Sitting Flutter Kick On A Padded Stool

  • Beginner

This exercise targets the lower abdominals and hip flexors while improving core stability and endurance. Sitting on a stool increases the challenge to your balance and allows for a greater range of motion compared to performing the movement on the floor.

Equipment

Setup

  1. Sit on the edge of a padded stool or bench with your feet flat on the floor.
  2. Lean your torso back at a 45-degree angle while maintaining a neutral spine and proud chest.
  3. Grip the edges of the stool behind your hips for stability and lift both legs off the floor, extending them straight out.
  4. Engage your core by pulling your belly button toward your spine.

How to do it

  1. Exhale as you begin small, alternating up-and-down 'fluttering' kicks with your legs.
  2. Keep your legs straight and toes pointed, ensuring the movement originates from the hips rather than the knees.
  3. Inhale and exhale rhythmically, maintaining a steady tempo for the duration of the set.
  4. Keep your legs elevated throughout the movement, never letting your heels touch the floor.

Form checklist

  • Keep your chest lifted and avoid rounding your shoulders or lower back.
  • Ensure your knees remain locked or only slightly bent to keep tension on the abs.
  • Maintain a consistent lean-back angle to keep the core under constant tension.
  • Avoid using momentum; keep the kicks small, fast, and controlled.

Pro tips

  • Squeeze your quadriceps throughout the movement to help keep your legs straight and further engage the hip flexors.
  • Focus on pressing your lower back slightly forward to prevent arching, which protects the lumbar spine and maximizes abdominal recruitment.

Make it harder

  • Remove your hands from the stool and hold them out to your sides or across your chest to significantly increase the balance requirement.
  • Slow down the tempo of the kicks or increase the vertical range of the 'flutter' to increase time under tension.
