How Iridium Programs This

High-stability movements require uncompromised coordination, so Iridium checks your per-muscle recovery status to ensure your core and legs haven't been exhausted by recent training. Since this is a bodyweight accessory lift, the AI tracks your performance relative to your body weight to ensure accurate progressive overload. If your workout time is limited, Iridium may swap this for a bilateral alternative to save the time required for single-leg sets.

Form Cues

Do
  • Stand on the flat side of the balance trainer
  • Press firmly through your standing heel
  • Keep your chest up and shoulders back
  • Control the descent slowly
  • Squeeze your glute at the top of the movement
Don't
  • Don't let your standing knee collapse inward
  • Don't rush the downward phase
  • Don't round your upper back
  • Don't bounce off the floor with the non-working foot
  • Don't look down at your feet

Common Mistakes

  • Knee valgus (caving in)
  • Excessive forward leaning
  • Relying on momentum
  • Uneven hip alignment
  • Lack of core engagement

Muscles Worked

This exercise primarily strengthens the gluteus maximus and hamstrings through a modified single-leg squatting pattern. It places a significant demand on the gluteus medius and core stabilizers to maintain balance on the unstable surface, improving functional stability.
