How much weight you can lift for a single repetition of a specific exercise? Use the Max Lift Calculator to determine. Simply input weight lifted (lbs) and number of reps performed into the calculator, it will display estimated max lift of exercise (lbs).
This calculator assists you in calculating your onerep max (1RM) based on the weight lifted and the number of repetitions performed. It can also estimate the weight you can lift for a given number of repetitions.
How to Use the Calculator
 Select Basic or Advanced Calculator: Choose whether you want to use the basic or advanced calculator.
 Enter Values: Fill in the required values. For the basic calculator, enter the weight lifted and the number of repetitions. For the advanced calculator, enter the total weight lifted, total repetitions, and number of sets.
 Press Calculate: The calculator will use your input to estimate your onerep max.
 View Results: Check the estimated max lift displayed by the calculator.
Formula Used
The max lift is calculated as follows:
Here, 0.03 is the constant used to adjust for the number of repetitions performed.
Sample Calculations:

Example 1:
 Weight Lifted: 150 lbs
 Number of Reps: 5
 Estimated Max Lift:
$150 \times (1 + (5 \times 0.03)  0.03) = 150 \times 1.12 = 168 \text{ lbs}$
Example 2:
 Weight Lifted: 200 lbs
 Number of Reps: 3
 Estimated Max Lift:
$200 \times (1 + (3 \times 0.03)  0.03) = 200 \times 1.06 = 212 \text{ lbs}$
