Fat is the accumulation of excess energy. If you don’t burn off the calories you consume, they will be stored as fat. If you build muscle mass, you will not only feel better and look leaner, you will actually start to burn fat at a much faster rate.
That’s because muscles tissue is an incredible fat-burner. The more lean muscle mass you have, the more calories you burn, even at rest. With that in mind, it makes sense to add strength training to your weekly routine.
First, find out how much of your body is made up of fat, and how much is made up of lean muscle. This measurement is your body fat percentage. You can find guides online which help you determine your body fat percentage, but if you’re a first-time measurer, you might get better results by asking your doctor or fitness trainer to measure it for you.
Some “smart” scales can even calculate your body composition by sending a painless signal through your body. The signal returns data that tells you how much of your weight comes from fat, muscle, bone, and fluid.
A healthy body fat percentage for women ranges from 14% (for a young, athletic woman) to 35% (for women over 65). Males have more natural muscle mass than females, so men can be healthy with body fat percentages between 6% and 25%.
