Im just wondering about weight gain due to muscle growth. My wife has been working out for some time with weights and cardio training, but she is finding that her weight has been fluctuating and at times gains weight a little bit.
A pound of fat and a pound of muscle weigh the same. The difference is that a pound of muscle is denser, and therefore, takes up much less surface area, than fat. If you were to look at five pounds of muscle and five pounds of fat, the fat would take up much more volume. It is possible for you to lose fat and gain muscle without a change in body weight because you are building muscle through exercising. Sometimes, your body fat percentage can be a better indicator than the number on the scale, and you can get this tested by a medical professional.
