How to Use the Deadlift Max Calculator

This step-by-step guide will assist you in effectively using the Deadlift Max Calculator to estimate your one-rep max (1RM) using different formulas.

Step 1: Enter Your Weight Lifted

First, navigate to the input field labeled Weight Lifted (lbs/kg). Enter the amount of weight you lifted during your deadlift. Ensure the weight is between 1 and 2000, as the calculator will not accept values outside of this range. Use increments of 0.5 if needed.

Step 2: Enter the Number of Repetitions Performed

Next, locate the input field labeled Repetitions Performed. Input the total number of reps you completed with the weight previously entered. Valid entries are between 1 and 20 repetitions. Use whole numbers as the calculator doesn’t accept fractions for repetitions.

Step 3: Select a Calculation Formula

Now, move to the field labeled Calculation Formula. You will find a dropdown menu containing several formula options: Brzycki, Epley, Lander, and Lombardi. Select the formula you wish to use to estimate your 1RM. Note that each formula has unique characteristics and may yield slightly different results.

Step 4: Review the Calculated Results

After completing the inputs, the calculator will display your estimated one-rep max based on the selected formula.

  • If you selected the Brzycki Formula, your 1RM will be calculated using: weight * (36 / (37 – reps)).
  • If you selected the Epley Formula, your 1RM will be formulated as: weight * (1 + 0.0333 * reps).
  • If you chose the Lander Formula, your 1RM computation will be: (100 * weight) / (101.3 – 2.67123 * reps).
  • If you opted for the Lombardi Formula, your 1RM will come from: weight * pow(reps, 0.10).

Step 5: Use the Training Percentages

The calculator will also provide estimated training percentages based on your calculated 1RM. This is helpful for designing a training program tailored to different intensity levels.

Follow these instructions carefully to ensure an accurate estimation of your deadlift one-rep max using this versatile calculator.
