The formula to calculate the Kettlebell Calories (KBC) is:
\[ KBC = KBT \times 20 \times \frac{BW}{150} \]
Where:
Let's say the total kettlebell time (KBT) is 30 minutes and the body weight (BW) is 180 lbs. Using the formula:
\[ KBC = 30 \times 20 \times \frac{180}{150} \]
We get:
\[ KBC = 720 \text{ calories} \]
So, the total calories burned during the kettlebell exercises is 720 calories.
