How can I calculate calories used by weight lifting?
Calculating the number of calories burned during weight lifting can be done using different methods. The most accurate method involves measuring your oxygen consumption and carbon dioxide production during the workout using specialized equipment. However, estimating the calories burned using equations that consider your weight, the intensity of your workout, and the duration is a more practical approach.
One such equation is the Harris-Benedict-Roifflin (HBR) equation:
Calories burned = (10 x weight in kg) + (6.25 x height in cm) - (5 x age in years) + (s x activity factor)
where s = 9 for weight lifting or other resistance training.
Another method is the MET (Metabolic Equivalent of Task) method:
Calories burned = MET x weight (kg) x duration (hours)
where MET = 4-8 for weight lifting or other resistance training.
Remember, these equations provide only an estimate, and individual factors like fitness level, muscle mass, and technique can influence the actual calorie expenditure.

How many calories can I burn in a 30-minute weightlifting session?
- Depending on factors like weight, intensity, and efficiency, the calorie burn can range from approximately 150 to 400 calories.
How can I maximize calorie burn during weightlifting?
- Lifting heavy weights, using compound exercises, and minimizing rest periods can increase calorie expenditure.
Is it important to warm up and cool down before and after weightlifting?
- Yes, warming up prepares your body for the workout and reduces the risk of injury, while cooling down helps with recovery and reduces soreness.
