How Iridium Programs This

Iridium tracks your repetition performance relative to body weight to determine progressive overload without external load. This data feeds into your glute volume calculations, ensuring you hit Minimum Effective Volume targets while avoiding the high systemic fatigue of heavier leg exercises. Iridium may prioritize this movement when your 7-day history indicates your lower back or central nervous system requires lower-impact programming.

Form Cues

Start on all fours with hands directly under shoulders
Brace your core to keep your back completely flat
Squeeze your glute to drive your heel toward the ceiling
Keep your hips square to the floor throughout the rep
Lower the leg slowly to control the eccentric phase

Don't

Don't arch your lower back to lift the leg higher
Don't use momentum to swing the leg upward
Don't rotate your hips open to the side
Don't let your elbows bend or weight shift excessively

Common Mistakes

Hyperextending the lumbar spine
Opening the hips sideways
Using momentum instead of muscle
Insufficient range of motion

Muscles Worked

This exercise primarily isolates the gluteus maximus to build shape and strength in the posterior chain without loading the spine. It also engages the hamstrings as secondary movers and relies heavily on the core and obliques to maintain a neutral spine and pelvic stability during the movement.
