Exercise guide

V-Up Down With Stability Ball

  • Intermediate
  • Compound
  • Rep-based
  • Waist

This compound core exercise targets the entire abdominal wall and hip flexors by using a stability ball to increase resistance and coordination. The transfer of the ball between hands and feet creates a high level of tension throughout the rectus abdominis and obliques.

Equipment

  • Stability ball

Setup

  1. Lie flat on your back with your legs fully extended and arms reaching overhead.
  2. Hold the stability ball firmly between your hands.
  3. Engage your core by pressing your lower back into the floor to eliminate any arching.

How to do it

  1. Simultaneously lift your torso and legs to form a 'V' shape, exhaling as you bring the ball toward your shins.
  2. Transfer the ball from your hands to your ankles, squeezing it firmly between your lower legs.
  3. Inhale as you lower your arms and legs back toward the floor in a controlled 2-3 second tempo.
  4. Stop just before your heels and hands touch the ground, then repeat the movement to transfer the ball back to your hands.

Form checklist

  • Keep your lower back in contact with the floor as long as possible during the descent.
  • Maintain straight arms and legs throughout the entire range of motion.
  • Avoid using momentum; move with control rather than swinging your limbs.
  • Keep your neck neutral by looking toward the ball as you rise.

Pro tips

  • Squeeze the stability ball with your inner thighs or ankles to increase lower abdominal and adductor activation.
  • Focus on 'peeling' your spine off the mat one vertebra at a time to maximize the contraction of the rectus abdominis.

Make it harder

  • Add a three-second isometric hold at the top of the 'V' when the ball is being transferred.
  • Slow down the lowering phase to a 5-second count to maximize time under tension.
