Estimating your bench press max
The bench press is the most tested — and most asked about — max in the gym. Because bench uses less total muscle mass than squats or deadlifts, rep-based estimates track it well: a hard set of 2-6 reps predicts your single within a few percent for most lifters.
One thing to keep consistent: estimate from the same style you test with. Touch-and-go reps run heavier than paused reps, so if you care about a paused competition bench, estimate from paused sets. And an all-out set of 5 (RPE 10) at 100 kg predicts roughly a 115 kg single — which is why 225 lbs for a few reps means the 245-250 club, not just 225.
The math behind the estimate is explained on the 1RM calculator page, and the full RPE-to-percentage chart lives on the RPE calculator. The method works for every lift; this page pairs it with bench press-specific defaults and advice.
Put your bench press 1RM to work
A max estimate is only useful when a program turns it into working weights. These Hardy routines are built around percentage-based bench press progression:
- 5/3/1 Boring But Big — the classic strength + volume template, with bench twice a week
- nSuns 531 LP (4-day) — high-volume pressing built around rep-max progression
Running 5/3/1? Convert this estimate into a Training Max with the Training Max calculator, or generate the whole cycle with the 5/3/1 calculator.
Frequently asked questions
How do I calculate my 1 rep max bench press?
Take a recent hard bench set and note the weight, the reps, and how many reps you had left (RPE). The combination maps to a percentage of your 1RM: for example, 5 reps at RPE 10 is about 86% of your max, so benching 100 kg for an all-out set of 5 predicts roughly a 115 kg single.
Is 225 lbs a good bench press?
Two plates (225 lbs / 102 kg) is a well-known milestone that puts most male lifters in the intermediate-to-advanced range; it typically takes 1-3 years of consistent training. For women, a bodyweight bench is a comparable long-term milestone. What counts as "good" scales with bodyweight, so judge progress against your own history first.
Should I test my true bench press max?
Rarely, and only when fresh and with a spotter or safety arms. Estimating from rep sets gives you a number that is accurate enough to program with, without the injury risk and fatigue cost of maxing. Most programs only need the estimate — 5/3/1, for example, uses 90% of your max anyway.
Do touch-and-go and paused bench have different maxes?
Yes — most lifters pause-bench about 5% less than touch-and-go. Estimate from the style you plan to test: if you want a paused (competition-style) max, base the calculation on paused sets.
How often should my bench 1RM go up?
Beginners can add weight almost weekly; after that, expect your estimated bench 1RM to climb every few weeks on a structured program. Bench progresses in the smallest jumps of the main lifts — 2.5 kg / 5 lbs per cycle in 5/3/1 — so track the estimate over months, not sessions.

Hardy tracks your bench press 1RM automatically
Log your training in the Hardy app and it estimates a fresh bench press max from every hard set you record, calculates your working weights from it, and moves them up as you get stronger.
