Straight-Arm Lat Pulldown (Cable)

A cable isolation exercise that targets the lats by performing shoulder extension with fixed, straight arms. It effectively isolates the back muscles without fatiguing the biceps.

How Iridium Programs This

Iridium programs this isolation movement to add necessary volume to the Latissimus Dorsi without adding fatigue to the biceps. If your recent workout history shows heavy compound pulling that likely taxed your arms, the algorithm selects this exercise to ensure your back still meets its volume landmarks. Progression is managed by tracking RPE trends to ensure tension remains on the lats rather than using momentum to move heavier loads.

Form Cues

Do
  • Hinge slightly at the hips with knees soft to stabilize your torso
  • Keep your elbows locked or with a very slight, fixed bend throughout the rep
  • Depress your shoulder blades before initiating the pull
  • Drive the bar down towards your thighs in a smooth arc
  • Squeeze your lats hard at the bottom position
Don't
  • Don't bend and extend your elbows during the movement (turning it into a tricep press)
  • Don't use momentum to swing the weight down
  • Don't let your shoulders shrug up towards your ears
  • Don't round your lower back or lose core tension

Common Mistakes

  • Turning the movement into a triceps pushdown
  • Using excessive momentum
  • Shrugging shoulders upward
  • overarching the lumbar spine
  • Gripping the bar too tightly

Muscles Worked

This exercise primarily targets the latissimus dorsi by utilizing pure shoulder extension, removing the biceps from the equation which limits many other back exercises. It also heavily recruits the long head of the triceps for stability, the posterior deltoids, and the core to maintain a rigid torso position.
