RM Chart — Rep Max Percentage Table

An RM chart maps each rep count to an approximate percentage of your 1RM. Coaches and lifters use it to quickly translate a program that says "5×5 at 85%" into an actual weight on the bar.

The percentages below are averages derived from widely used formulas (Epley, Brzycki). Individual variation exists — some lifters are more fatigue-resistant — but the table is a reliable starting point for most trainees.

For a personalized version based on your actual performance, enter a set into the StrengthBase calculator and check the generated RM table.

How to Use

Find your target rep count in the chart (e.g., 5RM = 89%).
Multiply your known 1RM by that percentage to get the working weight.
Round to the nearest plate increment and load the bar.

Frequently Asked Questions

Are RM percentages the same for every lift?: They are close, but lifts with more muscle mass (like squats and deadlifts) sometimes allow slightly more reps at a given percentage than isolation movements.
Why does my real rep count differ from the chart?: Genetics, training history, and muscle-fiber composition all influence fatigue resistance. The chart is an average — your personal curve may shift a few percent.
Can I use this chart for programming?: Yes. Many programs prescribe loads as percentages of 1RM. Use this chart as a quick lookup or let StrengthBase compute exact weights for you.
What about reps above 12?: Percentage estimates become less reliable above 12 reps because cardiovascular endurance and technique breakdown play a larger role. Treat high-rep estimates as rough guides.
