1. What is 1RM?

1RM (One Repetition Maximum) is the maximum amount of weight you can lift for a single repetition of a given exercise. It's a standard measure of strength in weight training.

2. How Does the Calculator Work?

The calculator uses the Strength Level 2 equation:

Where:

• \( Weight \) — The weight lifted (kg or lbs)
• \( Reps \) — Number of repetitions performed

Explanation: This equation estimates your 1RM based on submaximal loads, with coefficients optimized for strength level 2 athletes.

3. Importance of 1RM Calculation

Details: Knowing your 1RM helps design training programs, track progress, and set appropriate weights for different rep ranges.

4. Using the Calculator

Tips: Enter the weight you lifted and how many reps you performed with that weight. Use the same unit (kg or lbs) consistently.

5. Frequently Asked Questions (FAQ)

Q1: What is Strength Level 2?
A: Strength Level 2 refers to intermediate lifters who have moved beyond novice level but aren't yet advanced.

Q2: How accurate is this calculator?
A: It provides a good estimate for most intermediate lifters, but actual 1RM may vary based on individual factors.

Q3: Should I test my actual 1RM?
A: For beginners, estimation is safer. Experienced lifters can test actual 1RM with proper preparation and spotting.

Q4: Can I use this for all exercises?
A: It works best for compound lifts like squats, bench press, and deadlifts. May be less accurate for isolation exercises.

Q5: How often should I calculate my 1RM?
A: Every 4-8 weeks to track progress, or whenever you significantly increase your training weights.
