Near Fainting after Gym Induction

Hi
I lead a relatively sedentary lifestyle and exercise only occasionally which is usually a short jog or sets of push ups/sit ups
I havn't done any regular exercise since leaving college 4 years ago
I'm now 21, 6" 1, Weigh roughly 11 stone 3 pounds

So i decided to join a gym to improve my general fitness and eventually build some muscle mass
I had my gym induction earlier today and the instructor showed me and a friend how to use the treadmill, bikes, rowers and crosstrainers. She did not ask about my lifestyle or my general health other than if i had diabetes .etc. and she pushed us what i would consider to be way too hard for someone who hasnt maintained any exercise for that long. Having had no warm up (i had had breakfast) we were spending roughly 7-8 minutes on each machine on quite fast/resistant settings on each machine quickly after one another
After getting off the rowing machine and standing talking for 3-4 minutes i began to feel suddenly dizzy and nauseous which gradually worsened to the point where i couldnt see anything at all (it was like a gradual build up of light - felt the same as when you stand up too quick and get a rush of blood to the head) for at least 10 seconds as i stumbled to the toilet. When i sat down it slowly relieved my symptoms. I then stood up shortly after and they began to worsen again.
Can anyone suggest if this is just a natural reaction to the shock of over-exertion or could there possibly be some other medical reason for this happening?

My friend is in a similar situation and also had similar symptoms however they were much more mild

Thanks for your help

Excessive physical exertion in a person in relatively poor physical condition can cause the symptoms you describe. So be smart, and introduce your body to physical activity in a reasonably slow and planned manner. In the long run that will be best both for your physical development and cardiovascular health.
