An elliptical machine gives you a full-body cardio workout while placing significantly less stress on your joints than running. It engages muscles from your shoulders to your calves, builds aerobic fitness, and can improve metabolic health markers like blood sugar. Because your feet never leave the pedals, it’s one of the gentlest ways to get a high-effort workout.
Upper and Lower Body Muscle Activation
The elliptical is unusual among cardio machines because it works both your upper and lower body simultaneously. EMG studies measuring electrical activity in muscles found that the elliptical activates the biceps, triceps, chest, and upper back significantly more than either a treadmill or a stationary bike. That makes sense: you’re actively pushing and pulling the handles through a full range of motion with every stride, not just resting your hands on a bar.
For your lower body, the picture is more nuanced. The elliptical fires the front of your thighs (the rectus femoris) more than cycling does, and it demands a good deal from your quads and calves throughout the motion. However, a treadmill still activates the glutes and calves more than the elliptical, largely because walking and running involve pushing off the ground with each step. If building your glutes is a priority, the elliptical alone won’t match running or weighted exercises, but it provides steady engagement across the entire leg.
One simple trick changes the muscle emphasis entirely: pedaling backward. Reversing your stride shifts the workload from your glutes and hamstrings toward your calves and quadriceps. Alternating directions during a session lets you distribute effort more evenly across your leg muscles and reduce fatigue in any single group.
Cardiovascular Fitness
The elliptical builds aerobic capacity in much the same way running does. A study published in the International Journal of Exercise Science tested whether elliptical training could maintain the VO2 max gains people made from a running program. After three weeks, runners who switched to the elliptical saw only a 1.5% decline in VO2 max, nearly identical to the 0.8% decline in the group that kept running. Meanwhile, the group that stopped training entirely lost 4.8% of their aerobic fitness. Statistically, there was no meaningful difference between the elliptical and running groups.
What this tells you is practical: if you’re a runner dealing with a nagging injury, or you simply prefer the elliptical, you’re not sacrificing cardiovascular gains. Your heart and lungs don’t care whether your feet are hitting pavement or gliding on pedals. What matters is sustained effort at a challenging intensity.
Joint Stress and Injury Prevention
This is where the elliptical truly stands apart. Research comparing the forces on your lower body during elliptical use versus walking found that the loading rates around heel strike are all smaller on the elliptical. The vertical force pushing up through your legs during early stance is lower than the ground reaction force you experience walking on a hard surface.
Your hips and knees do still work hard on an elliptical. Peak hip flexion and knee extension angles are actually greater than during walking, meaning your joints move through a larger range of motion. But the way force is applied is smoother and more gradual, without the sharp impact spike that comes from your foot striking the ground. For anyone with knee arthritis, shin splints, stress fractures, or joint pain that flares with running, the elliptical lets you train at high intensities without that repeated impact loading.
Metabolic Health and Blood Sugar
High-intensity interval training on an elliptical can improve metabolic markers that matter for long-term health. A pilot study in the Journal of Physical Activity and Health put people with prediabetes and type 2 diabetes through a 12-week program of elliptical HIIT, three sessions per week. By the end, participants showed significant improvements in fasting blood glucose levels.
This matters because the elliptical’s low-impact nature makes it accessible to people who may struggle with other forms of intense exercise. If you’re carrying extra weight or managing diabetes, running intervals might feel punishing on your knees and ankles. The elliptical lets you push your heart rate into those higher training zones, where the metabolic benefits happen, without the joint consequences.
What the Elliptical Won’t Do
One notable gap is bone density. Your bones strengthen in response to impact, the literal force of your feet striking a hard surface. Because the elliptical eliminates that impact, it doesn’t provide the same stimulus for bone growth that running or jumping does. If you’re at risk for osteoporosis, relying solely on an elliptical for exercise means you’re missing one of the key triggers for maintaining strong bones. Adding some walking, light jogging, or resistance training alongside your elliptical work fills that gap.
The elliptical also won’t build significant muscle mass. It strengthens and tones the muscles it activates, but the resistance level is too low and the motion too repetitive to drive the kind of progressive overload that builds size. Think of it as muscular endurance training rather than strength training.
Balance and Functional Movement
Standing upright on moving pedals while coordinating arm and leg movements challenges your balance more than you might expect. Your body has to constantly stabilize your head, arms, and trunk over a shifting base of support, which engages the vestibular and proprioceptive systems that govern your sense of balance and spatial awareness.
Research on children recovering from acquired brain injuries found that 24 sessions on a motor-assisted elliptical produced measurable improvements in balance scores, with one participant improving dynamic balance items by 43%. While this was a rehabilitation population, the underlying mechanism applies broadly: the elliptical trains your body to maintain coordinated, upright movement, which translates to better stability in daily life. For older adults concerned about fall risk, this is a meaningful secondary benefit on top of the cardiovascular workout.
Getting the Most From Your Elliptical Workout
To maximize what the elliptical does for your body, a few adjustments matter. First, actually use the handles with effort. Letting your arms go limp while your legs do all the work eliminates half the muscle engagement the machine is designed to provide. Push and pull deliberately.
Second, vary your resistance and speed. Steady-state workouts at moderate effort are fine for building a cardio base, but interval sessions where you alternate between high and low intensity deliver greater improvements in aerobic capacity and metabolic health. A simple structure of 30 seconds hard, 60 seconds easy, repeated for 20 minutes, is enough to push into those higher training zones.
Third, change direction. Spending a few minutes pedaling backward during each session shifts the muscle activation pattern and helps balance out the strength demands across your quads, hamstrings, glutes, and calves. Most people never touch this feature, but it’s one of the elliptical’s genuine advantages over a treadmill or bike.
