Exercise guide

Lean Back Heel Tap

  • Beginner
  • Compound
  • Rep-based
  • Core

The Lean Back Heel Tap is a beginner-friendly core exercise that builds stability in the rectus abdominis and obliques while strengthening the hip flexors and quads. By maintaining a static lean, you create constant tension in the midsection while the alternating leg movement challenges rotational stability.

Setup

  1. Sit on the floor with your knees bent and feet flat, hip-width apart.
  2. Lean your torso back to approximately a 45-degree angle until you feel your core engage.
  3. Keep your spine neutral and chest lifted, placing your hands lightly on the floor behind you for support.

How to do it

  1. Exhale and extend one leg forward, tapping your heel lightly on the floor while keeping the other foot planted.
  2. Inhale as you pull the leg back to the starting position using your lower abs and hip flexors.
  3. Alternate sides for each repetition, maintaining a steady, controlled tempo.
  4. Ensure your torso remains perfectly still and your chest stays open as the legs move.

Form checklist

  • Avoid rounding your shoulders or slouching your lower back.
  • Keep your core braced as if someone is about to poke your stomach.
  • Ensure the movement comes from the hip, not just the knee.
  • Keep your neck neutral by looking slightly upward and forward.

Pro tips

  • To maximize oblique engagement, focus on resisting the urge for your torso to twist toward the moving leg.
  • Squeeze your quadriceps at the point of the heel tap to increase lower body tension and stability.

Make it harder

  • Lift your hands off the floor and hold them straight out in front of you or behind your head to remove support.
  • Hover both feet off the floor in a V-sit position and perform the taps without letting the resting foot touch the ground.
