It was curiosity at first sight. And love at first workout.
That’s the response I had after first seeing – and then trying out – the Cybex Arc Trainer at a client’s fitness center last year.
I was so impressed with the Cybex Arc Trainer that I decided to purchase one for my home gym.
After a false start with the home version of the machine (the 350A Home model, which I didn’t like – more about that after the jump), I upgraded to the top of the line Cybex Arc Trainer 630A (now the 750AT) – the same commercial grade equipment at the gym.
The Cybex Arc Trainer 630A is far and away my favorite cardio fitness equipment. Here’s my assessment of the Cybex Arc Trainer – and why I think it is the best elliptical trainer / cross trainer on the market.
What I Like:
- A great workout but not hard on the joints: The unique ”reverse arc” motion moves your legs in a biomechanically correct pathway – reducing stress at your knee. The arc never places your toe behind your knee (when your toe moves behind your knee there is significantly more stress applied to your knee joint).
- Adjustable stride height: This is where the Cybex Arc Trainer really shines. With other elliptical trainers, your stride height remains fixed in the same position. With the Cybex Arc Trainer, the stride height – how high your knees come up as you stride – is adjustable. As Cybex describes: “At the lower incline levels, the ‘glide’ is a cross country skier. In the mid-range levels, the motion is a ’stride’ (like an elliptical except with proper positioning). At the high levels, the ‘climb’ of a stepper or climber.” I like the variety this provides in my workouts, both physical and mental. Especially during the “Hill Profile” programmed workout.
- Natural movement of legs and arms: With the Arc Trainer, as your right leg moves forward, your right arm moves forward at the same time. This allows you to always maintain optimal posture during exercise, which virtually eliminates stress on your back. And it tracks similarly to the way your legs and arms move same side when running (which I prefer). With other cross trainers, your arms and legs move in opposite directions.
- Display: The digital display is easy to use and easy to read. The upper display shows distance, calories, calories/hour, METs, watts, strides per minute and heart rate; lower display shows time, incline and resistance level.
- Solid feel: everything about the fit and finish of the Cybex Arc Trainer is solid and well put together.
- Smooth ride: The Cybex Arc Trainer is the BMW of elliptical trainers.
- Self powered: does not require a power cord (one less tangle of power cord = simplicity).
- Wide cup holder: Accommodates even my relatively wide CamelBak bottle.
- Cybex employees: The employees I spoke with on the phone were helpful, friendly and professional. Particularly Bill Domineau, Vice President of Customer Service, who enabled me to do a paid upgrade from the 350A Home which I hated, to the 630A which I love. Dear Cybex, you have a winner with Bill!
What Could Be Better:
- Tray: the “magazine rack” lacks a good place to put your iPod, the shelf is too narrow. In an otherwise well designed high-end machine, this is an oversight, given that most of users have MP3 players.
- No cool down function: The Cybex Arc Trainer doesn’t have a cool down function. You can get around this by starting another 10 minute workout in Manual program, with low level and low incline. But on a high-end machine, I’d expect the work out programs would have the option for a cool down.
- Safety of children and pets: the way the hinged parts move, you MUST be 100% sure that children and pets are kept out of the room while you workout. This is not optional, this is otherwise potentially extremely dangerous. A child or pet investigating the machine while you exercise could be seriously injured or worse by the force of the moving parts near the base of the machine. While there is a warning sticker on the machine, I’d like to see Cybex engineers design a machine that has more safety space between the base and the moving parts.
After the jump:
- My mini-review of the Cybex Arc Trainer 350A Home
So what do YOU think? What’s your favorite exercise equipment? What do you like best about it?
My Mini-Review of the Cybex Arc Trainer 350A Home:
The 350A Home (now 360A Home) version of the Arc Trainer machine is not the same as the commercial version. Not even close. It’s sort of like the difference between a Chevy and a BMW. Both are cars and will get from point A to point B. But the BMW has the far superior ride.
While they look similar, there are many key differences between the home and commercial versions. At the time I purchased, Cybex marketing materials did not adequately explain the differences. So I’ll detail the differences here:
What I Didn’t Like:
- The control panel buttons look and feel cheap, like they are from a science fair kit.
- Resistance levels go from 1-20, but at maximum setting of 20, the resistance is merely 50% of the 630A model.
- Incline level of 1-10 on the 350A Home does not equate to incline level of 1-10 on the 630A (approximately 70% less stride height – this is a BIG difference, and IMO makes the 350A a non-starter.)
- The arms of the machine feel too far forward, causing you to lean in to reach them and taking you outside of the ideal position Cybex describes with the 630A.
- Not as smooth as the 630A.
- While doing a programmed workout that includes changes to incline, the display doesn’t show the incline number changing as the inclines changes (unlike the 630A model).
- Cupholder is too small.
- The unit I received came with backlevel firmware, and the wireless heartrate monitor did not work correctly.
- The unit I received had a backlevel manual.
- Set up issues: the arm bolt wouldn’t fit as intended, and as a result a service call by a technician was required; there was a loud vibration inside the motor housing, that required yet another service call by a technician.
What I liked:
- The tray is well-suited to place an iPod on it.
- Functional
- Less expensive than the 630A.
- Design looks good.
- Despite the things I didn’t like, it is still better than a standard elliptical trainer.
- While I’d prefer to never have to meet a service technician, the independent service technicians I met with outstanding. A+

Thanks for the review. I think, asfter reading your review that I owuld not purchase the home version or 350A as I had considered.
Not sure if the 650 price range is worth it though…:(
@Deb, thanks for stopping by and reading my blog.
I’d encourage you to find a local store that sells the 350A and try it out for yourself. Everyone is different, and perhaps it just wasn’t what I like, but could be what you and others like. It’s a good machine, just not the same as the 650, and you just have to know what the differences are going into the purchase.
And I’ve got to tell you: the 650 is more than worth the extra price! I am very happy with it.
At cap maison we have a few gim equipment and my cybex arc trainer model;425a is not working .serial number co4-17425a9044n2497 . There is no power on the display but power goes to the unit.
Any assistance will be greatley appreciated
Thank You

@popo – you’d have to contact Cybex about that! (But if you want to fly me to St. Lucia, I’d be glad to provide business consulting or coaching!)
Very helpful review. I would have got the 360a before I read your review. But on the 610a at my gym, I only get a good workout at 7+ incline. If you had to compare the 360a to the commercial models, what percentage of incline do you think you can achieve?
Also, do you know the difference between the 610a and the 630a? I think right now I’m leaning toward getting a used 610a – that is, assuming the 610a is as high quailty as the 630a. Maybe the 630 is the same as 610 but newer? Or the legs-only version? help?

Comparing the incline for the 350A Home with the incline for the 630a commercial, here is what I found: Incline level of 1-10 on the 350A Home does not equate to incline level of 1-10 on the 630A (approximately 70% less stride height – this is a BIG difference, and IMO makes the 350A a non-starter.)
As far as comparisons between 610a and 630a. I think your best bet is to call Cybex and ask them, they should be a better source of info on that.
I purchased a 350A about 12 months ago but the retail store replaced it for free with a 360A 3 months into the purchase when a piece within the main mechanical unit broke. I’ve had the 360A for about 9 months now and I like it a lot. I have a treadmill and switch between the two. I’m a big guy and the 360A still works well with my extra weight. Its mostly steel (very little plastic) which is good and a bit unusual in a home unit. But the two foot pads have both recently cracked. They still work but I will now seek to replace them. Not sure why these foot pedals are plastic if the majority of the devise which takes the weight & stress is metal. But all-in-all, I recommend the 360A.
