Biomechanical cues verified by the PlanWorkouts Science Review Board under CSCS editorial oversight; see our editorial standards.

The Cable One Arm Lateral Raise is a targeted isolation shoulders movement designed to train the Delts with direct engagement of the Triceps.

Single-joint abduction or horizontal abduction isolating the lateral, anterior, or posterior deltoid heads through a curved arc of motion. Executing this with strict form maximizes muscle fiber recruitment while protecting joint structures.

Target Muscle Activation

Delts — Agonist
Traps — Synergist
Stabilizers — Core & Kinetic Chain

Training the lateral raise one arm at a time on a cable keeps constant tension on the working side through the whole arc, while the free hand can brace against the machine for stability. It's a good option for isolating a weaker shoulder or simply focusing harder on mind-muscle connection than a two-arm raise allows. Leading with the elbow rather than the hand keeps the delt doing the work instead of the traps.

How to Do the Cable One Arm Lateral Raise

  1. Stand with your feet shoulder-width apart, facing the cable machine.
  2. Hold the cable handle with one hand, palm facing down, positioned far enough from the machine that there is tension on the cable.
  3. Keep your arm straight and slowly raise it out to the side until it is parallel to the ground.
  4. Pause briefly at the top, then slowly lower your arm back down to the starting position.
  5. Repeat for the desired number of repetitions, then switch sides.

Biomechanical & Joint Load Cues

Single-joint abduction or horizontal abduction isolating the lateral, anterior, or posterior deltoid heads through a curved arc of motion.

Common Mechanical Mistakes & Form Errors to Avoid

  • Shrugging the Trapezius: Elevating the shoulder blades to hike the weight up shifts mechanical tension off the lateral deltoid onto the upper traps.
  • Leading with Hands Instead of Elbows: Lifting wrists higher than elbows rotates the shoulder into internal impingement; keep elbows level with or slightly above wrists.
  • Using Heavy Body English: Swinging the torso to launch heavy dumbbells turns an isolation exercise into a sloppy momentum drill with minimal delt tension.

Proper Breathing Patterns & Core Engagement

Exhale smoothly as the weights are raised to shoulder height; inhale during the controlled 2-3 second descent.

Injury Modification & Joint Safety

If experiencing subacromial pinch during lateral raises, angle arms 15–30 degrees into the scapular plane (slightly forward of direct sideways). If joint irritation persists, immediately stop and substitute this movement with another exercise from the Shoulders exercises category.

Muscles Worked

The Cable One Arm Lateral Raise primarily targets the Delts, with Traps as the primary synergist muscle group, along with the Triceps.

FAQ

What muscles does the Cable One Arm Lateral Raise work?
The Cable One Arm Lateral Raise primarily targets the delts as the primary agonist. Synergist assistance is provided by the traps along with the triceps. Maintaining strict biomechanical alignment ensures maximal tension remains focused on the intended muscle fibers rather than shifting to surrounding stabilizer joints.
What equipment do I need for the Cable One Arm Lateral Raise?
The Cable One Arm Lateral Raise is performed using a cable. Ensure all equipment is securely positioned with collars or safety pins locked before loading working sets. If you train in a home gym or minimal setup, explore our equipment-free and resistance band alternatives below.
What is the most common form mistake on the Cable One Arm Lateral Raise?
The most frequent error is shrugging the trapezius: Elevating the shoulder blades to hike the weight up shifts mechanical tension off the lateral deltoid onto the upper traps.. Controlling the 2 to 3-second eccentric lowering phase ensures maximal hypertrophic stimulus while shielding connective tissue.
How many sets and reps should I perform on the Cable One Arm Lateral Raise?
For muscle growth and density, execute 3 to 4 working sets of 10 to 15 controlled repetitions with 60 seconds rest, emphasizing a deep stretch and deliberate peak contraction on every rep.
What's a good alternative to the Cable One Arm Lateral Raise?
If you don't have access to a cable, the Left Hook. Boxing targets the same delts using body weight instead. This alternative replicates the same joint angle and movement plane while allowing you to train effectively with different available gear. You can also substitute it seamlessly in our free Workout Plan Builder.
