Calories Burned Calculator

Formula

The formula to calculate calories burned is:

\[ C = \text{IF} \times \frac{3.5 \times (\text{BW}/2.20462)}{200} \times T \]

Where:

\( C \) is the total calories burned
\( \text{IF} \) is the intensity factor (3.5 for light, 5 for heavy)
\( \text{BW} \) is the body weight in pounds (lbs)
\( T \) is the time in minutes

What is Calories Burned Calculation?

The calories burned calculation is used to estimate the total energy expenditure during strength training by converting body weight from pounds to kilograms and adjusting for the intensity and duration of the exercise.

Example Calculation

Let's assume the following values:

Intensity Factor (\( \text{IF} \)): 3.5
Body Weight (\( \text{BW} \)): 150 lbs
Time (\( T \)): 30 minutes

Step 1: Convert body weight to kilograms:

\[ \text{BW} = 150 / 2.20462 \approx 68.04 \text{ kg} \]

Step 2: Calculate calories burned:

\[ C = 3.5 \times \frac{3.5 \times 68.04}{200} \times 30 \approx 125.01 \text{ calories} \]

Therefore, the total calories burned is 125.01.
