1. What is the Calories Weight Lifting Calculator?

The Calories Weight Lifting Calculator estimates the number of calories burned during weight lifting activities using the MET (Metabolic Equivalent of Task) formula. It provides an accurate assessment of energy expenditure based on body weight, exercise duration, and intensity level.

2. How Does the Calculator Work?

The calculator uses the MET formula:

\[ Calories = MET \times Weight_{kg} \times Time_{hr} \]

Where:

\( MET \) — Metabolic Equivalent of Task (5-6 for weight lifting)
\( Weight_{kg} \) — Body weight in kilograms
\( Time_{hr} \) — Exercise duration in hours

Explanation: The MET value represents the energy cost of physical activities. Weight lifting typically ranges from 5 MET (light intensity) to 6 MET (vigorous intensity).

3. Importance of Calories Calculation

Details: Accurate calorie estimation is crucial for weight management, exercise planning, and understanding energy expenditure during strength training activities.

4. Using the Calculator

Tips: Enter your weight in kilograms, exercise time in hours, and select the appropriate MET value based on your workout intensity. All values must be valid (weight > 0, time > 0).

5. Frequently Asked Questions (FAQ)

Q1: What are MET values?
A: MET (Metabolic Equivalent of Task) is a unit that estimates the energy cost of physical activities. One MET equals the energy expenditure while sitting at rest.

Q2: Why use different MET values for weight lifting?
A: Different intensities of weight lifting require different energy expenditures. Light weight lifting (5 MET) involves lighter weights and more repetitions, while vigorous weight lifting (6 MET) involves heavier weights and higher intensity.

Q3: How accurate is this calculation?
A: The calculation provides a good estimate for most people, but individual factors like metabolism, muscle mass, and exercise efficiency can affect actual calorie burn.

Q4: Should I include rest periods in the time calculation?
A: Only include active lifting time. Rest periods between sets should not be included as they significantly reduce calorie burn.

Q5: Can this calculator be used for other strength training exercises?
A: While designed for weight lifting, it can provide estimates for similar strength training activities, though MET values may vary for specific exercises.
