One-Arm Cable Preacher Curl

1. General Description The One-Arm Cable Preacher Curl is a strength training exercise that targets the biceps brachii muscle, the muscle located in the upper arm that flexes the elbow. By focusing on one arm at a time, this exercise provides a more concentrated and unilateral approach to bicep training. It utilizes a cable machine and a preacher bench, combining the benefits of isolation and constant tension provided by the cable pulley system.

2. How to Perform the Exercise Performing the One-Arm Cable Preacher Curl involves the following steps:

  1. Setup: Position a preacher bench in front of a low pulley cable machine. Attach a single handle to the low pulley.

  2. Position: Sit on the preacher bench with your chest against the padding and the working arm’s armpit over the top of the pad. Grasp the cable handle with an underhand grip (palms facing upward).

  3. Execution: While keeping your upper arm stationary, exhale and curl the weight up by flexing at the elbow. Continue to raise the weight until your bicep is fully contracted and the handle is at shoulder level. Hold the contracted position for a brief moment.

  4. Return Phase: Inhale and slowly begin to bring the handle back to the original position as your arm is extended again.

  5. Repeat: Perform the recommended number of repetitions with one arm before switching to the other arm.

3. Good Sides There are several benefits of incorporating the One-Arm Cable Preacher Curl into your training regimen:

  1. Isolation and Focus: The preacher bench helps isolate the biceps by restricting the movement of the elbow and shoulder, ensuring that the bicep does most of the work.

  2. Balanced Development: Since you’re working one arm at a time, you can correct any muscular imbalances between arms.

  3. Constant Tension: The cable provides a constant tension throughout the movement, which can lead to improved muscle growth and strength.

4. Downsides Despite its many benefits, there are a few downsides to consider:

  1. Limited Compound Engagement: This exercise is an isolation move, so it doesn’t engage many other muscles or burn as many calories as compound exercises.

  2. Equipment Dependency: You need both a preacher bench and a cable machine, so it’s not always a convenient exercise for those without access to a well-equipped gym.

5. Alternative Exercises If you don’t have access to the required equipment, or want to add some variety, there are alternative exercises:

  1. Dumbbell Preacher Curl: This exercise is similar, but uses a dumbbell instead of a cable. It does not provide constant tension, but still allows for effective isolation.

  2. Incline Dumbbell Curl: If you don’t have a preacher bench, an incline bench can be used for a similar effect. The exercise is performed with dumbbells and focuses on the biceps.

  3. Hammer Curl: This exercise targets the biceps and the brachialis, a muscle of the upper arm. It can be performed with dumbbells and does not require a bench or cable machine.

6. Conclusion The One-Arm Cable Preacher Curl is a powerful exercise for bicep development, offering a unique blend of isolation and constant tension. While it does have its downsides, such as equipment dependency and limited compound engagement, it’s a valuable addition to any upper-body or arm-specific workout routine. Like any exercise, it’s most effective when used as part of a balanced and varied workout regimen.
