About Step Aerobics and Calorie Burn
Step aerobics involves performing choreographed movements stepping on and off an elevated platform (step bench) to music. The repeated stepping motion, combined with arm movements and directional changes, provides an excellent cardiovascular workout that targets the lower body. Step aerobics was one of the first group fitness formats and remains popular because it effectively burns calories while being lower impact than running. Adjusting the step height allows for easy intensity modification to suit any fitness level.
Understanding the MET Value
Aerobic step, 6-8 inch step has a MET (Metabolic Equivalent of Task) value of 7.3. This means aerobic step, 6-8 inch step burns 7.3 times more energy than sitting at rest. The formula used is: calories = MET x 3.5 x body weight in kg / 200 x minutes. For example, a 70 kg person doing aerobic step, 6-8 inch step for 1 hour would burn approximately 537 calories. MET values are sourced from the Compendium of Physical Activities and should be treated as useful estimates, not exact lab measurements.
Step Aerobics MET Values by Sub-Activity (Compendium of Physical Activities)
The 2024 Compendium of Physical Activities (Ainsworth et al., updated from 2011) breaks step aerobics into specific sub-activities, each with its own MET value reflecting the metabolic cost of that movement pattern. Use the table below to match your training to a closer estimate.
| Sub-activity | MET | Compendium Code | Calories / 30 min (160 lbs) | Notes |
|---|---|---|---|---|
| Aerobic step, 4-inch step | 5.5 | 02001 | 210 | Best for beginner classes, lower platform height, or lower-impact choreography. |
| Aerobic step, 6-8 inch step | 7.3 | 02002 | 278 | Good default for a typical moderate-to-vigorous step aerobics class. |
| Bench step class, general | 7.8 | 02004 | 297 | Use for general bench-step classes when step height and impact are mixed. |
| Aerobic step, 10-12 inch step | 9 | 02003 | 343 | Use only for high step height, faster choreography, and vigorous effort. |
Citation: 2024 Adult Compendium of Physical Activities, Conditioning Exercise category: codes 02001, 02002, 02003, and 02004 list step-aerobics and bench-step activities from 5.5 to 9.0 MET.
Tips to Maximize Your Step Aerobics Calorie Burn
- Start with a lower step height (4-6 inches) and increase as fitness improves
- Step fully onto the platform with your entire foot — never let your heel hang off
- Keep your core engaged and maintain upright posture throughout the workout
- Add arm movements to increase calorie burn and upper body engagement
- Focus on the basic steps first before attempting complex choreography patterns

How We Calculate Calories Burned During Step Aerobics
Our step aerobics calorie calculator uses the standard MET oxygen-cost equation, a common method used in exercise science and public-health research. For this calculation we use aerobic step, 6-8 inch step at MET 7.3. The formula is:
Calories = MET x 3.5 x Weight (kg) / 200 x Minutes
For aerobic step, 6-8 inch step with a MET value of 7.3, the calculation works as follows: If you weigh 160 lbs (72.6 kg) and do step aerobics for 30 minutes (0.5 hours), you would burn approximately 278 calories.
Keep in mind that actual calorie expenditure can vary by 15-20% based on factors like fitness level, exercise intensity, environmental conditions, and individual metabolic differences. The selected MET value of 7.3 for aerobic step, 6-8 inch step represents an average across typical conditions and effort levels. Your actual burn may be higher or lower depending on how vigorously you perform the activity.

View All ActivitiesMethodology & Calorie Burn Data Sources
How we calculate step aerobics calorie burn: The MET (Metabolic Equivalent of Task) value of 7.3 for step aerobics comes from the Compendium of Physical Activities (Ainsworth et al.), a standardized reference used in exercise and public-health research. Calorie expenditure follows the formula: kcal/min = (MET x 3.5 x weight in kg) / 200, then multiplied by duration.
- MET value for step aerobics: 7.3 (low MET = light, 3-6 = moderate, >6 = vigorous per ACSM classification).
- Body weight scaling: heavier individuals burn more calories per minute at the same activity. Our calculator adjusts based on your input weight.
- Duration scaling: linear with time at constant intensity. Real workouts may include warm-up, cool-down, and rest periods affecting average MET.
- Individual variation: actual burn varies ±10-20% based on fitness level, body composition, exercise efficiency, and metabolic rate.
- EPOC (afterburn effect): high-intensity activities may burn additional calories post-workout, but that extra burn varies widely and is not included in baseline figures.

Health Disclaimer: Calorie burn estimates are general guidance, not precise measurements. Wearable devices (Apple Watch, Fitbit, Garmin) using heart rate provide more personalized estimates. Always consult a physician before starting an exercise program, especially if you have heart conditions, diabetes, or are pregnant. Never use exercise to "earn" food in a way that disrupts a healthy relationship with eating.

Frequently Asked Questions
How many calories does step aerobics burn in 30 minutes?
A person weighing 160 lbs (73 kg) burns approximately 278 calories during 30 minutes of step aerobics. This is based on a MET value of 7.3 for aerobic step, 6-8 inch step. Heavier individuals burn more calories, and lighter individuals burn fewer.
What is the MET value of step aerobics?
The default MET (Metabolic Equivalent of Task) value for step aerobics is 7.3, while the selected training style uses MET 7.3. This means aerobic step, 6-8 inch step burns 7.3 times more energy than sitting at rest. MET values are established by the Compendium of Physical Activities and represent average energy expenditure for the activity.
Is step aerobics good for weight loss?
Yes, step aerobics can be effective for weight loss when performed intensely enough. With a selected MET value of 7.3, a 160-lb person burns about 556 calories per hour. Combined with a balanced diet, regular step aerobics can help create the calorie deficit needed for weight loss.
How does body weight affect calories burned during step aerobics?
Body weight significantly impacts calorie burn during step aerobics. At the selected MET value of 7.3, a 120-lb person burns about 209 calories in 30 minutes, while a 250-lb person burns approximately 435 calories in the same time. This is because moving a heavier body requires more energy, regardless of the activity being performed.
What muscles does step aerobics work?
Step Aerobics primarily works the Quadriceps, Glutes, Hamstrings, Calves, and Core. The high intensity of this exercise also provides significant cardiovascular conditioning.
How many calories does 30 minutes of step aerobics burn for a 185-lb person?
A 185-lb person burns about 294 calories in 30 minutes of low-impact step aerobics and about 420 calories in 30 minutes of high-impact step aerobics in the Harvard Health benchmark table. Using the 2024 Adult Compendium MET equation, the estimate ranges from about 242 calories at a 4-inch step (5.5 MET) to about 397 calories at a 10-12 inch step (9.0 MET).
What MET value should I use for step aerobics?
Use 5.5 MET for a 4-inch step, 7.3 MET for a 6-8 inch step, 7.8 MET for a general bench-step class, and 9.0 MET for a 10-12 inch step or vigorous class. Step height, choreography speed, arm movement, and rest breaks can change the correct estimate.
Why does Harvard Health show different step aerobics calories than a MET calculator?
Harvard Health publishes benchmark calories for 125-lb, 155-lb, and 185-lb people, while this calculator uses the MET formula with your exact body weight and selected step-aerobics intensity. The two methods should be treated as planning estimates, not lab measurements.
