I've known people with asthma who have overcome it with cardio, compared to people who have asthma and don't try to run. The people who have had asthma when they were younger and did run were able to do so when they got older.
Also here is a video of VERY strong pls who don't look that fat who can't even complete ONE lap this is just sad imo. Sure you can be strong that is great but if you can't do basic activities without your heart going out its pretty useless. http://youtube.com/watch?v=IAsv_WhHPVU
Now I want to be a well rounded athlete so I was just trying to see what the strong athelets-if they do- do to keep endurance up.-You hear about bodybuilders endurance lacking all the time in posing, maybe if they did cardio they could have better performances-
Also the whole Jesse thing I used him as an example to get some discussion going, you don't know if he actually trained his heart much more if he could have avoided his accident. I think he is a great guy and was tragedy but can't tragedies be avoided or at least somewhat prepared for?
Go to my previous post to see what I think of the medical condition feel free to clear it up I didn't look into the medical jargon too much.
