Estimate calories and kilojoules burned on an arm ergometer (a hand-crank machine, often called a "hand bike"), based on your body weight, effort level, and session length. This calculator uses three wattage-based MET tiers from the Conditioning Exercise section of the 2024 Adult Compendium of Physical Activities: light effort at 15 watts, moderate effort at 25-30 watts, and higher effort at 45 watts. Arm ergometers are a genuine cardio and rehabilitation tool, not a niche gym curiosity — they're used every day by wheelchair users, people recovering from lower-limb injury or surgery, cardiac rehab patients, and athletes training upper-body conditioning specifically.
Arm ergometer (hand bike) calorie burn is estimated with calories = MET × body weight (kg) × duration (hours), using three wattage-based MET values from the Conditioning Exercise section of the 2024 Adult Compendium of Physical Activities: light effort at 15 watts (MET 2.0), moderate effort at 25-30 watts (MET 2.8), and higher effort at 45 watts (MET 3.5). A 75 kg person over a 30-minute session burns around 75 kcal (about 314 kJ) at light effort, around 105 kcal (about 439 kJ) at moderate effort, and around 131 kcal (about 549 kJ) at higher effort. All three MET values are literature-supported entries in the Compendium, not flagged as estimated figures.
| Effort Level | MET | Calories | Kilojoules |

The calculation uses a MET (Metabolic Equivalent of Task) value for your chosen effort level, your body weight, and how long you cranked. This calculator uses three MET tiers taken directly from the Conditioning Exercise section of the 2024 Adult Compendium of Physical Activities — light effort at 15 watts (code 02116, MET 2.0), moderate effort at 25-30 watts (code 02117, MET 2.8), and higher effort at 45 watts (code 02118, MET 3.5). None of these three codes are flagged as estimated in the Compendium — all three are literature-supported entries. Because arm ergometer sessions are usually measured in minutes rather than hours, the calculator takes your minutes input and converts it to hours (hours = minutes ÷ 60) before applying the formula.
| Effort Level | MET | Calories (75 kg, 30 min) | Kilojoules |
|---|---|---|---|
| Light effort (15W) | 2.0 | 75 kcal | 314 kJ |
| Moderate effort (25-30W) | 2.8 | 105 kcal | 439 kJ |
| Higher effort (45W) | 3.5 | 131 kcal | 549 kJ |
An arm ergometer — often called a hand-crank machine or hand bike — works like a stationary bike that you turn with your hands and arms instead of your legs. You sit, or use your own wheelchair, in front of the machine and crank a set of pedals mounted around chest or shoulder height, working against an adjustable resistance measured in watts. You'll find them in gyms, but far more commonly in hospitals, physiotherapy clinics and cardiac rehabilitation units, because they solve a specific problem: how do you give someone genuine cardiovascular exercise when their legs aren't available for training?
For many wheelchair users, that's not a hypothetical question, it's daily reality. Most cardio equipment in a standard gym — treadmills, stationary bikes, ellipticals — is built around leg movement and simply isn't usable. An arm ergometer removes that barrier, offering a way to raise heart rate, build endurance and get a structured cardio session using the arms and shoulders alone. The same logic applies to people recovering from a lower-limb injury or surgery: an ACL reconstruction, a hip or knee replacement, a lower-leg fracture, or an amputation can all rule out leg-based training for weeks or months at a time. Cardiovascular fitness declines fairly quickly once training stops altogether, so an arm ergometer lets someone keep that fitness ticking over while the legs heal, rather than starting from scratch once they're cleared to walk or run again.
Arm ergometers are also a mainstay of cardiac rehabilitation programs in Australian hospitals and clinics, where patients recovering from a heart attack, bypass surgery or another cardiac event build exercise tolerance gradually and under supervision. The controlled, seated, low-impact nature of hand-cranking makes it a practical way to monitor heart rate and effort closely in the early stages of recovery. Beyond rehab settings, athletes use arm ergometers too: wheelchair sport athletes such as wheelchair racers and wheelchair basketball players, for whom upper-body output is the primary engine, along with rowers, swimmers and other athletes layering in dedicated upper-body conditioning work. For a leg-based point of comparison, our Calories Burned Cycling Calculator uses the same MET-based formula applied to whole-body cycling — putting the two side by side is a useful way to see just how much more total muscle mass, and therefore energy, gets engaged once the legs are doing the work alongside the arms.
