How Iridium Programs This

Iridium treats the Ski Erg as both a metabolic tool and a mechanical hip-hinge movement, cross-referencing your recent lower back and upper trapezius workload against your 7-day history. If these muscle groups are fatigued from recent heavy lifting, Iridium adjusts the duration and intensity to ensure you don't exceed your Maximum Recoverable Volume on what is ostensibly a cardio exercise.

Form Cues

Start with your hands high and feet shoulder-width apart
Initiate the pull by driving your hips back firmly
Crunch your abs down as you pull the handles
Extend your arms past your thighs at the bottom
Rise back up smoothly using your glutes

Don't

Don't squat down with your knees forward
Don't pull exclusively with your arms
Don't keep your arms completely straight
Don't cut the range of motion short at the top

Common Mistakes

Squatting instead of hinging at the hips
Using only the shoulders to move the weight
Leaving the core relaxed during the pull
Letting the handles snap back up uncontrolled

Muscles Worked

This exercise is a total-body power generator that relies heavily on the General Core and lats to transmit force, while the Anterior Deltoids and Trapezius assist in the arm cycle. The movement is driven by the posterior chain, requiring the glutes and hamstrings to stabilize the powerful hip hinge involved in every stroke.
