After trying flutter kicks for a month, I would recommend the move to most people—here's why

Woman wears gym kit and lays on her back on the floor with both legs raised off the floor, legs are straight.

I have quite a strong set of core muscles thanks to regular Pilates and strength work. However, one exercise that I have always struggled with is flutter kicks.

It’s a more advanced move, requiring a significant amount of effort from your lower abdominal muscles.
