This is so confusing......

How is there that big of a difference between my watch and the machine? Which one do I go by? Yes I have my weight entered accurately on both. 🤷🏽‍♀️

    I’d go with your watch. My watch has been accurate for me.

    Michael Phelps would burn 700 calories in an hour. Unless you're doing Olympic style effort, I'd go with the watch.
    Not to mention, machines HARDLY ever get calibrated once a month like they are supposed to.

    I'd go with the watch.The 223, not the 262 - but then I wouldn't be synced to MFP, I'd just enter it manually.

    704 kcal for 28 minutes is HIGHLY unlikely. Your watch estimate looks a lot more realistic to me.

    I agree. Maybe the machine is broken.

    All of the above and show your snap to the gym's manager

    My TM assumes I weigh 200 lbs. I think. Walking at 4 mph, it says I burn 600-700 calories per hour, depending on the incline (usually between 1-5%). Running at 6 mph it will say I burn 1000 calories an hour. I think it overcompensates for the incline. OTOH, your watch may be undercompensating for the incline if it isn't enough to cause your HR to go up. In any case, I'd go by the watch, not the machine.

    Why wouldn’t you be synced to MFP? I’m asking because mine is. Sometimes I wonder if some of the calories I’m earning count?

    Nobody is burning 700+ calories in under 30 minutes...you'd be hard pressed to do it in 60. Machines in the gym get used by tons of people...they break...calibration can go off, etc.

    I'll take this one, as a theoretical question, since I'm not OP. I'm not synched because my good brand/model fitness tracker - one that's accurate for others - is wildly far off for me**. If I synched it to MFP, it would cause more problems than it would solve. This is a rare thing, but statistical outliers exist, and I seem to be one, for some reason. 🤷‍♀️

    If it were close, I'd synch it. I do use it for exercise calorie estimates when I don't have a more accurate source, because I don't have a good alternative . . . and those are a small enough fraction of my daily calories that any discrepancy gets lost in the noise of overall estimating.

    ** Both MFP and my tracker think I need around 25-30% fewer calories than 5 years of logging experience tells me I actually need, to maintain my weight. I'm going to maintain my weight, not lose at a silly-fast rate just because some estimates are wrong, y'know?

    Everyone seems to worry that their tracker will OVERestimate their calorie burn. I'm here to tell you that it can UNDERestimate it, too, potentially. For most people, their trackers are close. Your results over many weeks will give you a hint whether it's accurate for you. It's likely to be the best starting estimate you could come up with.

    Machine readings are notoriously high and generally inaccurate.

    I’m pretty pleased with the readings I get on my Apple Watch, and feel they are pretty accurate.

    Even the brand new what-do-ya-call-em (brain fart) sitting down bike I have does the same thing, and I’m the only person who’s ever used it. It came straight out of the box, is a fairly high end piece of equipment, and I’ve carefully entered age, weight, height.

    I think it’s to manufacturers and gyms benefit to make us feel like we’re getting our money’s worth. That’s my thought, for what it’s worth.

    In addition to what everyone else is saying, is it possible that the machine is tracking kilojoule and not kilocalories / calories? 704 kilojoules would be 168.26 calories. While still off, it's a bit more realistic. The elliptical machine that my parents have tracks energy in kilojoules, but I haven't seen many others that do.

    Thank you so much! @AnnPT77 I never thought of it that way.
