How Iridium Programs This

Iridium evaluates the recovery status of your quadriceps and glutes to ensure this cardio session doesn't interfere with your recent or upcoming leg strength work. It monitors your systemic fatigue scores based on sleep and recent load to assign an appropriate RPE target, shifting between steady-state and intervals depending on your redness. The duration is also strictly bounded by your available time constraints to ensure consistent adherence.

Form Cues

Stand tall with your chest lifted and shoulders relaxed to maintain good posture.
Drive down through your heels to engage your glutes and hamstrings effectively.
Actively push and pull the handles to incorporate your upper body.
Keep a slight bend in your knees at all times to avoid locking your joints.
Engage your core slightly to stabilize your spine and prevent excessive swaying.

Don't

Don't lean your weight heavily on the handrails or console.
Don't pedal exclusively with your toes, which can cause numbness.
Don't allow your knees to collapse inward while pedaling.
Don't grip the handlebars tightly, as this increases blood pressure unnecessarily.
Don't rely on momentum to spin the pedals without muscle control.

Common Mistakes

Slouching or rounding the shoulders
Bouncing on the pedals due to low resistance
Putting too much pressure on the toes
Leaning forward onto the console
Passive arms without active pushing/pulling

Muscles Worked

This exercise primarily targets the quadriceps and glutes through the downward driving phase of the pedal stroke, mimicking a running motion without the impact. The hamstrings and calves play a secondary role in the recovery phase of the cycle, while the pushing and pulling action engages the anterior deltoids, chest, and upper back.
