excessive cardio = bad?

Just wondering if doing excessive cardio work... can it be a bad thing?

I only ever used to do 10 minutes a time, but now ive worked my way up from regaining fitness and now I can do an hour easily on a crosstrainer machine, I slipped it onto fat burn yesturday, and burnt a monsterous 1000 calories in one go :eek:

Although it stupidly good exercise, are there any drawbacks? There normall are, too much of a good thing being a bad thing, or is it Ok do burn 1000 calories in a session, 3-4 times a week?

Also theyve started selling a new drink at the gym with 'added carbazine' I think it was - claims to help burn off bodyfat during a workout... does anyone know what this chemichal is, if it actually works and probably more importantly, is it good for you?

How long did you do to burn 1000 cals?

It was an hour, well, 65 mins, 60 mins + 5 mins cool down so I dont get a heart attack

I sweat like nobodies business by the time I'm finished and I just thought whoa, 1000 is a big number, might not necessarily be a good thing

It doesnt really seem like hard work (Well, too much) to burn off 1000 calories, as In half an hour on a rower I struggle to hit 350, and after that I find it hard to move

On a cross trainer I could just go all day

Yeah I dont expect it to be accurate but just close, the question was will it do any harm

And it looks like a no no

So thats good

Cant remember for the life of me what the chemichal they put in the drinks, I bet its probably not good for you, but its going to be annoying me all day if I cant think of it after I stared at it for 10 minutes trying to remember

our cross trainers are quite crap tho, although they do measure your heatrate it only rarely comes on the screen, going to have to buy one of them heart rate monitors myself as i want to be in the fat burning zone
