the benefits of a rest day

One of my coworkers asked me this morning if I had been losing weight. I have not, but it made me feel so great, especially because I felt bloated this morning and am wearing clothing that is a bit loose. I feel confident that I am likely gaining muscle and losing fat, since my weight on the scale is the same, but I am getting a lot stronger in the gym. I mentioned this to my coworker and told him about my newfound rest day once a week, and he confirmed the benefits of a rest day and encouraged me to that end. Thanks, bro, for making my day.
