How Iridium Programs This

Iridium treats this as a stability-dependent accessory lift, using sub-muscle-group fatigue tracking to confirm your adductors and glutes are fresh enough for the balance requirements. The AI progresses this bodyweight movement based on RPE trends and rep performance relative to your body weight rather than standard 1RM calculations. If your 7-day history shows substantial leg volume, Iridium may rotate in a more stable variation to ensure the target muscles remain the limiting factor.

Form Cues

Keep light tension on the TRX straps throughout the set
Drive firmly through your front heel to stand up
Hover your back knee just above the floor without touching
Keep your chest lifted and hips square to the anchor point
Track your front knee in line with your second toe

Don't

Don't pull yourself up using your arms
Don't let your front knee collapse inward
Don't rest your back foot on the ground between reps
Don't twist your torso excessively to the side
Don't let the TRX straps go slack

Common Mistakes

Over-relying on arm strength
Touching the back foot down
Rotating hips away from center
Allowing the front knee to cave in
rounding the upper back

Muscles Worked

This exercise primarily targets the quadriceps and gluteus maximus, with a unique emphasis on the gluteus medius and adductors due to the rotational 'curtsy' angle. The TRX straps engage the upper body and core for stability, while the hamstrings act dynamically to control the descent and stabilize the knee.
