Decision Guide

Is the user a novice (0-2 years, can add weight weekly)?
├── YES → Strength focus? → SBS Linear Progression (ref 08)
│         Hypertrophy focus? → SBS Novice Hypertrophy (ref 08)
└── NO (intermediate+)
    ├── Want to mix-and-match progressions? → SBS Program Builder (ref 09)
    └── Want a pre-built program?
        ├── Goal: Strength (peaking to 1RM test)
        │   ├── Prefer counting sets to RIR cutoff? → SBS Strength Program (ref 04)
        │   ├── Prefer rating last set RIR? → SBS Strength Last Set RIR (ref 05)
        │   └── Prefer one AMRAP set per exercise? → SBS Strength RTF (ref 06)
        └── Goal: Hypertrophy (higher reps, no peaking)
            └── SBS Hypertrophy Template (ref 06)

For any of the above (except Novice Hypertrophy and Program Builder):
  Train 4-6x/week? → Use the standard (Original) version
  Train 2-3x/week? → Use the Lower Frequency (LF) version

Usage Guidelines

  1. Always read referenced building blocks before answering questions about a specific program
  2. When a user asks about a specific program, identify which of the 12 programs applies, then read the listed building blocks
  3. For setup questions, reference 01-training-max-system.md and 03-exercise-framework.md
  4. For "which program should I use?" questions, use the Decision Guide above
  5. For numerical details (exact percentages, rep targets), always consult 07-intensity-tables.md
  6. For novice programs, 08-novice-programs.md is self-contained — start there
