Standing Cable Core Twist

The Standing Cable Core Twist is a functional rotational exercise that targets the obliques and deep core muscles using constant cable tension. It strengthens the torso's ability to generate rotational power and resist external forces, improving athletic performance and spinal stability.

How Iridium Helps

Since rotational power relies heavily on proper fatigue management, the AI analyzes your RPE and previous set performance to adjust cable weight instantly, preventing form breakdown that often leads to lower back strain. By tracking your recovery status and sleep quality, the app determines if you should focus on high-velocity power twists or controlled stability reps for the day. It also learns your specific range of motion comfort, suggesting alternative angles if you have a history of hip or lumbar pain.

Form Cues

Do
  • Stand perpendicular to the cable stack with feet shoulder-width apart
  • Keep your arms straight and locked in front of your chest
  • Initiate the rotation from your hips and torso, not your shoulders
  • Pivot your back foot slightly to allow full hip rotation
  • Control the return phase slowly to resist the cable's pull
Don't
  • Don't bend your elbows to pull the weight close to your body
  • Don't keep your hips stiff or locked in place
  • Don't use momentum or swing the weight uncontrollably
  • Don't let the weight stack touch down between reps
  • Don't hunch your shoulders up towards your ears

Common Mistakes

  • Pulling with the arms instead of the core
  • Rushing the eccentric (return) phase
  • Locking the hips and twisting the knees
  • Using excessive weight that compromises posture
  • Rounding the lower back

Muscles Worked

This exercise primarily targets the internal and external obliques, which are crucial for rotational power and lateral stability. It also heavily engages the rectus abdominis and transverse abdominis to stabilize the spine, while the forearms and shoulders work isometrically to maintain the lever arm.
