What if you completed 405 lb for more than one rep?
A single is only one way to perform this weight. More completed reps raise the estimated one-rep max Endura scores, which can change the answer for your bodyweight. The examples below use the same model as the calculator; enter any whole-number rep count from 1 through 10 above for your exact result.
| Completed set | Estimated 1RM | Good for men at | Good for women at |
|---|---|---|---|
| 405 lb × 1 | 405 lb | 120–210 lb | Every row shown (100–220 lb) |
| 405 lb × 5 | 455.6 lb | 120–250 lb | Every row shown (100–220 lb) |
| 405 lb × 10 | 540 lb | Every row shown (120–260 lb) | Every row shown (100–220 lb) |
The men’s and women’s columns show the bodyweight ranges where each example reaches Intermediate or higher. If your bodyweight falls between rows, use the calculator result rather than rounding from the table.
