Procedure

Procedure

  1. Assess Current Volume and Frequency

    • Review the user's current training history and preferences using get_user_history and get_user_preferences.
    • Identify the current frequency per muscle group. If frequency is only 1x per week, prepare to transition to a 2x-3x weekly frequency.

  2. Determine the Split Framework

    • Based on the user's available training days, select an evidence-based framework:
      • 3 days/week: Full Body (Every group hit 3x).
      • 4 days/week: Upper/Lower Split (Every group hit 2x).
      • 6 days/week: Push/Pull/Legs (Every group hit 2x).
    • Target a weekly volume of 10–20 challenging sets per muscle group for hypertrophy, or 6–12 sets for pure strength.

  3. Optimize Exercise Pairings

    • Apply pairing strategies within the workouts to manage fatigue:
      • Agonist-Antagonist: Pair push/pull movements (e.g., Bench Press and Rows) to maintain power and save time.
      • Same Muscle Group: Pair exercises (e.g., Squats and Leg Extensions) only as "finishers" at the end of a session to increase metabolic stress.
      • Unrelated Groups: Pair primary lifts with low-fatigue movements (e.g., Overhead Press and Calves) for maximal strength on the primary lift.

  4. Build the Weekly Plan

    • Use find_exercise_candidates to select movements appropriate for the chosen pairings.
    • Use plan_week to distribute the workouts across the week, ensuring at least 24–48 hours of recovery for full-body routines or 72 hours for PPL sessions.
    • Ensure "junk volume" is avoided by capping per-session muscle group volume and distributing it across multiple days instead.

  5. Refine and Finalize

    • Use create_workout to populate the specific exercise sets and pairings.
    • Advise the user that while 10–20 sets is the standard range, they should monitor recovery and adjust toward their individual Maximum Recoverable Volume (MRV).
