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
- Set the cable pulley to the lowest setting and attach a rope handle.
- Lie on your back facing away from the machine, with your head approximately two feet from the pulley.
- Grasp the rope with both hands and pull it over your chest until your arms are vertical and the weight is suspended.
- Raise your legs into a tabletop position with your hips and knees bent at 90-degree angles.
How to do it
- Inhale and slowly lower one leg toward the floor while keeping the other leg and both arms perfectly stationary.
- Exhale as you return the leg to the starting tabletop position, focusing on pulling through the lower abdominals.
- Alternate legs for the next repetition, ensuring the cable remains taut and your arms stay vertical.
- 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.
Frequently asked
- What muscles does the cable dead bug work?
- The cable dead bug primarily targets the abs, lats, and obliques, and also works the erector spinae as secondary muscles.
- What equipment do you need for the cable dead bug?
- The cable dead bug uses cable.
- Is the cable dead bug good for beginners?
- The cable dead bug is rated intermediate. Build a base with simpler variations first, then progress to it with light load and strict form.
