When you're on a mission to lose weight and get healthy, it can sometimes feel like every calorie counts. Although it's not a good idea to get caught up in counting each and every calorie you consume or burn, it's nice to have a general sense of what your input and output is. We know that strength training is essential for weight loss; it helps you build lean muscle mass, which in turn allows you to shed more fat in the long run. But do you ever wonder how many calories you're burning when you hit the weights?
There definitely isn't a one-size-fits-all type of answer for this, but we can give you an pretty good idea of what you're burning. According to Harvard Medical School, if you weigh 125 pounds, a 30-minute weightlifting session will burn about 90 calories. In that same amount of time, a 155-pound person burns 112 calories, and a 185-pound person burns 133 calories.
