Estimate your one-rep max from a recent set, then see how your strength compares to general population standards for your bodyweight — for squat, bench press, deadlift, and overhead press.

How to Use the Strength Calculator
- Select your lift (squat, bench press, deadlift, or overhead press).
- Select your sex and enter your bodyweight.
- Enter the weight you lifted and how many reps you completed with it.
- Click "Calculate Strength Level" to see your estimated one-rep max, bodyweight ratio, and general strength classification.
How This Is Calculated
Your one-rep max (1RM) is estimated using the Epley formula, one of the most widely used methods for predicting max strength from a submaximal set:
1RM = Weight Lifted × (1 + Reps ÷ 30)
Your 1RM is then divided by your bodyweight to get a ratio, which is compared against general population-based bodyweight-ratio benchmarks (novice, intermediate, advanced, elite) for your selected lift and sex.
Frequently Asked Questions
How accurate is the Epley formula?
It's a widely used estimate, most accurate for rep ranges under about 10. Very high rep sets (15+) tend to produce less reliable 1RM estimates.
Are these strength standards official?
No — they're general population-based reference ranges commonly used across fitness calculators, not an official governing body's standard. Individual results vary based on training history, limb length, technique, and other factors.
Should I actually attempt a true 1-rep max to test this?
Not necessarily, especially without a spotter or coach — using a formula-based estimate from a safer, lower-risk set is generally the recommended approach for most lifters rather than testing a true max frequently.
