Calories Burned Water Aerobics: Chart by Weight and Calculator
Last updated
This page estimates the calories you burn doing water aerobics. The table uses metabolic equivalents from the Adult Compendium of Physical Activities to give you a baseline for different body weights.
Keep in mind that these numbers are only estimates for a typical adult. Your real calorie burn varies based on your fitness level, technique, body composition, and how hard you actually work. Fitness trackers also just estimate your output.

| Time | 120 lb 54 kg |
150 lb 68 kg |
180 lb 82 kg |
210 lb 95 kg |
240 lb 109 kg |

| 60 min | 314 | 393 | 472 | 550 | 629 |
Calculate your own estimate
The formula. kcal = MET × 3.5 × body weight in kg ÷ 200 × minutes.
Worked example. Water aerobics, water calisthenics, general: 5.5 × 3.5 × 68.0 kg (150 lb) ÷ 200 × 30 min = about 196 kcal.
Which row is you?
The table breaks down water aerobics into three categories based on your effort and routine type. Choose the resistance exercises row if you use water weights or bands at a steady, moderate pace. Select the general water calisthenics row for a standard class with continuous movement. Pick the high intensity row if you are doing vigorous cardiovascular intervals that leave you breathing heavily. To find your estimate, match your workout style to the description, then look under the column that is closest to your current body weight.
What changes the real number
- Water depth and temperature, which change how your body regulates heat and moves against resistance.
- The amount of drag created by your swimsuit or any aquatic equipment you use.
- Your familiarity with the movements, since beginners often use more energy to stay balanced.
- The actual duration of your active movement compared to resting between class instructions.
Practical tips
- Keep your feet firmly planted on the pool floor to maximize resistance and avoid floating through the movements.
- Submerge your arms and shoulders to ensure you are pushing against the water rather than just moving through the air.
- Log only the minutes you spend actively moving, subtracting any time spent listening to the instructor or resting at the wall.
About these numbers. MET values describe the average energy cost of an activity for adults; your own burn can be noticeably higher or lower. The values include resting energy use, so the extra calories from exercise are a little lower than the total shown. A separate Older Adult Compendium exists for people aged 60 and over.
Compare with similar activities
When to stop and see a doctor
- Sudden dizziness or lightheadedness when transitioning between standing and moving.
- Sharp pain in your joints or back that worsens as you push against the water.
- Chest pressure or severe shortness of breath that feels disproportionate to your effort level.
