Procedure

  1. Assess Developmental Stage and Foundation

    • Inquire if the user has reached puberty to differentiate between neurological and morphological goals.
    • Verify that they have access to qualified adult supervision for all sessions.
    • Ensure the user understands the "technique-first" philosophy: perfect form with bodyweight or unweighted bars must precede added resistance.

  2. Calculate Nutritional and Hydration Baselines

    • Use compute_protein_target to establish a range of 10% to 30% of daily calories, ensuring a distribution of approximately 0.4g/kg per meal.
    • Use compute_water_intake to set hydration baselines focused on thermoregulation.
    • Advise against restrictive dieting; emphasize caloric adequacy to support growth and prevent Relative Energy Deficiency in Sport (RED-S).

  3. Design the Training Schedule

    • Use create_week to schedule 2–3 non-consecutive training days per week.
    • Ensure session duration is set between 20–60 minutes.
    • Include a mandatory 10–15 minute dynamic warm-up and a cool-down period.

  4. Structure Workouts and Exercises

    • Use create_workout to build sessions featuring 1–3 sets per exercise.
    • Set the repetition range strictly between 8–15 repetitions.
    • Prioritize fixed-path machines for beginners to provide external stability, transitioning to free weights only as coordination and stability improve.
    • Prohibit 1-Repetition Maximum (1RM) testing; focus on repetition-based progress.

  5. Implement Linear Progression Logic

    • Create a note using create_note outlining the "Hierarchy of Progression" for the user:
      1. Technique: Master movement with zero/minimal load.
      2. Volume: Increase reps from 8 up to 15 within the same weight.
      3. Load: Only increase weight once 3 sets of 15 reps are completed with perfect form.

  6. Monitor and Support

    • Encourage the user to prioritize variety and ensure this program supplements, rather than replaces, 60+ minutes of daily moderate-to-vigorous physical activity.
    • Use create_note to document baseline measurements and technical milestones rather than absolute weight lifted.
