They look alike, but the Arc Trainer and the elliptical move differently. Here's the real difference — and how cross trainers and AMTs compare too.

1. The Short Answer
An elliptical moves your feet in an oval and usually has a fixed or limited incline. An Arc Trainer moves your feet along a flatter arc and lets you change the incline to shift between striding, elliptical-style and climbing motions. The Arc Trainer is designed to put less forward stress on the knees and tends to work the glutes harder; the elliptical is more familiar, more widely available and usually cheaper.
2. Side-by-Side Comparison
| Feature | Arc Trainer | Elliptical |
|---|---|---|
| Foot path | Arc-shaped | Oval |
| Impact | Low | Low |
| Knee travel | Designed to minimize forward knee travel | Knees can travel further forward |
| Incline | Adjustable on most commercial models | Often fixed; some models adjust ramp or stride |
| Main muscle emphasis | Glutes, quads, hamstrings | Quads, glutes, calves |
| Upper body | Total body models only | Most models with moving arms |
| Home availability | Limited, mostly premium models | Very wide, all price points |
| Typical price | Higher | Wide range, lower entry point |
3. Which Is Easier on the Knees?
Both machines are low-impact, because your feet stay on the pedals the whole time. The difference is in the angle of the knee. Cybex designed the Arc Trainer's motion to keep the knee from drifting forward past the toes, which many users find more comfortable than an elliptical. If ellipticals bother your knees, the Arc Trainer is well worth trying.
4. Which Burns More Calories?
Calorie burn depends mostly on how hard you work, not which machine you choose. That said, the Arc Trainer's adjustable incline and resistance make it easy to push into a very high-intensity effort, especially in climbing mode, while staying low-impact. On either machine, intervals and higher resistance burn more than a steady, easy pace.

"Cross trainer" usually just means an elliptical with moving arm handles, so the comparison is the same as with an elliptical. Life Fitness, for example, calls its ellipticals cross-trainers. Elliptical cross trainer vs. elliptical is a naming difference rather than a different machine: a cross trainer has moving arms for a total-body workout, while some ellipticals have fixed handles only.

The adaptive motion trainer, or AMT, is Precor's take on hybrid cardio. Instead of a fixed path, the AMT lets your stride adapt as you move, from a short step to a long run-like stride. Compared with an Arc Trainer, the AMT offers more freedom of movement; compared with an elliptical, it feels less guided. The Arc Trainer sits in between: a fixed path, but with adjustable incline.

- Choose an elliptical for a familiar motion, a lower price and more home options
- Choose a cross trainer (elliptical with arms) for a simple total-body workout
- Choose an AMT if you want a stride that adapts to you
Final Thoughts
Arc Trainer vs. elliptical isn't about which is better overall — it's about which motion suits your body. The Arc Trainer is designed to be easier on the knees, works the glutes harder and adds variety through adjustable incline. The elliptical is familiar, affordable and widely available. Try both if you can, and pick the one you'll actually enjoy using consistently.
