    Preferences? I read reports that stress on the knees does not just come from impact. Even though both trainers do not cause high impact, the motion of the AMT causes more knee stress. This is an interesting study, but it was funded by Cybex.

    I suspect the problem is the AMT adapts to any motion and allows you to add significant resistance. If you are hitting the limits on the forward/backwards motion with your knees bent, you probably are causing problems.

    My 24hr fit has a whole row of AMT's. I don't see that.

    I tend to see more people using it at a very low resistance and talking on their phones. icon_twisted.gif

    Interesting information. I have used both the ARC and AMT but not the Octane machines. Octane has improved over the traditional elliptical with a variable stride, but so have other companies. I haven't heard of others who have used Octane specifically, but many overwhelmingly prefer the ARC to both the AMT and other variable stride ellipticals.

    Wondering if preferences and issues result from different people's geometry as well as the usage. For example, will someone's preference be impacted if they use the machines for really high intensity workouts versus using them while talking or reading the paper.

    Presuming all three machines allow you to crouch down and bend at the knees, you're gonna feel it the next day. I've discovered that if you don't keep your feet parallel to each other, you will also screw your knees up.

    This "study" is missing a few details.

    In the end, Precor has the best iPod/Nike+ integration. So, screw Cybex.

    The Arc Trainer is what I use regularly in the gym. In one 1-hour workout I can burn approx 1,100 calories without incurring any injury.

    Well, I live above a 24hr fitness super sport with a row of about 12 AMT's, so I did some experiments, not to be confused with actual expertise. I think I have a good understanding about how the test was run. They most likely tested the AMT as it is advertised and got the arms involved with the hand grips, pushing the feet forwards and backwards. If my understanding is correct, that isn't good.

    My knees are happy if my feet are parallel and I am able to keep constant pressure evenly on both knees, keeping things in place.

    The AMT has the levers for your hands, leading you to believe its a good idea to start moving your feet forwards and backwards vigorously. This leads to a situation where I start shifting my body weight from side to side, causing an uneven distribution of weight on my knees. I especially hurt if I let the pedals get to the same height, then start shifting them frontwards and backwards. My bodyweight gets unbalanced.

    Its those handlebars that screw your knees up, I guess.

    But, I still think it may be one of the most effective cardio options at high resistance. Just focus on moving your feet in the vertical axis for the sake of your knees.

    I don't have a Arc Trainer but I love our AMT. I get terrible pain in my knees when I run so this machine helped give me a nice alternative to the treadmill. I still haven't learned how to pause the damn thing though. I usually stop at 30 minutes and walk to get a drink of water. By time I get back the machine has reset. *shakes fist* I'll figure it out one of these days...

    AMT control panels have a rechargeable battery.
    If it's "self powered", you have 30 seconds.

    If you have the external power adapter, you can use "Max Pause Time" of up to 2 minutes. See page 76 of the repair manual PDF.

    You stud! 30 minutes above level 10 and I'll need a nap!

    They're amazing machines. I'd own one except its cheaper to just live near a gym that has a whole row of them.

    And, it has a bottle holder. Why you no have water bottle before you climb on?

    Whoa, I don't quite get it up to 15. I tried 15 today and it was considerably more challenging than 10. I may try a half hour tomorrow at 15 and see what i can do. Im already exhausted thinking about it.

    Mine doesn't have one. It does have a small cubby you can put your key/wallet in. I usually dont pack water with me while im on it because i'm more tempted to stop and take a swig. So I just stop at 30 mins, walk back to water fountain and do another 30.

    I very much prefer the ARC Trainer to the AMT. The study in the OP was funded by Cybex, but indicated significantly less knee stress with the ARC Trainer. I haven't seen anything to rebut that.

    Love the Precor AMT. Would be nice to own one if they didn't cost $8K

    I've used three versions of the ARC trainer since 2008. I think they're great machines. I've used the Precor AMT Trainer, too.

    I like the greater stride that the Precor machine offers, but I do not feel the resistence is as challenging as the ARC trainer.

    When using either machine, I do alternate the position of my feet to prevent any discomfort caused by keeping them in the same spot for the entire duration. I also limit my cardio on these machines so that I do not use either one more than twice a week, unless it's just for a short warm-up.

    As for knee stress, posture is very important. I see so many people on these machines, and on the stair climbers hunched over, leaning forward with their knees in front of their feet. Although I did not see anything mentioned in the referenced study, I'm certain this is a significant factor on stress and fatigue.

    My gym has 2 rows of cybex arcs...
    if your knees hurt after you use the machine...
    A) You set the incline too high
    B) Resistance setting is too high

    Personally i don't like the Arc..it burns too much fat from my glutes...
    15 minutes...incline 7...resistance...20...2 days a week..thats it...
    I am a stair climber man..
    Love what it does for my glutes...!!!icon_biggrin.gif
