    Earlier this week I went to the gym for the first time in a while, and while the actual running was absolutely fine (no pain, trouble breathing etc) the minute I stepped off the treadmill I felt really dizzy and I had to take a minute to steady myself before I could carry on walking.

    I was wondering if it's just because I'm a bit unfit or if I was doing something wrong?

    Oxygen deficit! Not enough oxygen reaching the brain, I used to get this, it'll go as you're body improves at transporting oxygen Just be careful, don't want to pass out while out running or something!

    Lie flat if you are out running and feel light headed, lessens the effect of gravity pulling the bloody down your body rather than up to the head!

    Did you perform a cool down?

    If you're relatively unfit and go from relatively intense exercise to none at all your cardiac output drops dramatically, the blood flow to your brain falls and you then feel faint/dizzy. On the other hand if you reduce the intensity of your workout gradually you enable your body to go some way towards correcting it's oxygen debt and lowering it's cardiac output gradually.
