The relative percentage of fat, muscle, bone, and other tissue in the body. Too many people people lose the battle of weight loss because of what the scale reads, but that is only half the battle! Your body fat percentage will give you a more accurate breakdown of the progress you have made. Since muscle is denser than fat, it is possible to lose fat and gain muscle tone, resulting in little or no change reflected on the scale.
Talk to a trainer to make an appointment to get yours checked.
