Gym Workout Split Designer

Design an optimal gym training split for me:

**Days I Can Train:** [NUMBER] days per week
**Specific Days Available:** [DAYS - e.g., Mon/Tue/Thu/Fri/Sat]
**Primary Goal:** [GOAL - hypertrophy, strength, athletic performance, body recomposition]
**Training Experience:** [YEARS] years
**Weak Points to Emphasize:** [BODY PARTS]
**Time Per Session:** [MINUTES] minutes
**Preferred Training Style:** [e.g., traditional bodybuilding, powerlifting, functional, hybrid]

Please recommend:
1. **Optimal Split Type** (PPL, Upper/Lower, Bro Split, Full Body, etc.) with reasoning
2. **Weekly Layout** showing which muscle groups each day
3. **Volume Recommendations** (sets per muscle group per week)
4. **Exercise Selection Framework** for each day:
   - Compound movements
   - Isolation exercises
   - Order of exercises
5. **How to Structure Each Session:**
   - Warm-up approach
   - Working set progression
   - Rest periods by exercise type
6. **When to Change the Split** and signs it's working
