Input: Input set: 315 lb x 5 reps
Calculation: Using Brzycki: 315 / (1.0278 - 0.0278 x 5) = 353.9
Result: Estimated deadlift 1RM: 354 lb
Deadlift estimates usually hold up best when the set is heavy but not grindy, which is why many lifters use a clean set of 3-5 reps.
Deadlifts accumulate grip fatigue and lower back fatigue faster than most lifts. By the time you reach 8-10+ reps, form breakdown and grip failure can cut a set short before the muscles are truly exhausted, which causes the calculator to underestimate your real max.
For calculator input, use whatever setup matches how you normally train. If you always pull with a belt, use belted numbers. The calculator estimates your max under the same conditions as the input set. Just be consistent so you can track progress over time.
Deadlift strength varies by bodyweight, age, sex, and training history. As a rough guide, an intermediate male lifter might deadlift around 1.5-2x bodyweight. Use the strength level ratings on this page or check the full deadlift strength standards for a detailed comparison.
