Arc Trainer vs. Elliptical: Which Cardio Machine Is Better for Your Fitness Goals?
For readers comparing cardio machines, the useful question is often not which device is โbetterโ in the abstract, but which one is easier to use consistently and safely. In that sense, the main advantage of either option may be adherence: a machine that feels comfortable, fits your space and matches your preferences is more likely to become part of a regular routine.
It is also worth separating what a machine can do from what the evidence can prove. Low-impact cardio can support fitness, but many claims about one machine burning more fat, building more muscle, or being gentler on joints are best treated as plausible, not universal. Individual biomechanics, workout settings and prior injury history can change how the same movement feels from person to person.
That means the โbestโ choice may depend on the training goal you can realistically repeat. A higher-effort machine can be useful for interval-style sessions, while a more comfortable, adjustable option may make steady-state cardio or recovery workouts easier to sustain. The practical trade-off is simple: a machine that looks more specialized may offer a stronger training feel, but a more familiar one may deliver better long-term consistency.
For home use, cost, footprint and maintenance matter as much as workout features. If a device is too expensive, bulky or awkward to use, its theoretical benefits matter less. A sensible approach is to treat these machines as tools for movement variety, then choose the one that supports your schedule, joints and motivation with the least friction.
The arc trainer and elliptical are two popular choices when it comes to cardio machines. Both offer effective, low-impact workouts that can help you build endurance, boost heart health, and protect your joints.
But while they look similar at first glance, there are key differences when it comes to picking the arc trainer versus the elliptical. Here, experts break down everything you need to know to decide which one is the right fit for your fitness goals and health needs.
What is an arc trainer?
An arc trainer is a piece of gym equipment designed to simulate the movement patterns of walking or running, according to Josh York, CPT, certified personal trainer and founder and CEO of GYMGUYZ.
The machine has handlebars and foot pedals that move back and forth in an arc-shaped motion. This arc movement is designed to reduce stress on your joints while still working the major muscle groups in your legs and delivering a challenging cardiovascular and strength-building workout, York says.
Some machines have fixed handlebars to concentrate the effort in your lower body, while others have moving handlebars for a total-body workout.
Arc trainers are also typically adjustable, allowing you to change the incline and resistance levels to suit different fitness goals like fat loss or endurance training.
What is an elliptical machine?
An elliptical machine is another type of low-impact cardio machine with handlebars and foot pedals that combines the motions of walking, running, and stair climbing into one, York says. While the movement looks similar to that of an arc trainer, the key difference is that elliptical foot pedals move back and forth in a circular motion.
Most ellipticalsโ handles move in unison with the foot pedals for a full-body workout, per Harvard Health Publishing, although some have fixed handles to focus the effort in your lower body.
Most ellipticals also offer adjustable resistance and incline so you can vary the intensity of your workout for different objectives, like hitting a target heart rate or interval training.

Similarities between arc trainers and elliptical machines
Both the arc trainer and elliptical share several features that make them popular choices for cardiovascular workouts. Hereโs what they have in common:
- Theyโre low-impact: Both machines place less stress on your joints than higher-impact alternatives like running, says certified personal trainer Nate Feliciano CFSC, CES, owner of Studio 16 and director of personal training for Exhale Spa. This can also help reduce the potential for injury, York says.
- They build endurance: A session on the arc trainer or elliptical ups your heart rate, breathing, and muscle use. Over time, this trains your heart, lungs, and muscles to work more efficiently so you can work harder for longer, according to the American Heart Association.
- Theyโre versatile: โNo matter where you are with your fitness level, these machines have your back,โ York says. โYou can dial up the intensity or keep it light with customizable resistance to meet or exceed your goals at the pace that fits your needs.โ
Differences between arc trainers and ellipticals
While the two machines may look alike, there are some key differences to keep in mind:
- Their movement patterns: An arc trainerโunsurprisinglyโmoves your legs in an arc-shaped pattern, which is designed to mimic the natural movement of running, Feliciano says. Ellipticals, on the other hand, move in a circular motion.
- Their impact on your joints: Arc trainers are gentler on your knee and hip joints because they more closely mimic natural leg movement. While ellipticals are also low-impact, their circular motion may be less comfortable for those with knee or joint issues, per a March 2010 study in The Journal of Strength and Conditioning Research.
- Theyโre intensity: Both machines provide an effective cardiovascular workout, but arc trainers are particularly effective for higher-intensity interval and strength training, York says. Ellipticals are better suited for weight loss, cardiovascular conditioning, physical rehabilitation, and recovery days.
- They target different muscles: The motion of an arc trainer engages your glutes, hamstrings, and quads more effectively than an elliptical, York says. Ellipticals tend to place more emphasis on your calves, quads, and arms.
- Their prices: Arc trainers are typically the more expensive option, Feliciano says, sometimes running you upward of $7,000. In contrast, there are some more affordable elliptical options, ranging from $300 to $3,000.
Arc trainers vs. ellipticals: Which is right for you?
Choosing between an arc trainer and an elliptical depends on your fitness goals, health status, and personal preferences.
โAsk yourself if you want more muscle engagement or a full-body challenge during your workout,โ York says. โIf youโre zeroing in on your lower body, go with the arc trainer. A more complete, total-body workout would push you to the elliptical as your perfect match.โ
The arc trainer also has a slight edge if youโre looking for a higher-intensity workout, according to York. On the other hand, the elliptical offers a wide range of resistance, incline, and stride length settings so you can customize the machine to your preferences, whether thatโs steady-state cardio or interval training.
Your injury history and joint health are also factors. If you have ongoing lower-body joint issues or pain, then an arc trainer is likely the best option to minimize joint stress while still getting an effective workout, according to York.
Deciding between an arc training versus an elliptical can also depend on where you want to work out. If youโre shopping for your home gym, an elliptical is usually the most cost-effective and space-saving option, Feliciano says.
Still, there may not be a reason toย limit yourself if you can try both. โI recommend adding both into your training regimen,โ Feliciano says. โAdding a variety of movement patterns to your cardio programming can be beneficial.โ
Ultimately,ย it boils down to what feels best to you. โListen to your body first and foremost when selecting your workout method,โ York says.ย
