How many calories does an hour at the gym burn?

If I do 60% cardio (treadmill / cross-trainer / bike) & 40% weight machines. I want to make sure I don't over-estimate, but I thought 250 calories would be about right?

    I add all exercise as cardio but I amend the number of calories depending on the exercise. I allow 100% for steady state like jogging or elliptical, 75% for circuit class and 50% for weights.

    Totally depends on your stats (eg weight), fitness level, how much effort you're putting in (eg jogging vs sprint intervals).

    Impossible for us to estimate that for you. Too many variables, not enough info.

    I'm 61 kg & do 15 minutes treadmill - half running at 9.5km/hr & half fast walking at 5.5km/hr. 10 minutes cross-trainer, 10 minutes bike, 8 minutes recumbant bike. Rest is weights.

    I recommend the elliptical! I do 45 minutes a day and I've lost 16 pounds in 15 days!

    have you tried putting that into your MFP diary?

    Personally I only enter in my cardio exercise. I do not add strength training. That way, if MFP or the cardio machine overestimates the amount of calories I burn (which it often does), and I eat back some or all of those calories, well at least I don't eat back my strength training calories.

    No way unless you pretty much quit eating also.

    Still not enough data. Your height, weight, age, gender, hormones.....way too many factors to get an "accurate" number.

    Even if we know the speed, the weight, etc....just how hard was that workout for you?

    Assume 0 calories burned from weightlifting. I know it sounds stupid, and it feels like you're burning a lot, but it's mostly just CNS stress.

    How do calorie burns differ with height, age, gender and hormones?

    For strength training I found this formula and it seems to be working. (weight) x (minutes spent lifting) x (0.021-0.029 depending on your intensity) so for me yesterday I did back and bis for 30 minutes, I weigh 140 and I gave about 70% effort 140x30=4200x0.023 =96.6 calories burned.

    do runtastic apps squat/push-up/sit-up overestimate calories burnt?

    For the cardio, you can improve your estimates by using the machine's calorie burn (not perfect, probably better than MFP's, especially if the machine lets you specific age/weight) or a heart rate monitor (not hugely expensive, just get a decent quality one with few features - but including custom calorie burn). But heart rate monitor will over-rate weight lifting, IME. (I don't have a better formula.)

    Agreed with 2 posters above. Just use the calorie count on your machine, and don't add anything for weight training.

    It is possible to make a guesstimate, but I would have little confidence in it as not enough information is provided. the three things you need to know are weight, duration and intensity. You are on the way to providing the first two, but without knowing how hard you are working then its of little use.

    Most people pit 1 or zero calories for resistance work.

    Well, that part is about 65 calories. So call it 240-ish calories for the hour as an upper limit.
