1. What is the Weight Lifting Calorie Formula?

The weight lifting calorie formula estimates calories burned during weight training based on MET (Metabolic Equivalent of Task) value, body weight, and exercise duration. It provides a scientific way to quantify energy expenditure during resistance training.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( MET \) — Metabolic Equivalent of Task (dimensionless)
• \( weight \) — Body weight in kilograms
• \( time \) — Exercise duration in minutes

Explanation: The formula accounts for exercise intensity (MET), body mass, and duration to estimate total energy expenditure.

3. Importance of Calorie Calculation

Details: Accurate calorie estimation helps with weight management, exercise programming, and nutritional planning for fitness goals.

4. Using the Calculator

Tips: Enter MET value (typically 3-6 for weight lifting), your weight in kg, and exercise duration in minutes. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are typical MET values for weight lifting?
A: General weight training: ~3-6 METs. Vigorous weight lifting: ~6-9 METs. Exact value depends on intensity and rest periods.

Q2: How accurate is this calculation?
A: It provides a reasonable estimate (±20%) but individual metabolism and exercise form can affect actual calories burned.

Q3: Should I include warm-up time?
A: Only include active lifting time. Warm-ups typically have lower MET values and should be calculated separately.

Q4: Does this account for afterburn effect (EPOC)?
A: No, this calculates only calories burned during the exercise session. Weight training can increase metabolism for hours afterward.

Q5: How does body composition affect results?
A: Muscle burns more calories than fat at rest, but the formula uses total body weight for simplicity during exercise.
