1. What is Relative Strength?

Relative Strength is a measure of your strength in relation to your body weight. It's calculated by dividing your one-repetition maximum (1RM) lift by your body weight. This metric helps compare strength across individuals of different sizes.

2. How Does the Calculator Work?

The calculator uses the Relative Strength formula:

Where:

• \( 1RM \) — Your one-repetition maximum weight lifted (kg)
• \( Bodyweight \) — Your current body weight (kg)

Explanation: The formula shows how much weight you can lift relative to your own body weight, providing a fair comparison between individuals of different sizes.

3. Importance of Relative Strength

Details: Relative strength is crucial for athletes in weight-class sports, climbers, and anyone interested in functional strength. It helps assess true strength potential without the advantage of larger body mass.

4. Using the Calculator

Tips: Enter your 1RM (heaviest weight you can lift for one repetition) and your current body weight, both in kilograms. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a good relative strength score?
A: For most compound lifts, a score of 1.0 is decent, 1.5 is good, and 2.0+ is excellent for trained individuals.

Q2: Does this work for all exercises?
A: It's most meaningful for compound lifts like squats, deadlifts, and bench press. Less applicable for isolation exercises.

Q3: How often should I measure my relative strength?
A: Every 4-8 weeks is reasonable to track progress without overtesting.

Q4: Should I use estimated or tested 1RM?
A: Tested 1RM is more accurate, but estimated from multiple reps can work if you can't safely test 1RM.

Q5: Does body fat percentage affect relative strength?
A: Yes, leaner individuals typically have better relative strength as they carry less non-functional weight.
