How Does This Calculator Help You?

This calculator assists you in calculating your one-rep 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 one-rep max.
  • View Results: Check the estimated max lift displayed by the calculator.

Formula Used

The max lift is calculated as follows:

Max Lift=Weight Lifted×(1+(Reps Performed×0.03)0.03)\text{Max Lift} = \text{Weight Lifted} \times (1 + (\text{Reps Performed} \times 0.03) – 0.03)

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×(1+(5×0.03)0.03)=150×1.12=168 lbs150 \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×(1+(3×0.03)0.03)=200×1.06=212 lbs200 \times (1 + (3 \times 0.03) – 0.03) = 200 \times 1.06 = 212 \text{ lbs}


Calculation Example

Weight Lifted (lbs) Number of Reps Estimated Max Lift (lbs)
150 5 168
200 3 212
