Exercise guide

V Sit Toe Tap

  • Intermediate
  • Compound
  • Rep-based
  • Lower legs
  • Upper legs
  • Waist

This dynamic core exercise challenges stability and balance while targeting the rectus abdominis and obliques through a controlled alternating movement. It effectively strengthens the hip flexors and deep core stabilizers by maintaining a constant isometric hold in the torso.

Setup

  1. Sit on the floor with your knees bent and feet flat, then lean your torso back to a 45-degree angle while keeping your spine neutral.
  2. Lift your feet off the floor with shins parallel to the ground, balancing on your sit bones in a 'V' shape.
  3. Extend your arms forward at shoulder height or place your hands lightly on the floor behind you for extra support.

How to do it

  1. Inhale and slowly lower one foot toward the floor, tapping your toes lightly while keeping the other leg and torso perfectly still.
  2. Exhale as you use your lower abdominals to lift the leg back to the starting 'V' position.
  3. Repeat the movement with the opposite leg, alternating sides in a slow, controlled tempo.

Form checklist

  • Maintain a proud chest and neutral spine; do not allow your lower back to round.
  • Keep the angle of your torso constant throughout the entire set.
  • Ensure the movement occurs at the hip joint rather than just bending the knee.
  • Keep your neck relaxed and gaze forward to avoid cervical strain.

Pro tips

  • Focus on the 'hollow body' sensation by pulling your navel toward your spine to maximize deep abdominal engagement.
  • Minimize any rocking or swaying of the upper body to force the core to work harder as a stabilizer.

Make it harder

  • Perform the toe taps with straight legs to increase the lever length and resistance.
  • Hold a light medicine ball or dumbbell at chest level to add resistance and further challenge your balance.