If you've used a calorie calculator for cycling, running or another leg-based activity before, the MET values on this page — 2.0 to 3.5 — will look low by comparison. That's expected, and it isn't a sign that arm ergometer training doesn't count as real exercise. MET values reflect energy cost relative to how much muscle tissue is doing the work, and the legs simply contain a much larger share of the body's total muscle mass than the arms and shoulders. Because an arm ergometer only engages the upper body, it takes noticeably more perceived effort — a faster heart rate, heavier breathing — to reach the same MET value that leg-based cardio hits at a comparatively easier pace. In other words, cranking hard on an arm ergometer can feel just as demanding as a solid bike ride, even though the calorie total works out lower, simply because fewer muscles are sharing the load. For people who can't train their legs, that lower number doesn't make the workout less worthwhile — it's still genuine cardiovascular training, just measured against a smaller pool of working muscle.
Arm ergometer resistance is set in watts, a direct measure of the mechanical power you're producing by turning the crank, and this calculator uses three tiers spanning the range most machines and rehab protocols use. Light effort at 15 watts is a gentle, steady turning pace — the kind of resistance typically used for a warm-up, an early-stage rehab session, or a low-intensity active-recovery day, comfortable enough to sustain a conversation throughout. Moderate effort at 25-30 watts is a solid working pace that noticeably raises heart rate and breathing rate, the level most general conditioning and mid-stage rehab sessions are built around. Higher effort at 45 watts requires meaningfully more force and sustained effort per crank, generally used once someone has built up tolerance at the lower tiers, and sits closer to a genuinely vigorous upper-body effort.
The table below holds effort constant at the moderate effort tier (MET 2.8) for a 30-minute session, so you can see how much body weight alone changes the total.
| Body Weight | MET | Calories (30 min) | Kilojoules |
|---|---|---|---|
| 55 kg | 2.8 | 77 kcal | 322 kJ |
| 65 kg | 2.8 | 91 kcal | 381 kJ |
| 75 kg | 2.8 | 105 kcal | 439 kJ |
| 85 kg | 2.8 | 119 kcal | 498 kJ |
| 95 kg | 2.8 | 133 kcal | 556 kJ |
Session lengths vary a lot depending on whether you're doing a quick rehab set or a full conditioning session. Here body weight is fixed at 75 kg while duration and effort level both change, so you can compare how much a longer session and a harder effort each add to the total.
| Session Length | Light Effort (MET 2.0) | Moderate Effort (MET 2.8) | Higher Effort (MET 3.5) |
|---|---|---|---|
| 15 minutes | 38 kcal / 157 kJ | 53 kcal / 220 kJ | 66 kcal / 275 kJ |
| 30 minutes | 75 kcal / 314 kJ | 105 kcal / 439 kJ | 131 kcal / 549 kJ |
| 45 minutes | 113 kcal / 471 kJ | 158 kcal / 659 kJ | 197 kcal / 824 kJ |
| 60 minutes | 150 kcal / 628 kJ | 210 kcal / 879 kJ | 263 kcal / 1,098 kJ |
Australian nutrition panels list energy in kilojoules, not calories, so it's worth converting your session total into the same unit your food packaging uses. Multiply your calorie figure by 4.184 to get kilojoules. A 75 kg person doing a 30-minute session at higher effort (45 watts) burns about 131 kcal, which is roughly 549 kJ — a useful figure to weigh up against the energy value of a snack or recovery meal.
How many calories does an arm ergometer burn?
It depends on effort level and session length. Using this calculator's three tiers for a 75 kg person over a 30-minute session: light effort at 15 watts (MET 2.0) burns about 75 kcal (314 kJ), moderate effort at 25-30 watts (MET 2.8) burns about 105 kcal (439 kJ), and higher effort at 45 watts (MET 3.5) burns about 131 kcal (549 kJ). Lighter or heavier users, and shorter or longer sessions, will see proportionally lower or higher totals, so enter your own weight and session length above for a personalised estimate.
