If you've been working out a lot in an effort to lose weight, it can be devastating to step on the scale and find that you've lost nothing at all or, even worse, gained a pound. You complain about it to your friends, and they all say the same thing, "It's probably just muscle!" which you wave off as hogwash. I mean, does muscle actually weigh more than fat? Could you drastically improve your body while maintaining the same number on the scale?

Well, Adrienne Osuna, a fitness blogger based in Santa Maria, California, is here to prove that you definitely can. As the mother of four precious boys, Adrienne struggled for years with her weight, going back and fourth with yo-yo dieting. Finally, she decided that the key wasn't to stop eating, but to start working out, and to stop obsessing about the scale.

"I lost 60 pounds then I quit dieting (always gaining and losing weight and yo-yo dieting and I was so over it.)" she wrote on her blog. "I started heavy lifting and feel in love. I recompositioned my body with out dieting. I lifted heavy 4x a week and I intermittent fasting. Within a year or so if that I was down 3 dress sizes and the scale still hadn't moved. But everyone kept telling me how I looked so good and asking how much I lost which was really encouraging!"

Last week, she shared a before/after photo of her progress. As you can see in the photo, she's only lost two pounds, but she looks so much leaner and more toned, because she lost fat and gained muscle.

"This was all hard work in the gym lifting heavy weights and intermittent fasting," she wrote in the caption. "And for anyone just seeing this for the first time YESSS really 2 lbs, the scale doesn't measure fat vs muscle!"

So remember that the next time you step on the scale after an intense workout!
