How Iridium Programs This

Iridium tracks the Bridge Walk as a shortened-position hamstring movement, distinguishing its specific fatigue profile from lengthening exercises like deadlifts to prevent range-specific overuse. The AI often programs this as a low-systemic-fatigue accessory when your 7-day history shows high workout loads but remaining capacity for local muscle volume. Iridium uses your RPE feedback on these bodyweight sets to gauge intensity and determine if the duration needs to increase to effectively stimulate the muscle.

Form Cues

Lift your hips until they align with your shoulders and knees
Brace your core tightly to prevent your lower back from arching
Walk your feet out using short, controlled steps on your heels
Squeeze your glutes continuously throughout the movement
Keep your pelvis level and stable as you move your legs

Don't

Don't let your hips sag towards the floor as you walk out
Don't allow your hips to rock side-to-side with each step
Don't overarch your lower back to compensate for weak glutes
Don't take large strides that compromise your stability
Don't rush the movement; speed reduces muscle activation

Common Mistakes

Sagging hips
Rocking pelvis side-to-side
Hyperextending the lower back
Walking out too far too soon
Relaxing the core

Muscles Worked

This exercise primarily targets the glutes and hamstrings, requiring them to maintain hip extension against gravity while the leverage changes dynamically. It also heavily recruits the erector spinae and deep core muscles to stabilize the pelvis and prevent rotation during the walking motion.
