What the One Rep Max Calculator does
Use the free One Rep Max Calculator to estimate your 1RM from a lift and reps, with a full percentage-of-max training table.
That is the whole scope of the page. It sits in Health & Fitness, the group for fitness, nutrition & wellbeing. The One Rep Max Calculator only does the job in that first sentence.
One Rep Max Calculator runs in your browser. The file or the figures stay on your device, and the free plan does not ask you to create an account.
When a One Rep Max Calculator is the right page
Use it when you want a personal estimate from the measurements you have today.
Open it when you need to estimate your 1RM from a lift and reps, with a full percentage-of-max training table. If you need a different output, pick the tool whose description names that output.
How to use the One Rep Max Calculator
Enter height, weight, age, or the other measures the form asks for, in the units printed on the label.
Run it once with the values you have. The result should line up with this promise: Estimate your 1RM from a lift and reps, with a full percentage-of-max training table. Change one field if you want a second case, and keep the other fields the same so you can see what moved.
How to read the result
Read the result next to the formula the page names. A different formula, or a clinician, can land on a different number.
Keep the units, the dates, and the file type that the form showed. A number from the One Rep Max Calculator is ready to copy only after you have checked it against the labels on this page.
What the One Rep Max Calculator leaves out
This is not a diagnosis, a diet, or a training plan. It does not know injuries, medicine, or lab results you did not type.
Anything the description does not mention is outside this tool. Use the result as the estimate or the file this page promised, then check the source that actually applies to your bank, school, client, or project.
The next tool
