01
Unleash Wrist Wraps
Locks the wrist in a neutral position under load so the bar stays stacked over your forearm instead of flaring back.

02
Unleash Elbow Sleeves
Compression keeps the elbow and tricep tendon warm through heavy sets, which can reduce joint discomfort on a max attempt.

Unleash 7mm Leather Belt
A tight belt gives your torso something to brace against, raising intra-abdominal pressure for a more stable base to drive off.

This bench press calculator estimates your one-rep max (1RM) — the heaviest weight you could lift for a single clean rep — using the Epley formula. Enter the weight and reps from a recent working set to get your estimated max bench, a full training percentage chart for programming your next block, and a look at what's realistically on the table with the right gear under you.

Bench press calculator: frequently asked questions
What's my max bench press?
Your max bench press, or one-rep max (1RM), is the heaviest weight you can lift for a single rep with proper form. Testing it directly carries injury risk, so use a recent set of 2–8 reps in the calculator above — it estimates your 1RM using the Epley formula without you needing to attempt a true max.
How accurate is a bench press calculator?
Bench press calculators like this one are estimates, not exact measurements. They're generally accurate within a few percent for sets of 2–8 reps. Accuracy drops for very high-rep sets (12+) or sets taken close to failure, since fatigue affects the formula's assumptions. Treat the number as a training guide, not a competition entry.
How much should I be able to bench press?
There's no single answer — it depends on bodyweight, training age, and sex. What matters more is tracking your own number over time. Recalculate your estimated max every few weeks and use the percentage chart above to set your training weights for the next block.
How do I use the training percentages from this calculator?
Once you have your estimated max, the percentage chart shows the working weight for each intensity zone — typically 75–81% for volume work, 83–91% for strength work, and 94–100% for peaking. These are the same percentage ranges used in most powerlifting programming.
What can I do to increase my bench press max?
Progressive overload over time is the main driver of a bigger bench. Bar stability and joint comfort under heavy loads matter too, which is why lifters add wrist wraps, elbow sleeves, and a belt as their working weights climb — see the stack breakdown above for what each piece does. Curious whether a belt specifically is worth it for bench? We break that down here.
