I haven't been working out much at all since the start of this year and I've noticed my stutter getting worse day to day and my self confidence has hit a low point. That being said, when I was in a routine of going to the gym and working daily there was a increase of my fluency and I would stutter very little! I'm going to try my best to get back into that routine. I've never posted on Reddit before and it's good to know that there are people in the same boat.
