Mind you I wouldn’t call pumping iron despite your screaming muscles a particularly efficient way to improve your ability to speak in public despite your screaming brain. But it certainly helps. Some relevant mediating factors:
Improved willpower and self control.
Decreased salience of psychological distress—you can feel the discomfort without it needing to control or define you.
Increased testosterone levels promote social risk-taking.
Physical conditioning increases self esteem—your perception of your own status. The instinct to not draw public attention—and not place yourself above your station—is intrinsically linked to your relative status levels.
Exercise changes posture. Even things as simple as standing differently change how difficult public speaking is!
