1. What is the Weight Lifting Calorie Formula?

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

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

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

3. Importance of MET Values

Details: MET values represent exercise intensity. Common weight lifting METs:

• Light effort: 3.5 MET
• Moderate effort: 5.0 MET
• Vigorous effort: 6.0 MET
• Circuit training: 8.0 MET

4. Using the Calculator

Tips: Enter MET value based on exercise intensity, your weight in kg, and workout duration in minutes. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How accurate are MET values for weight training?
A: MET values provide estimates. Actual calories burned may vary based on rest intervals, exercise selection, and individual metabolism.

Q2: Should I use kg or pounds for weight?
A: The calculator uses kilograms. Divide pounds by 2.205 to convert to kg.

Q3: Does this account for afterburn effect?
A: No, the formula only estimates calories during the workout. EPOC (afterburn) can increase total calorie expenditure by 6-15%.

Q4: How do I determine the right MET value?
A: Use standard MET tables or fitness trackers that provide exercise-specific MET values.

Q5: Does muscle mass affect calculations?
A: The formula uses total body weight. Those with higher muscle mass may burn slightly more calories than estimated.
