Stuttering and Physical Fitness?

Stuttering and Physical Fitness? Anyone else here go to the gym pretty frequently who stutters? I’ve started lifting and going to the gym pretty frequently over the past 2 years and I’ve noticed that my stutter has decreased quite a bit. My stutter only flairs up anytime when I miss the gym (for example last week I took 3 off days) and I started to notice it again at work. Stuttering is such a unique and complex issue and was wondering if anyone had a similar experience.
