Sicilian Roll Up

  • Intermediate
  • Compound
  • Rep-based
  • Waist

The Sicilian Roll Up is an advanced core variation that increases the lever length of the torso by keeping the arms extended vertically, significantly intensifying the demand on the rectus abdominis and obliques compared to a standard crunch.

Setup

  1. Lie flat on your back with your legs fully extended and feet flexed.
  2. Extend your arms straight up toward the ceiling, perpendicular to your torso.
  3. Tuck your chin slightly and press your lower back firmly into the floor to engage your deep core.

How to do it

  1. Exhale and begin 'peeling' your spine off the mat, keeping your arms pointed straight up toward the ceiling throughout the entire ascent.
  2. Continue rolling up one vertebra at a time until you are sitting tall with your arms directly overhead.
  3. Inhale at the top, then exhale as you slowly articulate your spine back down to the mat, starting from the tailbone.
  4. Maintain a controlled 3-second tempo for both the ascent and descent, ensuring no momentum is used.

Form checklist

  • Keep your heels glued to the floor; do not let them lift as you roll up.
  • Ensure your arms stay vertical (pointing at the ceiling) rather than swinging forward for momentum.
  • Move slowly through the 'sticky point' in the middle of the movement.
  • Maintain a smooth, rounded spine (C-curve) during the transition to protect the lower back.

Pro tips

  • Imagine your spine is a bicycle chain being laid down link by link to maximize segmental control and abdominal recruitment.
  • Squeeze your inner thighs together to help stabilize the pelvis and prevent the hip flexors from taking over the movement.

Make it harder

  • Hold a light weight plate or dumbbell between your hands while keeping the arms locked vertically.
  • Slow the eccentric (lowering) phase down to 6-8 seconds to increase time under tension.
