Flutter Kicks
Lie on your back and alternate small, quick leg kicks while keeping the lower back pressed to the floor.
Overview
Flutter Kicks is an intermediate core drill on Flexor. Lying on your back, you alternate small leg kicks while keeping the lower back pressed down.
What Flutter Kicks targets
The lower abdominals and deep core work to keep the lumbar spine stable while the legs scissor.
Why add Flutter Kicks to your routine
Builds lower abdominal endurance through sustained leg motion.
- Trains the core to resist lumbar extension during movement.
- Fits into short core finishers or warm-up activation blocks.
Who it's for
Anyone who can keep the lower back down during basic supine core work.
When to do it
Use at the end of core sessions or as a brief activation drill — about 45 seconds.
Flutter Kicks are a supine core drill where both heels lift slightly off the floor and alternate in a scissor motion. Brace the abdomen, press the low back down, and keep kicks small if the back starts to arch.
Setup cue
Lie on your back with legs long and hands under hips if needed. Brace your core and press the low back toward the floor.
Practice notes
In Flexor, Flutter Kicks is typically prescribed as about 45 sec per round, 1 rep, and 1 set. Adjust the dosage to what feels sustainable, breathe steadily, and ease off if anything feels sharp or unsafe.
Guidance
How to perform, tips, mistakes, safety notes, and benefits for Flutter Kicks.
Follow these cues in order. Move with control and stay in a comfortable range.
- Lie on your back with legs long; place hands under the hips if needed for support.
- Brace your core and press the lower back firmly into the floor.
- Lift both heels a few inches, then alternate small up-and-down kicks.
- Keep the kicks controlled; bend the knees if your lower back lifts off the mat.
Cues that help the movement stay smoother and more controlled.
- Press the lower back into the floor before the legs start moving.
- Keep kicks small and quick rather than large and swinging.
- Breathe steadily — exhale as the legs alternate.
Patterns to watch for so the shape stays clearer.
- Letting the lower back arch off the floor as fatigue sets in.
- Making kicks too large and losing core tension.
- Holding the breath instead of maintaining a steady rhythm.
Keep things comfortable and stop if something feels wrong.
- Stop if you feel sharp pain, numbness, tingling, dizziness, or symptoms that radiate.
- Stay within a comfortable, controlled range; muscular effort or mild stretch tension should not become pain.
- Move smoothly without bouncing, jerking, or forcing the range.
Why people include this movement in their practice.
- Builds lower abdominal endurance through sustained leg motion.
- Trains the core to keep the lumbar spine stable during movement.
