excessive cardio = bad?

during winter training i usually do 1 hour a time on the rower and burn around 1250/1300 cals and i do that 4/5 times a week along with weights and ive never had any problems

What sort of level would you be thinking?

Training every day for over an hour would probably push you into overtraining if you weren't used to it, and sometimes even if you were. Rest periods are at least as important as the workout period.

If you lined up four top athletes, put one on a treadmill, bike, rower and x-trainer, wired them up with proper scientific gear and challenged them to see who could burn the most calories in an hour I'd have the x-trainer as coming last everytime.

I would have the bike last tbh.
treadmill
xtrainer
rower
bike
 
I wouldn't go off what the readouts on any of the machines in the gym say, it's all way too generic and simple to be accurate at all.
 
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 :p

1000 is perfectly possible tho, ill check what i do in 10 mins tomorrow. I think it might be somewhere between 150 and 200!

If the readout on the cross trainer is to be believed then 1000 calories in an hour is easily possible, I can get over 1300 if I'm going at a decentish pace. (none of this wishy washy doing 5mph on level 1 stuff though)

Surley it is down to effort ~ I also use the X-trainer as follows -

1 hour ~ 200/210 Watts average ~ HR 130/150 ~ 1020 Calories used (I think it uses watts/time/weight to give this figure).

I cycle off-road and climb/hill walk and use this excise for general fitness and think that outside of a class/personal trainer, it is in my opinion the best work out in the gym for time/effort.
 
i think you might be right tbh, all the machines i use (xtrainer) ask for your weight before you start (unless you do quick start), so i imagine the intensity / speed / weight calculate the eqivalent calories your losing.
 
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 :)
 
That is true but is irrelevant. The machine will need "X" amount of energy exerted on it to make it run one cycle/revolution in "Y" amount of time. This will give you a value of energy spent neccessary to move the machinery.

irrelevant? hardly, calories burnt depends on your body weight, body fat %, level of fitness etc. Put someone on a treadmill with 10% body fat and another with 30%, doing identical workouts the 10% person will burn more calories. Thats only 1 factor. Gym machines are usually out by 10-30%.

As I said, its true but irrelevant. A machine is never going to know all the parameters to work out all the neccessary calculations to know what the energy spent was for all cases. Therefore it can only work within its limited knowledge based in the minimal inputs you feed it.

Any work done on the machine will need energy to run it. The distance travelled, resistance (force) and time will give you all the parameters to work out how much energy you have expended.

Work = Force x Distance
The unit for work is Joules. Over time 1 Joule per second = 1 Watt which either can be converted to calories.

This is all the machine can probably deal with which is why the rest is irrelevant and where the error comes in.
 
if you row properly then it can be either fat burning or cardio and uses more muscles as the treadmill as you use legs and back and arms whereas the treadmill uses legs only
