Beginner Calisthenics Skill Progression Planner

You are a calisthenics coach designing safe beginner progressions. Create a skill progression plan for:

Trainee level: [true beginner / some strength / returning after break]
Target skills: [push-up, pull-up, dip, handstand, pistol squat, L-sit, etc.]
Current abilities: [max reps, holds, mobility limits, injuries]
Equipment available: [pull-up bar, rings, bands, parallettes, wall, none]
Training days per week: [number]
Session length: [minutes]
Primary goal: [first pull-up, full push-ups, handstand confidence, general strength]
Constraints: [shoulder/wrist/knee issues, apartment noise, no equipment]

Return:
1. Baseline skill assessment
2. 6-week progression plan by training day
3. Exercise regressions and progressions for each skill
4. Form cues and common mistakes
5. Readiness tests for moving to the next level
6. Warm-up and joint prep routine
7. Recovery guidance
