Fat experiences

If you get past 300 or so, you won't be running regularly anymore. It would be too cumbersome and awkward.

Well it definitely all depends on your stamina and weight. I think it’s fair to say that most people 220+ wont jog 5km. I can’t anymore, I don’t want to anymore. But I’ve had to sprint in some occasions for work, healthcare worker here, and I was astonished that I could still sprint for 100-200 meters and only be moderately out of breath for less then a minute.

The power of adrenline, lol.

But yeah. If you keep your strength and cardiovascular health in good shape, you won't tire as easily.

It's like how people at normal weights can be out of breath after doing very little.

People seem to forget that being fat doesn’t equal being massively out of shape. If you keep working out, you can be fat and in shape. Sure you’ll never be able to be athletic. But you don’t have to be wheezing and out of breath everytime you get up just because you weigh 300+ pounds.
Ever seen the strongest people alive, they all have a pretty good layer of fat over their muscles.

This is true. Idk what part of the healthcare industry you're in, but I do know a lot of y'all need to be in fairly decent shape.

There is an inevitable inertia to being that heavy, and it only increases with weight. Even in shape, people aren't made to lug around 300-, 400-, 500-pound plus bodies.

You might be able to get away with the 300 range depending on body composition. But 400+? Yeah, your speed and stamina are taking a hit.

I definitely can’t run far, I haven’t been able to for years. I get tired too quickly, plus I hate being out of breath. I’ve been out of shape for years and that’s probably not going to change anytime soon!

I can probably do short sprints alright (of course I haven't checked recently) but I'm pretty sure i'd suck at any sustained running. I've noticed in the past 30 pounds or so that I even walk noticeably slower than I used to, which is kind of a turn on TBH.

I always hated running even when I was skinny.
If I ran now my flab would probably beat me to death.
