Estimate calories and kilojoules burned doing sit-to-stand exercise (also called chair rises or chair stands) — repeatedly standing up from a seated position and sitting back down, with or without using your hands for assistance. This calculator uses two pace-based MET tiers from the Conditioning Exercise section of the 2024 Adult Compendium of Physical Activities: a moderate pace of 6-12 repetitions per minute and a fast pace of 18-24 repetitions per minute. Sit-to-stand is a cornerstone movement in physiotherapy, falls-prevention programs for older adults, and cardiac and pulmonary rehabilitation, and it also works well as a simple, equipment-free lower-body exercise for anyone. Sessions tend to be short — a few minutes of repeated reps rather than a long workout — so this calculator defaults to a 10-minute duration.
Sit-to-stand calorie burn is estimated with calories = MET × body weight (kg) × duration (hours), using two pace-based MET values from the Conditioning Exercise section of the 2024 Adult Compendium of Physical Activities: moderate pace, 6-12 reps per minute (MET 2.8) and fast pace, 18-24 reps per minute (MET 4.0). An 80 kg person doing a 15-minute session burns around 56 kcal (about 234 kJ) at moderate pace, or around 80 kcal (about 335 kJ) at fast pace. Neither MET value used on this page is flagged by the Compendium as an estimated figure — both are literature-supported.

The calculation uses a MET (Metabolic Equivalent of Task) value for your rep pace, your body weight, and how long you trained. This calculator uses two MET tiers taken directly from the Conditioning Exercise section of the 2024 Adult Compendium of Physical Activities — moderate pace, 6-12 reps per minute (code 02340, MET 2.8) and fast pace, 18-24 reps per minute (code 02344, MET 4.0). Neither of these two codes is flagged as an estimated figure in the Compendium — both are literature-supported entries. Because sit-to-stand 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.
| Pace | MET | Calories (80 kg, 15 min) | Kilojoules |
|---|---|---|---|
| Moderate pace (6-12 reps/min) | 2.8 | 56 kcal | 234 kJ |
| Fast pace (18-24 reps/min) | 4.0 | 80 kcal | 335 kJ |
Sit-to-stand exercise is exactly what it sounds like: starting seated in a chair, standing all the way up, then lowering back down under control and repeating. It can be done using only your legs and core, or with a light push from your hands on the chair arms or your thighs if you need the extra assistance to get started — either way, it trains one of the most fundamental movement patterns the human body performs, something most people repeat dozens of times a day without thinking about it, from getting off the couch to standing up from the toilet or a car seat. That everyday relevance is exactly why it's used so heavily in clinical settings rather than being treated as just another gym exercise.
In physiotherapy, sit-to-stand is one of the most common functional-strength exercises prescribed, because it directly trains the quadriceps, glutes and hip muscles in the pattern they're actually used in daily life, rather than in an isolated machine-based movement. In falls-prevention programs for older adults, it's a staple: the ability to rise from a chair unaided and with good control is closely linked to lower-limb strength and balance, both of which are strong predictors of fall risk. Clinicians and exercise physiologists also use a 30-second or 1-minute sit-to-stand test as a simple, standardised way to track a patient's functional lower-body strength over time, which is part of why the movement is so well studied and so consistently prescribed. In cardiac and pulmonary rehabilitation, sit-to-stand shows up again for a different reason: it's a low-impact way to raise heart rate and build exercise tolerance in a controlled, seated-start position, without the joint loading of higher-impact cardio, which suits patients who are rebuilding fitness gradually after a cardiac event, surgery, or a period of illness. Outside of any clinical program, it also works well simply as an accessible, equipment-free lower-body exercise for people of any age and fitness level — you don't need a gym, a chair is enough.
The two tiers on this calculator both describe the same underlying movement — the sit-to-stand rep — at two different repetition speeds. Moderate pace, 6-12 reps per minute, is a controlled, unhurried rhythm: enough time to stand up and sit back down with good form, which is the pace most commonly used in physiotherapy sessions, falls-prevention classes, and cardiac or pulmonary rehab programs, where control and correct technique matter more than speed. Fast pace, 18-24 reps per minute, is a noticeably brisker rhythm that raises the cardiovascular and muscular demand considerably — this pace is used more in general conditioning contexts, once someone has built a comfortable base of strength and control at the slower pace, and it's a genuinely more demanding effort even though the movement itself hasn't changed. Neither pace is inherently "correct" — the right one depends on your goals, your current strength and balance, and, in a clinical context, the guidance of your treating health professional.
