1. What is 1RM?

The 1RM (One Repetition Maximum) is the maximum amount of weight you can lift for a single repetition of a given exercise. It's a common measure of strength in Old School RuneScape (OSRS) and real-world strength training.

2. How Does the Calculator Work?

The calculator uses the Epley formula:

Where:

• \( Weight \) — The weight lifted (kg)
• \( Reps \) — Number of repetitions performed (1-10)

Explanation: This formula estimates your maximum strength based on how much weight you can lift for multiple repetitions.

3. Importance of 1RM Calculation

Details: Knowing your estimated 1RM helps in setting appropriate training weights and tracking strength progress in OSRS and real-world training.

4. Using the Calculator

Tips: Enter the weight you lifted and how many reps you performed (between 1-10). The calculator will estimate your 1RM.

5. Frequently Asked Questions (FAQ)

Q1: Why use 1-10 reps for calculation?
A: The formula is most accurate in this rep range. Beyond 10 reps, other formulas may be more appropriate.

Q2: How does this relate to OSRS strength levels?
A: In OSRS, your strength level determines your maximum hit. This calculator helps estimate your real-world strength equivalent.

Q3: Should I actually test my 1RM?
A: For safety, it's better to estimate using this calculator rather than attempting maximal lifts without proper preparation.

Q4: Does this work for all exercises?
A: It works best for compound lifts like squats, deadlifts, and bench press. Accuracy may vary for isolation exercises.

Q5: How often should I recalculate?
A: Recalculate every 4-6 weeks as your strength changes with training.
