Is it alright to do cardio for more than an hour, say between 1 and 3 hours a day?

Yeeeeessss I know strength training is important and such and I incorporate that too (around 3 times a week.) so please no 'OMGZ UR A CARDIO BUNNY DNT U NO MUSCLE WEIGHS MOAR THAN FAT?/1 CARDIO IS EVIL'. Haha.

My question is, will doing that amount of cardio daily harm me in any way? I genuinely enjoy working out and I always try to eat my exercise calories.. I mean the sort of thing I like to do is go for a run and then come back and jump on the stationary bike and watch Dexter or Battlestar Gallactica for an hour or more. It's something I enjoy, I'm not trying to be a *kitten* and lose 10lbs in a week or anything, I just enjoy exercising and feeling the drastic improvement in my endurance week after week.

Any help is appreciated :)

    i dont really know, i dont think it will hurt you but from my understanding after an hour of cardio you hit the point of diminishing returns.

    It won't hurt you if you are eating to fuel it...it just won't help you any more after a certain point...
    And please take a rest day once a week. If you get injured, you won't be able to run at ALL for a while and that would be worse, right?

    OMG! I do the same thing! Walking/running on the treadmill is the only time I get to really watch MY shows! I started on season 1 of Smallville, I am now on season 7. I'm on the treadmill 1-2 hours a day, 5 days a week. I weight train 2x a week. You are fine as long as you allow yourself recovery time or active rest (meaning brisk walk for 15-20min on one day, etc). I enjoy it cause it's "my time". Once I finish Smallville I might go back through all the Supernaturals from season 1 (one of my other fave shows)!

    Enjoy your time on the treadmill, just make sure you have off days/recovery days.

    No it is not. Cortisol problems and adrenal fatigue.
    Top 6 h/week.
    Read this article and go over the nutrition point. 6 meals/day not really accurate now.

    It seems that you already know the answer but you don't want to hear it again. If you are a competitive athlete eating a lot and monitoring everything then you may be able to do it but the question is: are you?
    Bottom line. You won't be able to sustain this effort for long. :smile:

    I'm a running junkie so I know where you are coming from. Seems like you know what you are doing, you are getting in the strength training as well as the cardio, and you are eating back exercise calories from your epic burns, so I don't think you are doing any great harm to yourself. Building the endurance and the stamina always motivates me to go go go as well. Just listen to your body and don't over exert yourself beyond what it is telling you.

    you'll be fine- i have family members that train for triathalons, and you can bet they do more than an hour of cardio a day. As long as you're smart about it (which it sounds like you are, eating your calories back and incorporating strength training) then you can sit back (or stand up) and enjoy! :)

    I never heard about the 'diminishing returns' after the one-hour theory, but would like to know more on that. I do an average of 180 to 200 minutes a day, as I am not in employment, and it gets me out. This has been my pattern over the last year. I don't eat much back from that, and don't see how people can stuff an extra 1000+ calories in on top of the stated allowance. So far I lost 27lbs and have 13 to go

    This is my opinion only, but I don't think there is a problem so long as you are eating well and getting good rest. Otherwise, you risk overtraining and burnout.

    Long workouts will tend to lean you out (think marathon runner) whereas short burst high intensity work will build you out (think sprinter). Think about the results you want and taylor your workouts and food to meet that. Enjoy!

    If doing more than an hour of cardio was counter-productive to weight loss, all Marathon runners would be obese.

    Yes, the law of diminishing returns applies the longer you go, as you become more efficient at the cardio you're doing and you burn a different amount as you switch between energy stores. However you do still keep burning, albeit at a lesser rate.

    Edit: I noticed in your original post you want to increase your endurance, in which case going for longer is the only way you'll achiever that. If not, I'd ditch my long runs (three hours this Saturday) in favour of heavy lifting and a couple of HIIT sessions, then I'd have a lot more time to myself!

    Wow, you must eat a LOT if you are eating back the calories from that amount of cardio! I'm jealous!! :-) I say if you enjoy it and you're not injuring yourself in any way, then go for it!

    I'd say that if it makes you feel good & improves your health, and most importantly, if you actually enjoy it - go for it.
    I used to do an hour + of cardio every time I went to the gym, but after a few months I started feeling that I don't want to go to the gym anymore, because it's too hard and too time consuming. So now I'm back to 30-45 minutes & enjoying working out again. (:

    I have been doing 1.5 - 2 hours 5 days a week and it hasn't done me any harm.

    I personaly do 2 hours of cardio 4 times a week the other 3 days I do 1 hour of cardio....I also do strength training 5 times a week...that being said I believe the fear is that to much cardio causes you to "burn muscle" as long as you are doing your strength training 3 days a week I would say you are fine.....marathon training is way more than the amount of cardio you are doing and marathon runners are alive and well.....here's an interesting article , that may help you...

    i watched a show the other day and the bloke lost like 11 stones in one year. he did it by eating good and exercising 4 hours a day, mainly cardio. worked for him so you should be okay. :) just make sure your joints don't suffer too much, and that you're not over doing it. good luck!

    As long as you are eating back your calories I don't see why it would be a problem. But make sure you have rest days too or you might overwork your body. Also, Dexter is awesome :)

    I'm not an expert by any means - but I don't think it hurts you at all. For myself, thoguh, I have noticed that if I work out longer than an hour a day, my weight loss will plateau. I lose the most at about 30 to 60 a day, and I do strength training and cardio on alternating days.

    The only thing that keeps me from doing this, is non-exercise obligations.

    You're getting ST, you're doing it by different modes of transportation. Sounds good to me as long as you're allowing yourself proper rest.

    When are you entering your frist triathlon?

    Or if you were really feeling good you could join these nutcases:

    That much cardio is a waste of time if you are doing it it to help lose weight or just become physically fit.

    However if you want to be an endurance athlete, that is exactly what you need to do. High volume is the most effective type of training for this.

    So it depends on what you are trying to achieve that should determine how much cardio you should be doing.

    This..... I'm a long distance runner and do triathlons and mountain climbing. It is in no way harmful if you are sensible, know you limits, build up endurance and fuel yourself correctly. Longest run, non competition level, was 4 hours for me.
