Procedure

1. Assess and Onboard:

   • Use get_user_preferences to determine current water comfort and access to a pool.
   • Explain the "Technical Progression Model": focusing on reducing drag (hydrodynamics) is prioritized over power, as drag increases exponentially with speed.

2. Phase 1: Stability & Balance (Weeks 1–2):

   • Goal: Establish horizontal body position to prevent sinking hips.
   • Week 1 (Breath & Buoyancy): Create workouts using create_workout focusing on Bobbing (nose exhalation) and Front/Back floating.
     • Cues: "Eyes on the floor" for neutral spine; "Suck in like putting on tight jeans" for core engagement.
   • Week 2 (Body Alignment): Add Streamline glides and 6-beat kick with a kickboard.
     • Cues: "Swim downhill" to press the chest down and lift legs.

3. Phase 2: Propulsion Basics (Weeks 3–4):

   • Goal: Introduce the arm cycle while maintaining body axis.
   • Week 3 (The Catch & Pull): Schedule Catch-up drills.
     • Cues: "Reach for the far wall" to maximize length; "Roll your arm over a big yoga ball" for a high elbow catch.
   • Week 4 (Rotation): Add side-lying kick drills (one arm extended, rotating from hip).
     • Cues: "Rotate from the hips, not the shoulders."

4. Phase 3: Coordination & Breathing (Weeks 5–6):

   • Goal: Integrate bilateral breathing without losing alignment.
   • Week 5 (Rhythmic Breathing): Focus on Single-arm freestyle breathing to the side every stroke.
     • Cues: "Hum into the water" (continuous exhalation) to prevent anxiety.
   • Week 6 (Full Integration): Prescribe 25m intervals focusing on maintaining streamline during the breath.
     • Cues: "One goggle in the water" to prevent over-rotation.

5. Phase 4: Endurance & Refinement (Weeks 7–8):

   • Goal: Increase volume (400–1,200 yards) while preventing technique decay.
   • Week 7 (Interval Pacing): Set 4 x 50m intervals (30s rest).
     • Cues: "Find the glide" to use momentum.
   • Week 8 (Distance): Scale to 100m–200m steady swims.
     • Cues: "Quiet the water" for clean hand entry.

6. Implementation Guidelines:

   • Ensure sessions last 20–40 minutes to build aerobic capacity.
   • Use create_note to record the "Drag Equation" principle: head down and hips up are the most critical factors for beginner speed.
   • Monitor for "downward pushing" (Newton's Third Law): Remind users to push water backward to move forward, rather than pushing down which sinks the legs.

7. Review:

   • Use plan_week at the start of each phase to adjust volume based on the user's recovery and technique consistency.
