How Iridium Programs This

Freestyle swimming places significant load on the latissimus dorsi and trapezius, distinguishing it from lower-body dominant cardio. Iridium factors this specific exertion into your per-muscle recovery scores to ensure you do not exceed your Maximum Recoverable Volume for the back. If your 7-day history indicates high fatigue from swimming, the AI will adjust the volume of upcoming pulling exercises to allow for adequate restoration.

Form Cues

Keep your head neutral with eyes looking down at the bottom of the pool
Rotate your body gently from the hips with each arm stroke
Extend your arm fully forward before catching the water
Breath rhythmically to the side without lifting your head completely out of the water
Maintain a steady, relaxed flutter kick originating from the hips

Don't

Don't lift your head straight up to breathe
Don't let your hips sink significantly below the water surface
Don't cross your hand over the midline of your body during the entry
Don't kick excessively from the knees
Don't slap the water with your palms

Common Mistakes

Lifting head forward to breathe
Sinking hips and legs
Crossing the midline with hands
Excessive knee bending in kick
Short, choppy arm strokes

Muscles Worked

This exercise is a powerhouse for the posterior chain, primarily targeting the Latissimus Dorsi and Upper Trapezius to generate pulling power through the water. Secondary emphasis falls on the core and glutes to maintain a streamlined horizontal body position, while the triceps and shoulders assist in the catch and recovery phases of the stroke.
