Cable Dead Bug

  • Intermediate
  • Compound
  • Rep-based
  • Waist

This variation uses cable tension to engage the lats and intensify the core's demand for anti-extension stability. It effectively integrates the upper and lower body, forcing the obliques and deep abdominals to work harder to keep the spine neutral.

Setup

  1. Set the cable pulley to the lowest setting and attach a rope handle.
  2. Lie on your back facing away from the machine, with your head approximately two feet from the pulley.
  3. Grasp the rope with both hands and pull it over your chest until your arms are vertical and the weight is suspended.
  4. Raise your legs into a tabletop position with your hips and knees bent at 90-degree angles.

How to do it

  1. Inhale and slowly lower one leg toward the floor while keeping the other leg and both arms perfectly stationary.
  2. Exhale as you return the leg to the starting tabletop position, focusing on pulling through the lower abdominals.
  3. Alternate legs for the next repetition, ensuring the cable remains taut and your arms stay vertical.
  4. Maintain a slow, controlled tempo, taking 3 seconds to lower the leg and 2 seconds to return.

Form checklist

  • Press your lower back firmly into the floor throughout the entire movement.
  • Keep your ribs tucked toward your pelvis to prevent the ribcage from flaring.
  • Ensure the stationary knee remains at a strict 90-degree angle.
  • Keep your arms locked in place over your chest to maintain constant lat engagement.

Pro tips

  • Think about 'shortening' the distance between your belly button and your ribcage to maximize abdominal compression.
  • Imagine you are crushing a grape under your lower back to ensure the spine stays neutral and the deep core is braced.

Make it harder

  • Perform the movement with straight legs to increase the lever length and torque on the core.
  • Hold the cable with only one hand (unilateral) to add a significant anti-rotational challenge for the obliques.
