Muscles worked

  • Hip flexors

Equipment

  • Body weight

Setup

  1. Lie flat on your back with your legs fully extended and arms reaching overhead.
  2. Press your lower back into the floor to engage your core and eliminate any arch.
  3. Hover your heels and hands 2-3 inches off the ground to create constant tension.

How to do it

  1. Simultaneously lift your torso and one leg while rotating your upper body to bring the opposite elbow toward the rising knee.
  2. Exhale forcefully at the top of the movement, aiming for a peak contraction in the abs and obliques.
  3. Inhale as you lower back down with control, returning to the hovering start position without letting your limbs touch the floor.
  4. Alternate sides for each repetition, maintaining a rhythmic but controlled tempo.

Form checklist

  • Keep your lower back glued to the floor during the lowering phase.
  • Rotate through the ribcage to ensure the obliques are driving the twist.
  • Keep the non-working leg straight and hovering just above the mat.
  • Avoid pulling on your neck; lead the movement with your chest and shoulders.

Pro tips

  • Think about bringing your shoulder to the opposite knee rather than just your elbow to maximize trunk rotation.
  • Maintain a 'hollow body' position throughout the entire set to keep the rectus abdominis under constant load.

Make it harder

  • Hold a light medicine ball or weight plate between your hands to increase resistance.
  • Slow the eccentric (lowering) phase to a 3-second count to increase time under tension.
