The cable Superman curl is a floor-based exercise that combines a Superman back extension with a biceps curl performed against cable resistance. Lying face down with the arms extended toward a low pulley, you lift the chest, arms, and legs into a Superman position before curling the handle toward your shoulders. The primary work falls on the erector spinae and glutes from the extension portion, with the biceps and rear deltoids engaged secondarily during the curl, making this a light-load, control-focused compound movement rather than a heavy strength builder.
Muscles Targeted
- Primary: Erector spinae (lower back), glutes
- Secondary: Biceps brachii, rear deltoids
- Tertiary: Hamstrings, core stabilizers
Starting Position
Set a low pulley with a single handle attachment at floor level. Lie face down on a mat a few feet in front of the machine, arms extended straight overhead toward the pulley, gripping the handle with a neutral or palms-down grip. Keep your legs straight and together with toes pointed, and your neck in a neutral position with your gaze down at the floor.
Execution Steps
- Brace your glutes and lower back before initiating any movement
- Lift your chest, arms, and legs off the floor simultaneously, extending through the hips and spine into the Superman position
- Hold the extended position momentarily once you reach a comfortable range, without hyperextending the lower back
- Bend your elbows and curl the handle toward your shoulders, keeping your upper arms improved
- Squeeze briefly at the top of the curl, maintaining the back extension throughout
- Extend your arms back out, then lower your chest, arms, and legs together back to the floor to complete the rep
Form Cues
- Extend before you curl: Establish the Superman position fully before adding the arm movement
- Keep your gaze down: Looking up strains the cervical spine and breaks proper alignment
- Squeeze the glutes to initiate: This drives the extension rather than relying on the lower back alone
- Move both phases with control - this is not a movement for speed or momentum
- Reset fully to the floor between reps rather than hovering
Common Mistakes
- Curling before establishing the extension: This skips the primary back-and-glute benefit of the movement. Lift into the Superman position first, then curl.
- Hyperextending the lower back: Lifting too high strains the spine unnecessarily. Rise only to a comfortable, controlled range.
- Using momentum or jerking upward: This reduces muscular control and increases injury risk. Move deliberately through both the extension and curl.
- Using too much resistance: Heavy weight prevents a full, controlled extension and curl. Use a light load given the combined spinal and arm demand.
- Looking up during the lift: Cervical hyperextension can strain the neck. Keep your gaze toward the floor throughout.
Variations
- Bodyweight Superman: Removes the cable and curl, isolating the back-extension pattern for beginners
- Superman row: Pulling the elbows back instead of curling shifts emphasis further onto the upper back
- Banded Superman curl: A resistance band substitutes for the cable machine for a portable version
- Stability ball Superman: Performing the extension over a stability ball adds an instability challenge
- Roman chair back extension: An alternative posterior-chain exercise without the arm-curl component
Tips for Progression
- Master the bodyweight Superman hold for 20-30 seconds before adding cable resistance
- Start with a very light cable weight given the combined spinal-extension and curl demand
- Increase the hold time at the top of the extension before adding load
- Add reps before increasing resistance, progressing toward 12-15 controlled reps
Training Notes
Program the cable Superman curl once or twice per week as a posterior-chain and core finisher, using light resistance for 2-3 sets of 10-12 controlled reps with 60 seconds of rest between sets. It fits well at the end of a lower-back or arm-focused session rather than as a primary strength movement, given its emphasis on control over load.
