 385 lb for 6 reps; the headline figure is their median. All seven assume a set taken close to failure with clean technique. At 6 reps you are still inside the fitted band, but conditioning is now affecting the result alongside strength, and the seven have begun to curve away from each other. They also under-rate strong, experienced lifters, who hold a higher percentage of max at any rep count than the regression average. The full account — the populations behind each equation, what a bounced rep does to it, and why we stop at ten reps — is set out on the methodology page. Warm up thoroughly and use safety bars or a spotter before going anywhere near 461 lb. This is a training estimate, not medical advice.
