Weight Lift Max Calculator

Achieving your maximum weight lift is a crucial aspect of strength training. Whether you’re a seasoned lifter or just starting, knowing your one-rep max can help tailor your workout routine for optimal results. Our Weight Lift Max Calculator simplifies this process, providing you with an estimated maximum weight lift based on the weight and repetitions you input.

Formula: The calculation is based on the Epley formula: (weight lifted) × (1 + 0.0333 × number of repetitions). This formula estimates your one-rep max by taking into account the weight lifted and the number of repetitions performed.

How to Use:

  1. Enter the weight you lifted in the designated field.
  2. Input the number of repetitions you completed.
  3. Click the “Calculate” button to get your estimated one-rep max.

Example: For instance, if you lifted 200 pounds for 8 reps, the calculation would be (200) × (1 + 0.0333 × 8) = 266.64 pounds. The calculator would display: “Your estimated one-rep max is: 266.64 pounds.”
