What Is an Elliptical Trainer? Motion, Muscles & Benefits

An elliptical trainer is a stationary exercise machine that lets you walk, jog, or climb stairs without your feet ever leaving the pedals. Because your feet stay planted throughout the motion, the machine eliminates the repeated impact of hitting the ground, making it one of the most joint-friendly cardio options in any gym. Precor introduced the first commercial elliptical in 1995, and the machines have since become a staple of both commercial gyms and home setups.

How the Motion Works

The pedals on an elliptical move in an oval (elliptical) path that combines two movement patterns at once. The forward-and-back glide simulates walking or jogging, while the up-and-down component mimics a stair climber. Most models also have moving handlebars linked to the pedals, so your arms push and pull in rhythm with your legs. The result is a smooth, continuous stride that engages both your upper and lower body simultaneously.

The key mechanical advantage is what exercise physiologists call reduced “ground reaction force.” When you run on pavement or a treadmill, each footstrike sends impact through your knees, hips, and lower back. On an elliptical, your feet travel with the pedals rather than striking a surface, so that repeated shock is virtually eliminated. This makes the machine especially useful if you’re recovering from a joint injury, dealing with arthritis, or simply looking for a way to train hard without accumulating impact stress.

Muscles Used

The lower body does the bulk of the work. Your quadriceps and glutes drive the pedals downward, while your hamstrings and hip flexors pull them back up and around. Calves engage to stabilize your foot on the pedal throughout the stride. If you increase the incline (available on many models), glute and hamstring involvement increases, similar to walking uphill.

The moving handlebars add your chest, upper back, and arms to the equation. Pushing the handles forward recruits your chest and triceps; pulling them back targets your upper back and biceps. That said, it’s easy to let your legs do all the real work while your hands just rest on the handles. Actively pushing and pulling makes the difference between a lower-body workout and a genuine full-body session.

One common pitfall: because the machine controls your path of motion, you can fall into a passive glide without truly engaging your leg muscles. To counter this, focus on pressing your legs down and back, then pulling them up and forward in a deliberate cycling pattern rather than just letting momentum carry you.

Cardiovascular and Calorie Benefits

Elliptical training builds aerobic fitness at rates comparable to running. A study published in the International Journal of Exercise Science tracked runners who switched to elliptical-only training for three weeks. Their aerobic capacity declined by just 1.5%, compared to 0.8% for those who kept running. Statistically, the difference between the two groups was not significant. A group that stopped exercising entirely, by contrast, lost 4.8% of their fitness in the same period. In practical terms, the elliptical maintains cardiovascular conditioning nearly as well as running does.

Calorie burn depends on how hard you push. At a light effort, elliptical exercise rates around 3 to 4 METs (a standard measure of energy expenditure), roughly equivalent to a casual walk. Moderate effort bumps that to 5 to 5.5 METs, comparable to a brisk walk or easy jog. Vigorous elliptical work reaches 8 to 9 METs, putting it on par with running at a moderate pace. For a 155-pound person, vigorous elliptical training burns roughly 450 to 500 calories per hour.

Front Drive vs. Rear Drive

The flywheel location determines how the machine feels underfoot, and this is the single biggest design difference between models.

  • Front-drive machines place the flywheel at the front and produce a flatter, more natural stride that feels like walking or running uphill. They tend to offer longer stride lengths (up to about 50 cm) and higher weight capacities because your weight is distributed across rear rollers on rails. The tradeoff is size: front-drive models take up more floor space and have more moving parts, which means more potential maintenance.
  • Rear-drive machines place the flywheel behind you, creating a slightly more circular, “hopping” motion that some describe as walking downhill. They’re generally more compact and simpler in design, making them popular for home gyms where space is tight. Maintenance needs are lower because there are fewer components.

If you’re tall, a front-drive model is typically more comfortable because of the longer stride. If floor space is your main constraint, rear-drive models fit into tighter rooms more easily.

Resistance Types

Most home and commercial ellipticals use magnetic resistance. Magnets positioned near a spinning flywheel create drag that you adjust with a button or dial. The motion feels smooth and consistent, and the machine runs quietly, which matters in apartments or shared spaces.

Some models use air resistance instead, where a fan-style flywheel generates drag proportional to how hard you push. The harder you go, the more resistance you feel, with no need to press a button. This creates a very responsive, dynamic workout, but air-resistance machines are noticeably louder and can push air around the room. They’re more common in commercial gym settings than in homes.

Choosing the Right Stride Length

Stride length is the distance each pedal travels in one full revolution, and getting it wrong makes the motion feel cramped or overextended. The right length depends mainly on your height:

  • Under 5’0″: 11 to 14 inches
  • 5’0″ to 5’3″: 14 to 16 inches
  • 5’4″ to 5’8″: 16 to 20 inches
  • 5’9″ to 6’0″: 18 to 20 inches
  • Over 6’0″: 20 inches or more

Many mid-range and high-end machines offer adjustable stride lengths, which is especially useful if multiple people in a household share the same machine. Budget models often have a fixed stride around 18 inches, which works for average-height users but can feel awkward at the extremes.

Form Tips That Actually Matter

Stand upright with your shoulders back and your core engaged. Leaning forward and hunching over the console is the most common form mistake, and it shifts stress into your lower back while reducing how much work your legs and glutes actually do.

Place your feet so your heels rest on the pedals with your toes pointing slightly outward. This position gives you a full range of motion and keeps unnecessary strain off your ankles and knees. Avoid rising onto your toes, which overloads your calves and can cause numbness in your feet during longer sessions.

If the machine has moving handlebars, grip them lightly and use your arms with intention. If it only has fixed center handles, use them for balance but avoid leaning your weight into them, as that reduces calorie burn and lets your legs coast.
