Flutter kicks are the seated ab exercise you need if you’d like to build stronger lower abs, hip flexors and quads simultaneously. I added them to my and my client’s exercise routine recently, reminding me why I love the core exercise.
This ab exercise isn’t complicated but can be cruel to your lower back if you don’t engage your core properly or adopt “proper form.” With that in mind, I spend a lot of time ensuring my clients exercise safely, so I’ve included how to do flutter kicks properly below, common mistakes to watch out for, plus reasons why they're an epic bodyweight exercise to try.
