Estimating your bench press max

The bench press is the lift most lifters test and re-test, so it gets its own calculator here rather than sharing a generic page. Enter any recent working set — a set you took close to failure with good form — and this tool averages four standard 1RM formulas to estimate your true max.

Bench estimates from higher rep sets (10+) tend to run optimistic for lifters with less pressing endurance, and pessimistic for lifters who grind well. If your estimate looks off compared to how a max attempt has felt in the past, weight the lower end of the formula spread more heavily.

Use the plate calculator to figure out exactly which plates to load once you know your target working weight, or the kg to lbs converter if your numbers came from a metric program.

Where these numbers come from

The formulas and default values in this calculator are based on:

  • Epley (1985), Brzycki (1993), Lombardi (1989), and O'Conner et al. (1989) 1RM prediction formulas

These are planning estimates for training purposes. Check with a coach, trainer, or physician before starting a new program or maxing out.

Frequently asked questions

What's a good bench press for my bodyweight?

It depends heavily on bodyweight, sex, and training age. Check the strength standards calculator for a ratio-based comparison instead of a single universal number.

Why does my estimated max feel too high?

Formulas assume the set was taken close to true failure with strict form. A set left with 2 to 3 reps in the tank will overestimate your real max.

Should I use my flat, incline, or close-grip bench for this?

This calculator works for any bench variation, but the estimate only describes a max for that specific variation, not your flat bench max if you entered incline numbers.
