How long should I stay on the treadmill....

For those of you who use the treadmill how long do you stay on it and about how many calories do u burn with in that time. 

i typically do 35 minutes (2 miles at 3.5mph) and i log it as Walking - 3.5 Mph, Level, Brisk, Firm Surface, Walking for Exercise and it's 111 calories; or i crank the incline up to 10%, still 35 min (2 miles at 3.5mph) and log it as Walking - 3.5 Mph, Uphill and it's 174 calories.

incidentally, the treadmill always says i'm burning 250-300 calories, which may be true, but i log the lower numbers here on CC because they sound more in line with the level of exertion i feel like i'm putting in. i have read that walking 12-15 minutes will burn 100 calories, so maybe it is closer to 250-300.

I usually run for 30min about 3miles and treadmill says i burn 375-400 depending on my incline level. sometimes i run straight through and sometimes i do HIIT

I stay on the treadmill for about 45 minutes.  I start out running at 5.5 mph and go as long as I can, lately 30-35 minutes and then I vary the speed to what I feel I can handle until I get to 45 minutes.

The treadmill always says I burn around 650-700 calories but I wear a heart rate monitor also and it usually gives me about 500-525 calories burned.  I always go with the hr monitor.

I usually do the treadmill for 60 minutes a day. Sometimes I've done 90 minutes. I vary it at times and do the different programs for shorter and faster periods to keep it from being boring. Off the top of my head can't think of calorie burn. Depends on how fast I'm going and the distance.

I do 30 - 45 minutes, even 1 hour with 6-7 incline, for 3-5 miles.

I do 45 min-1 hour at the random setting, level 20 (the highest level) at about 3.8 mph.  The machine says I burn around 650 calories but its probably less then that.

Thanks everybody I am hitting the gym tomorrow lets see what I can do on this treadmill and see how long I will actually stay on it. I will keep u posted.  Thanks again...

After a 5 minute warm up on the cross trainer and a round of weights I only do 20 mins on the treadmill, 1 minute walking (6.5) 2-3 mins running (9.5 - 10.5) until I have completed the 20.

Then I do 10 mins either cross training or rowning at moderate intensity.

I do this 2 - 3 times a week, on the other days I just try to incorporate some walking into my daily lifestyle.

I usually do 30-40 minutes.

5 min - warm up

20 minutes - running

5 min - cool down

OR

5 min - warm up

10 minute -  walk on incline

20 minutes - running

5 min - cool down

I run 4 miles a day. 

The time varies from day to day but it is always under 45 minutes.

I normally burn anywhere from 600-650 calories a run. 

I just bang out cardio for 20 min and then concentrate on lifting

My gym owner says that it is not appropriate to run on a treadmill for more than 10 minutes(15 at the most).  I got to know about a 30 minute running programme which I started along with other cardiovascular exercises  and aerobics or strching etc . I work out on cross trainer for about 10 minutes and do cycling also for almost the same time. I used to do about 10 minutes of brisk walk at 6 kmph n 5-8 min of running at 8kmph. But then on my instructor's insistence i reduced the running time to 5 min & brisk walk for 4-5 minutes. He says that I should walk & run on alternate days since the treadmills cause a harmful impact on kness. I do hv pain in my knees but if I take a break for a day or two it is all fine. I exercise for almost 2 hours everyday but I find runing & walking really helpful in my weight loss. I still need to reduce at least 4 kgs. I want to know if  should further reduce workout on treadmill. And does it make difference if you take support of the arms while running on treadmill or you run slower but without support?

I keep my treadmill session short, but very intense. No more than 10mins.

The hardest thing to overcome on a treadmill is the boredom! I don't know how people can spend an hour on them!

30-60 varying between 2.5-3.5. Whatever pace song is in the mp3 determines my speed. 2-3x per week

On days that I do circuit training (one so far haha) I walk 20 minutes afterwards. 2x week (went yesterday upper, going tomorrow for lower)
