1. What is the Calories Burned Equation?

The calories burned equation estimates energy expenditure during weight lifting using MET (Metabolic Equivalent of Task) values. It accounts for body weight and duration of activity.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• 6 — MET value for weight lifting (moderate effort)
• 3.5 — Oxygen consumption at rest (mL/kg/min)
• weight_kg — Body weight in kilograms
• minutes — Duration of activity in minutes

Explanation: The equation calculates calories burned by multiplying the metabolic cost of the activity by body weight and duration.

3. Importance of MET Value

Details: MET values represent the intensity of physical activities. Weight lifting typically ranges from 3-6 MET depending on intensity.

4. Using the Calculator

Tips: Enter your weight in kg and duration in minutes. For accurate results, use your current weight and actual workout duration.

5. Frequently Asked Questions (FAQ)

Q1: Why use MET=6 for weight lifting?
A: MET=6 represents moderate effort weight training. Adjustments may be needed for very light or intense sessions.

Q2: How accurate is this calculation?
A: It provides a reasonable estimate but individual factors like muscle mass, rest periods, and intensity affect actual calories burned.

Q3: Should I include warm-up time?
A: Only include active lifting time, as warm-up typically has lower intensity (lower MET value).

Q4: Does this account for afterburn effect?
A: No, this calculation only estimates calories burned during the activity, not the additional calories burned afterward.

Q5: How does body composition affect results?
A: Muscle burns more calories than fat at rest, but this calculation uses total body weight as a general estimate.