How is arm ergometer calorie burn calculated?
The calculator multiplies a MET (Metabolic Equivalent of Task) value for your chosen effort level by your body weight in kilograms and your session duration in hours: calories = MET × body weight (kg) × duration (hours). Because most sessions are measured in minutes rather than hours, the calculator takes your minutes input and divides by 60 before running the formula. The three MET values used — 2.0 for light effort at 15 watts (code 02116), 2.8 for moderate effort at 25-30 watts (code 02117), and 3.5 for higher effort at 45 watts (code 02118) — come directly from the Conditioning Exercise section of the 2024 Adult Compendium of Physical Activities. The kilocalorie result is then multiplied by 4.184 to give the equivalent figure in kilojoules, the unit used on Australian food labels.
Who typically uses an arm ergometer, and why?
Arm ergometers, also called hand-crank machines or hand bikes, are used by a genuinely wide range of people. For many wheelchair users, an arm ergometer is one of the few accessible ways to get structured cardiovascular exercise, since leg-based machines aren't usable. People recovering from lower-limb injuries, amputations or surgery use them to maintain cardio fitness while their legs heal, and they're a standard piece of equipment in cardiac rehab & physiotherapy clinics because they let patients build exercise tolerance under supervision without loading the lower body. Athletes — including wheelchair sport athletes, rowers and swimmers — also use them for dedicated upper-body conditioning work.
Why do upper-body-only workouts burn fewer calories than leg-based cardio at a similar effort?
MET values reflect how much energy an activity uses relative to resting metabolism, and that energy cost is driven largely by how much muscle mass is engaged. The arms and shoulders make up a much smaller share of total muscle mass than the legs, so even hard, sustained cranking on an arm ergometer recruits less tissue than pedalling a bike with the legs — which means it burns less energy per hour at a comparable perceived effort. This isn't a flaw in the numbers, and it doesn't mean arm ergometer training is less valuable; it's a genuine physiological difference between upper-body-only and whole-body exercise, and it matters most for people who don't have the option of leg-based training in the first place.
Does body weight affect the result?
Yes. Because calories equal MET multiplied by body weight in kilograms multiplied by duration in hours, body weight is a direct multiplier in the formula. At the moderate effort tier (MET 2.8) for a 30-minute session, a 95 kg person burns roughly 133 kcal compared with about 77 kcal for a 55 kg person completing the identical session at the identical effort level.
What are the limitations of this estimate?
This calculator gives a general estimate based on published MET values for three effort tiers, not a measurement of your individual energy expenditure. Actual calorie burn varies with cranking technique, cadence, fitness level, muscle mass, whether resistance is set precisely to 15, 25-30 or 45 watts, and individual metabolic differences. It also doesn't account for a specific health condition, medication, or rehabilitation stage, all of which can affect how your body responds to exercise. Treat the result as a reasonable planning figure rather than a clinical measurement, and follow any specific guidance from your treating health professional if you're using an arm ergometer as part of a rehabilitation program.
Is an arm ergometer a good cardio workout?
Yes, particularly for people who can't do leg-based cardio or want to add upper-body-specific conditioning. All three effort tiers used on this page represent genuine, measurable energy expenditure, and consistent arm ergometer sessions can improve cardiovascular fitness, arm and shoulder endurance, and exercise tolerance over time. It won't burn calories as quickly per hour as whole-body leg-based cardio such as cycling — see our Calories Burned Cycling Calculator for a direct comparison — but for wheelchair users, people in lower-limb rehab, or anyone training the upper body specifically, it's a legitimate and often essential form of cardio exercise rather than a lesser substitute.
How do I progress between wattage levels safely?
Most people start at the light effort tier (15 watts) to build tolerance, cranking technique and shoulder conditioning before increasing resistance. Moving up to moderate effort (25-30 watts) and eventually higher effort (45 watts) is generally done gradually, over multiple sessions or weeks rather than in a single workout, to reduce the risk of shoulder or wrist overuse strain. If you're using an arm ergometer as part of a cardiac rehab or post-surgical recovery program, follow the specific progression schedule set by your treating physiotherapist, exercise physiologist or cardiologist rather than increasing wattage on your own timeline.
