Flutter kicks (hands under - hips head up) are a body-weight core exercise where you lie on your back with your hands tucked under your hips and your head lifted, then alternate small, rapid up-and-down kicks with straight legs. The constant leg motion challenges the lower abdominals and hip flexors while teaching you to keep your trunk braced under tension.

How to do the Flutter Kicks (hands under - hips head up)

  1. 1Lie flat on your back and slide your hands palms-down underneath your hips to support your lower back.
  2. 2Lift your head and shoulders slightly off the floor and raise both legs a few inches off the ground with your knees straight.
  3. 3Brace your core and press your lower back gently into your hands so it stays in contact throughout.
  4. 4Kick one leg up while the other lowers toward the floor, keeping both legs straight and feet pointed.
  5. 5Reverse the motion, alternating legs in a controlled, fluttering rhythm.
  6. 6Keep the kicks small and steady, never letting your feet touch the floor.
  7. 7Continue for your target time or rep count, then lower both legs to the floor to finish.

Form tips

  • Keep your lower back pressed into your hands the whole set to protect your spine and keep tension on the abs.
  • Hold your legs low rather than high — the closer your feet are to the floor, the harder your core has to work.
  • Breathe steadily through the kicks instead of holding your breath, so you can maintain the rhythm.
  • Keep the movement small and controlled; speed comes from rhythm, not from swinging your legs.

Common mistakes

  • Letting your lower back arch up off your hands, which shifts the load onto your spine and risks strain.
  • Kicking the legs too high, which reduces tension on the abdominals and turns the move into a leg raise.
  • Bending the knees instead of keeping the legs straight, which cheats the range and lessens the challenge.
  • Tensing the neck by yanking the head up — keep the lift small and let your core, not your neck, do the work.

Frequently asked questions

What muscles do flutter kicks work?

Flutter kicks are a body-weight core movement that mainly challenges the lower abdominals and hip flexors, with the rest of the trunk working to keep you braced and stable throughout the kicks.

Why do I put my hands under my hips?

Tucking your hands under your hips supports your lower back and helps keep your spine from arching off the floor, so you can keep tension on your abs and kick safely.

Are flutter kicks good for beginners?

Yes. They need no equipment and the difficulty is easy to scale — kick higher and slower, or for a shorter time, when starting out, then lower your legs and extend the set as you get stronger.

How long should I do flutter kicks for?

A common approach is 3 to 4 sets of 20 to 40 seconds, or 15 to 25 reps per leg. Stop the set once your lower back starts to lift off your hands.
