How Iridium Programs This

Iridium programs treadmill walking primarily for low-impact conditioning or warmups, as it produces negligible fatigue against your Maximum Recoverable Volume for the lower body. The AI adjusts duration based on your specific time constraints to increase blood flow while ensuring your quadriceps and calves remain fresh for primary lifting movements.

Form Cues

Keep your head up and gaze forward
Engage your core slightly to stabilize the spine
Swing your arms naturally at your sides
Land mid-foot and roll through to your toes
Stay centered on the belt comfortably

Don't

Don't grip the handrails for support
Don't look down at the console or your feet
Don't lean backward or slouch forward
Don't overstride by reaching too far with your heel

Common Mistakes

Holding onto the handrails
Looking down at a phone
Hunching the shoulders
Walking too close to the front console
Taking excessively long strides

Muscles Worked

This exercise primarily engages the quadriceps and calves to manage the rhythmic stepping motion and propulsion. Secondary engagement occurs in the glutes for hip extension and the core muscles, which work isometrically to maintain upright posture and balance on the moving surface.
