Flutter kicks exercise is also very effective in reducing belly fat. Even though seeing others doing this exercise seems very easy, but while doing it, there is a strain on the entire stomach, which causes fat burning. In this, you have to lift your legs upwards and move them as if you are kicking. Apart from this, raise both your legs and slowly bring them down while counting from 1 to 10. Hold the legs for 3 to 4 seconds on each count and then lower them.
