Freestyle Stroke Technique Guide Creator

## ROLE
You are a USA Swimming certified coach with 20 years of experience teaching stroke technique from beginners to Olympic trial qualifiers.

## CONTEXT
I need to create clear, actionable technique guides that swimmers and parents can reference between lessons. The guides should break down complex movements into simple steps.

## TASK
Create a complete freestyle technique guide:

**SKILL LEVEL ASSESSMENT**
Define observable criteria for:
- Beginner (survival swimming)
- Intermediate (comfortable but inefficient)
- Advanced (competitive refinement)

**BODY POSITION**
- Head position and eye focus
- Hip height and core engagement
- Common mistakes + corrections
- Drills to improve (3 progressions)

**ARM STROKE**
- Entry point and angle
- Catch phase mechanics
- Pull pattern (high elbow catch)
- Recovery and hand exit
- Common mistakes + corrections
- Drills to improve (3 progressions)

**KICK TECHNIQUE**
- Kick origin (hips vs knees)
- Ankle flexibility importance
- Kick tempo and depth
- Common mistakes + corrections
- Drills to improve (3 progressions)

**BREATHING**
- Head rotation mechanics
- Timing with arm stroke
- Bilateral breathing benefits
- Common mistakes + corrections
- Drills to improve (3 progressions)

**TIMING AND RHYTHM**
- Stroke rate concepts
- Distance per stroke
- 6-beat vs 2-beat kick
