How many calories do flutter kicks burn?

Standard flutter kicks burn approximately 3.5 MET, or about 4–6 calories per minute for a 70 kg person. A 10-minute session burns roughly 40–60 calories depending on body weight and intensity.

Are flutter kicks a good ab exercise?

Flutter kicks effectively target the lower abdominals and hip flexors. They also engage the quadriceps as secondary movers. They are commonly used in core training circuits and military-style fitness programs.

How do I convert reps to time?

Use the reps-to-time converter in this calculator. At moderate tempo, 100 flutter kicks take approximately 3.3 minutes. Slow tempo adds about 25% more time, while fast tempo reduces it by about 25%.

Do weighted flutter kicks burn more calories?

Yes. Adding ankle weights increases the MET value from 3.5 to approximately 4.5, which is about a 30% increase in calorie burn for the same duration.

Key Takeaways

Flutter kicks primarily target the lower abdominals and hip flexors while engaging the quadriceps and glutes as stabilizers.^[1]
Standard flutter kicks burn approximately 3.5 MET, which translates to roughly 4–6 calories per minute for most adults.^[2]
Adding ankle weights or performing flutter kicks in water can increase energy expenditure by 30–40% compared to the bodyweight version.^[3]

How the Calculator Works

Calories = MET × Body Weight (kg) × Duration (hours)

Each flutter kick variation has a specific MET (Metabolic Equivalent of Task) value derived from the Compendium of Physical Activities and exercise physiology research.^[2]

The optional reps-to-time converter estimates how long a given rep count takes based on your selected tempo: slow (2.5 sec/rep), moderate (2.0 sec/rep), or fast (1.5 sec/rep).

Limitations and Important Notes

MET-based estimates are population averages — individual calorie burn depends on fitness level, muscle mass, and movement efficiency.
Flutter kicks are typically performed in short sets (30–60 seconds), so total calorie burn per session tends to be modest.
