The calorie counter on your elliptical machine is almost certainly lying to you, and not by a small margin. Research published in the Journal of the American Medical Association found that cardiovascular machines systematically overestimate calorie burn, with some ellipticals inflating the figure by up to 42%. For anyone who has spent months or years trusting that number to guide their eating and training decisions, this is uncomfortable reading. It was certainly uncomfortable for me when a personal trainer first pointed at my screen and said, quietly but firmly, “Don’t trust that.”
Key takeaways
- Elliptical machines use flawed formulas that ignore your age, fitness level, and body composition—they assume a standard 150-pound person
- Gripping the handles lets your upper body do the work, offloading effort from your legs while the machine keeps counting phantom calories
- Heart rate and perceived exertion are far more honest indicators of real workout intensity than any display number
Why the calorie number on the screen is built on guesswork
Elliptical machines calculate calorie expenditure using a formula that assumes a standard body weight (often around 68kg or 150 pounds), a fixed metabolic rate, and a mechanical efficiency that doesn’t actually match how human bodies work. If you enter your weight at the start of a session, the machine adjusts slightly, but it still cannot account for your age, your fitness level, your body composition, or the specific way your metabolism responds to exercise. Two people of identical weight can burn dramatically different numbers of calories doing the same 30-minute session.
The handles complicate this further. Gripping the moving handlebars feels like you’re working harder, and in terms of perceived effort, you probably are. But your body is actually offloading work from your legs, which are the large muscle groups responsible for the majority of calorie burn during lower-body cardio. The machine doesn’t know you’re doing this. It keeps counting upward as though your legs are doing the same effort as someone who isn’t holding on. Over a 45-minute session, that discrepancy can easily account for 80 to 120 additional phantom calories on the display.
What actually happens when you grip those handles
Gripping the handlebars, especially tightly, shifts your centre of gravity and allows your upper body to partially drive the pedal motion, reducing the demand on your glutes, hamstrings, and quads. This matters for two reasons. First, your cardiovascular system works less hard, meaning your heart rate drops, your perceived exertion falls, and your actual energy output decreases. Second, and this is what trainers often emphasise, you lose the postural and core engagement that makes the elliptical genuinely useful beyond simple cardio.
There’s a proprioception argument here too. When you hold on, your body relies on the machine for balance cues rather than developing its own stability through the feet, ankles, and lower core. Over months of gripping, you may actually be training yourself out of balanced, independent movement, the opposite of what most people are hoping for from their fitness routine. Letting go, even partially, reactivates stabilising muscles that remain dormant when your hands are anchored to the frame.
That said, there are legitimate reasons to use the handles. If you have balance concerns, are returning from an injury, or are new to the machine, gripping while you find your footing is entirely sensible. The problem isn’t holding on occasionally, it’s the habit of gripping the entire time, every session, while trusting the calorie number to reflect genuine effort.
The metric you should be watching instead
Heart rate is a far more honest indicator of exercise intensity than any calorie figure a machine produces. Your heart doesn’t know what the display says, it responds to actual physiological demand. A wearable device that reads optical heart rate from your wrist (or a chest strap, which remains the gold standard for accuracy) gives you real-time data that reflects what your cardiovascular system is actually doing, not what an algorithm thinks it should be doing.
Rate of Perceived Exertion (RPE) is equally valuable and requires no equipment at all. On a scale from 1 to 10, where 1 is complete rest and 10 is absolute maximum effort, a genuinely effective cardio session should sit between 6 and 8 for most of its duration. If you’re comfortably chatting, scrolling your phone, and holding the handlebars, you’re probably at a 4 or 5, which isn’t harmful, but it’s not the workout the screen is suggesting you’re completing.
Some coaches advocate for tracking METs (Metabolic Equivalents of Task) rather than calorie totals, as this standardised measure of exercise intensity is less dependent on individual machine calibration. Most modern ellipticals do display MET values somewhere in their data screens, though users rarely seek them out. A MET value above 6 during a session indicates moderate-to-vigorous activity, regardless of what the calorie counter reads.
Getting more from the machine you’ve been underusing
The elliptical, used well, is a genuinely effective low-impact cardio tool, particularly for people with knee or hip concerns who can’t comfortably run. The joint-sparing quality of the movement is real, and the option to vary resistance and incline means you can create meaningful progressive overload without the impact stress of a treadmill.
The practical fix is straightforward. Drop the handles for at least half of your session, focus on driving through your heels rather than your toes (this recruits the posterior chain more effectively), and use resistance increases rather than speed to build intensity. If you need accountability, wear a heart rate monitor and aim to keep your rate within a target zone for your age, the NHS provides general physical activity guidelines that include heart rate context for cardiovascular exercise.
One detail that surprises most people: standing more upright on the elliptical, without the forward lean that hand-gripping often encourages, increases core muscle activation by a measurable amount, according to biomechanics research on elliptical posture. Your abdominals and spinal stabilisers work continuously to keep you balanced on the pedals, but only if you let them. The machine was designed to engage your whole body. The handles were included as a safety feature, not as a permanent crutch. There’s a meaningful difference between the two.
Always consult your GP before beginning a new exercise programme, particularly if you have existing health conditions or are returning to exercise after illness or injury.
