The title says it all! I've been running for around 3 months, usually about 3 times a week but it varies due to the kids' schedule. I can only jog for about 45 seconds to a minute before I lose my breath and I have to walk again (usually for 45 seconds to a minute also). And I can only go about a mile before I'm pooped!!

I don't get it! I'm in reasonably good health (5'6" ~135 lbs), I keep reasonably active (jog, bike, run after the kids).. but I can't get past this wall! It's incredibly frustrating, especially because I have a fitness test that I need to pass next month and I need to run 1.5 miles in a certain amount of time.

I get so out of breath and exhausted that I can't go further, usually my chest will get tight so that doesn't help the breathing issue. What am I doing wrong? What is wrong with me!?
