216 lb works out to 1x45 + 1x35 + 1x5 per side plus the bar — call it 215 lb in practice, since gyms rarely stock the odd change. 5 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 185 lb set represents about 86% of the estimated max.
How far 216 lb can be trusted
Five reps is the most common way people estimate a max and the rep count these equations were checked against most often. The seven put your max between 208 and 220 lb. A set of five is short enough that breathing and pacing do not dominate it, so what the bar does on the fifth rep is a fair proxy for what it would do on a single — which is the assumption the whole method rests on.
Training loads from a 216 lb max
Programmes are written as percentages of the max, not as absolute weights. From 216 lb, rounded to the nearest 5 lb:
| Percentage | Load | Typical set |
|---|---|---|
| 95% | 205 lb | Heavy single |
| 90% | 195 lb | Doubles and triples |
| 85% | 185 lb | Sets of four to five |
| 80% | 175 lb | Sets of six |
| 75% | 160 lb | Sets of eight |
| 70% | 150 lb | Volume work, ten or more |
216 lb loads as 1x45 + 1x35 + 1x5 per side plus the bar, or 215 lb on the bar. Round every figure in that table to the nearest 5 lb and stop there — the seven formulas disagree by 12 lb on this set, so chasing a two-pound difference is chasing noise. If your gym stocks 2.5 lb pairs, save them for the top two rows, where a small miss costs the most reps.
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 185 lb for 5 reps; the headline figure is their median. All seven assume a set taken close to failure with clean technique. At 5 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 216 lb. This is a training estimate, not medical advice.
