Estimate your lift 1RM from a recent set.

Estimate your one-rep max (1RM) using our calculator. Input the weight you lifted and the number of repetitions you completed for any given exercise. This tool provides an estimate of the maximum weight you could theoretically lift for a single repetition, offering a benchmark of your current strength for that movement.
Your 1RM is a critical metric for strength training. It helps you understand your current capabilities and provides a basis for setting effective training percentages. For example, if your 1RM for a squat is 100kg, you might train at 70-80% of that for hypertrophy or 85-95% for strength, depending on your program.
Use your estimated 1RM to strategically plan your workouts. Set appropriate weights for your working sets to ensure progressive overload, prevent overtraining, and maximize your results. Regularly re-test your 1RM (safely) or use this calculator to track your strength gains over time.

Your one-rep max is the maximum amount of weight you can lift for a single, complete repetition of a given exercise. It's a measure of your absolute strength for that specific movement.
This calculator provides an estimate based on established formulas. Its accuracy depends on your lifting technique and effort during the input set. For a precise 1RM, a spotter-assisted, controlled 1RM test is recommended.
Knowing your 1RM allows you to intelligently structure your training. You can use it to calculate working percentages for different rep ranges and training goals, ensuring you lift effectively for strength, hypertrophy, or endurance.
Re-testing your 1RM depends on your training phase and goals. For most lifters, re-testing every 8-12 weeks is sufficient to track progress without risking overtraining or injury. This calculator offers a safer way to estimate between live tests.
