Been working on my cardio lately trying to get it up.
Just wondering what the recovery time for it is.
For example, say i run 2 miles today, and get puffed. Run 3 miles tomorrow and get puffed. 4 Miles next day and so on.
Does your cardiovascular system need substantial recovery time like weight training does?
Obviously people are different, but have there been any studies anyone is aware of that document the bodies ability to gain and lose cardio endurance?