The table below holds the pace constant at moderate (MET 2.8) for a 15-minute session, so you can see how much body weight alone changes the total.
| Body Weight | MET | Calories (15 min) | Kilojoules |
|---|---|---|---|
| 55 kg | 2.8 | 39 kcal | 161 kJ |
| 65 kg | 2.8 | 46 kcal | 190 kJ |
| 75 kg | 2.8 | 53 kcal | 220 kJ |
| 85 kg | 2.8 | 59 kcal | 249 kJ |
| 95 kg | 2.8 | 67 kcal | 278 kJ |
Sit-to-stand sessions are usually short bursts of repeated reps rather than long workouts, so the durations below are deliberately brief. Here body weight is fixed at 80 kg while session length and pace both change, so you can compare how a longer set and a faster pace each add to the total.
| Session Length | Moderate Pace (MET 2.8) | Fast Pace (MET 4.0) |
|---|---|---|
| 5 minutes | 19 kcal / 78 kJ | 27 kcal / 112 kJ |
| 10 minutes | 37 kcal / 156 kJ | 53 kcal / 223 kJ |
| 15 minutes | 56 kcal / 234 kJ | 80 kcal / 335 kJ |
| 20 minutes | 75 kcal / 312 kJ | 107 kcal / 446 kJ |
Australian nutrition panels list energy in kilojoules, not calories, so it's worth converting your sit-to-stand total into the same unit your food packaging uses. Multiply your calorie figure by 4.184 to get kilojoules. An 80 kg person doing a 15-minute session at fast pace burns about 80 kcal, which is roughly 335 kJ — a modest but genuine number worth keeping in perspective, since a few minutes of chair rises isn't intended to replace a longer cardio session, but rather to add functional lower-body strength work that's easy to fit into a day.
How many calories does sit-to-stand exercise burn?
It depends on your pace and session length. Using this calculator's two tiers for an 80 kg person over a 15-minute session: moderate pace, 6-12 reps per minute (MET 2.8) burns about 56 kcal (234 kJ), and fast pace, 18-24 reps per minute (MET 4.0) burns about 80 kcal (335 kJ). Lighter or heavier bodies, 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 calories burned doing sit-to-stand exercise calculated?
The calculator multiplies a MET (Metabolic Equivalent of Task) value for your rep pace by your body weight in kilograms and your session duration in hours: calories = MET × body weight (kg) × duration (hours). Because sit-to-stand sessions are usually measured in minutes rather than hours, the calculator takes your minutes input and divides by 60 before running the formula. The two MET values used — 2.8 for moderate pace, 6-12 reps per minute (code 02340), and 4.0 for fast pace, 18-24 reps per minute (code 02344) — 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 sit-to-stand exercise, and why?
A genuinely wide range of people. It's a cornerstone exercise in physiotherapy, falls-prevention & cardiac and pulmonary rehab programs, because it directly trains functional lower-body strength in the exact movement pattern used dozens of times a day — standing up from a chair, a couch, or a car seat. Clinicians also use short sit-to-stand tests as a simple way to track a patient's functional strength over time. Outside clinical settings, it's also used more broadly as an accessible, equipment-free lower-body conditioning exercise for people of any age who want a simple way to build leg and hip strength at home.
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 moderate pace (MET 2.8) for a 15-minute session, a 95 kg person burns roughly 67 kcal compared with about 39 kcal for a 55 kg person completing the identical session at the identical pace.
What are the limitations of this estimate?
This calculator gives a general estimate based on published MET values for two rep-pace tiers, not a measurement of your individual energy expenditure. It doesn't account for chair height, whether you use your hands for assistance, how deep or controlled each rep is, your muscle mass, or your individual fitness level, all of which can meaningfully change how demanding a session actually feels and how much energy it truly costs. Treat the result as a reasonable planning figure rather than a clinical measurement, particularly if you're using sit-to-stand as part of a rehabilitation or falls-prevention program with specific goals set by a health professional.
Is sit-to-stand exercise safe for older adults or people recovering from surgery or injury?
For most people, sit-to-stand is considered a low-risk, low-impact exercise, which is exactly why it's used so widely in falls-prevention and rehab programs. That said, people with balance issues, recent surgery (particularly hip, knee or spinal surgery), joint conditions such as arthritis, or any condition affecting strength or stability should follow the specific guidance of their physiotherapist or doctor before starting a sit-to-stand program, including advice on chair height, hand assistance, and safe progression. It's a widely recommended exercise, but "widely recommended" isn't the same as "right for everyone without individual guidance."
How many reps count as one minute at each pace?
The Compendium defines moderate pace as 6-12 sit-to-stand repetitions per minute — roughly one rep every 5 to 10 seconds, unhurried and controlled — and fast pace as 18-24 repetitions per minute, closer to one rep every 2.5 to 3.5 seconds, a noticeably brisker rhythm. Most physiotherapy, falls-prevention and rehab programs start at or below the moderate pace to prioritise control and correct technique, with faster paces generally introduced later as strength, balance and confidence improve.
