The treadmill & HGH?

I’ve noticed that people who take HGH run on the treadmill like everytime they go to the gym. why is this? Is this bcz they want to keep the heart healthy? Or for some other reason? Curious… lmk

there are plenty of bodybuilders who use HGH and the last time they've been on a treadmill was 10 years ago
