1. What is Deadlift One Rep Max?

The Deadlift One Rep Max (1RM) is the maximum amount of weight you can lift for one complete repetition of the deadlift exercise. It's a common measure of strength in weight training.

2. How Does the Calculator Work?

The calculator uses the deadlift 1RM equation:

Where:

• \( deadlift \) — Weight lifted (kg)
• \( reps \) — Number of repetitions performed (1-36)

Explanation: This formula estimates your one-repetition maximum based on your performance with submaximal weights. The equation accounts for the relationship between repetitions and percentage of 1RM.

3. Importance of 1RM Calculation

Details: Knowing your 1RM helps in designing training programs, tracking strength progress, and setting appropriate training loads for different goals (strength, hypertrophy, endurance).

4. Using the Calculator

Tips: Enter the maximum weight you can deadlift for the given number of repetitions. For best results, use a weight you can lift for 2-10 reps. All values must be valid (weight > 0, reps between 1-36).

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculator?
A: It provides a good estimate but actual 1RM may vary by ±5-10% depending on individual factors like fiber type composition and training specificity.

Q2: Should I test my actual 1RM?
A: Only if you're an experienced lifter with proper technique and spotting. Beginners should stick to estimates.

Q3: Does this work for other exercises?
A: This specific formula is optimized for deadlift. Other exercises may require different formulas.

Q4: How often should I recalculate my 1RM?
A: Every 4-8 weeks as your strength changes, or whenever you can do more reps with the same weight.

Q5: Why can't I enter more than 36 reps?
A: The formula becomes increasingly inaccurate with very high rep ranges, which typically measure endurance more than maximal strength.
