Flutter Kicks

BWBodyweightStrength

No video available

Flutter kicks are a bodyweight exercise where you lie on your back with hands under your glutes, then rapidly alternate lifting each leg slightly off the ground in a fluttering motion while keeping your core braced and lower back pressed down. The primary purpose is to build endurance and strength in the lower abdominals through sustained isometric holds and dynamic movement. It mainly targets the abs, with secondary engagement of the hip flexors, making it ideal for beginners, athletes seeking core stability, or anyone improving endurance without equipment.

How to Perform Flutter Kicks

  1. 1Lie face up on a mat with your legs extended straight and together, arms resting by your sides with palms down.
  2. 2Engage your core by pressing your lower back into the floor.
  3. 3Lift your head, neck, and shoulders slightly off the ground, gazing toward your toes.
  4. 4Raise both legs about 6-12 inches off the ground, keeping them straight and toes pointed.
  5. 5Begin the movement: alternate kicking one leg up slightly while lowering the other, like swimming flutter kicks (inhale steadily through the nose).
  6. 6Continue alternating legs in a rapid, controlled scissor motion for desired reps or time (exhale steadily through the mouth).
  7. 7Lower your legs, head, and shoulders back to the starting position to rest.
  8. 8Key form tips: Keep your lower back pressed into the floor to avoid arching—place hands under your glutes if needed. Move legs from the hips, not knees, for better ab engagement. Avoid swinging or using momentum; common mistake is lifting head too high, straining the neck.
