If you're trying to lose those last stubborn pounds for an upcoming wedding or to fit better in your bikini, kicking it up a notch in the cardio department is a surefire way to torch calories and slim down. When monitoring your progress with a scale, you may notice the numbers staying the same or actually going up instead of dropping down as expected. So what gives?
When it comes to losing weight, try to think about it this way. You want to lose fat, but that doesn't necessarily translate to losing pounds as measured by a scale. When increasing your cardio workouts, you'll gain more muscle, and while muscle doesn't weigh more than fat, it is more dense, which means a pound of muscle takes up less space than a pound of fat. So even though you're losing body fat, the muscle you gain explains why you're heavier when stepping on the scale.
Try not to worry too much about what the scale says, since weight isn't necessarily an accurate way to determine how healthy and fit you are. It's better to keep an eye on how toned you look in the mirror and how you feel when slipping on your clothes. If you can tell you're slimming down, then you know all your hard work is paying off.
