    • Brzycki Formula
    • Lombardi Formula
    • Mayhew Formula
  6. Copy or Share Results
    Use the Copy button to save your results to your clipboard or the Share button to post your 1RM on social media.
  7. Reset if Needed
    Click the Reset button to clear the fields and enter new numbers for another calculation.

Practical Example

Imagine you lifted 200 lbs for 8 reps. Using the Max Deadlift Calculator:

  • Epley Formula: 200 × (1 + 8/30) = 253.33 lbs
  • Brzycki Formula: 200 × (36 / (37-8)) = 246.55 lbs
  • Lombardi Formula: 200 × 8^0.10 ≈ 224.89 lbs
  • Mayhew Formula: (100 × 200) / (52.2 + 41.9 × e^(-0.055×8)) ≈ 248.12 lbs

This gives a comprehensive view of your estimated one-rep max, helping you plan future lifts safely and effectively.

Frequently Asked Questions (FAQ)

  1. What is a one-rep max (1RM)?
    Your one-rep max is the maximum weight you can lift for a single repetition of a given exercise.
  2. Why use a calculator instead of lifting max weight?
    It prevents injury and provides a safe estimate without physically lifting your maximum.
  3. Which formulas are used?
    Epley, Brzycki, Lombardi, and Mayhew formulas are used for calculating estimated 1RM.
  4. Can I enter weight in kg?
    Yes, the calculator supports both pounds and kilograms.
  5. What if I lift fewer than 1 rep?
    The calculator requires at least one repetition to produce results.
  6. Can I use it for exercises other than deadlift?
    While designed for deadlifts, it works for other resistance exercises.
  7. Is it accurate for beginners?
    Yes, it gives a reasonable estimate, though real-life max may vary slightly.

  12. What is the Epley formula?
    Epley estimates 1RM using the formula: weight × (1 + reps ÷ 30).
  13. How does the Brzycki formula work?
    Brzycki formula: weight × (36 ÷ (37 − reps)) estimates your max based on reps.
  14. Is Lombardi formula different?
    Lombardi uses a power-based formula: weight × reps^0.10.
  15. What about Mayhew?
    Mayhew formula calculates 1RM using an exponential formula based on reps and weight.
  16. Can I share results on social media?
    Yes, there’s a built-in share feature for platforms like Twitter.
