Get an AI coach that uses this skill

FitnessGrid is an AI coach that plans your week and adapts as you go. Install strength and conditioning for runners and your coach will follow this protocol every week, learn from what you actually do, and adjust on the fly.

  • Your coach builds the week from this skill
  • Adapts to your actual progress, not a static template
  • Free to start — no credit card, ~60 seconds to set up

Procedure

  1. Initial Assessment and Baseline

    • Review the user's running experience and current training phase using get_user_history.
    • Determine if the user is in an off-season/base phase or approaching a competition to determine the starting Phase (I, II, or III).
    • If the user is new to strength training, always begin with Phase I.

  2. Phase I: Anatomical Adaptation (Weeks 1–4)

    • Objective: Build movement proficiency and connective tissue resilience.
    • Frequency: Schedule 2–3 sessions per week.
    • Prescribe 2–3 sets of 12–15 repetitions.
    • Exercise Selection:
      • Single-leg stability: Split squats or single-leg RDLs.
      • Core stability: Planks or dead-bugs.
      • Ankle/Calf: Weighted calf raises (slow tempo).

  3. Phase II: Maximal Strength (Weeks 5–12)

    • Objective: Improve Running Economy (RE) and neuromuscular efficiency via heavy loads.
    • Frequency: Maintain 2–3 sessions per week.
    • Intensity: High (80%+ 1RM). Use compute_one_rep_max if necessary to calibrate loads.
    • Volume: 3–5 sets of 4–8 repetitions with long recovery periods.
    • Exercise Selection:
      • Compound lifts: Back squats, deadlifts, weighted lunges.
      • Posterior chain: Nordic hamstring curls or glute-ham raises.

  4. Phase III: Explosive Power & Stiffness (Weeks 13–20)

    • Objective: Increase Rate of Force Development (RFD) and leg-spring stiffness.
    • Frequency: 2 sessions per week to allow for higher running intensity.
    • Volume: 3–5 sets of 3–6 repetitions with maximum intent.
    • Exercise Selection:
      • Plyometrics: Pogo hops (for ankle stiffness), box jumps, bounding.
      • Ballistics: Kettlebell swings or jump squats.

  5. Programming Constraints & Integration

    • Interference Effect Management: Advise the user to separate high-intensity running and high-intensity strength sessions by 6 to 24 hours.
    • Body Mass: Inform the user that evidence suggests this protocol improves performance without significantly increasing body mass or VO2 max.
    • Mechanical Clarification: Remind the user that while S&C improves energy economy, specific gait changes (like cadence or overstriding) require separate gait retraining interventions.

  6. Modification and Progression

    • At the end of each phase, evaluate the user's readiness to progress based on consistency and perceived exertion.
    • Use create_workout to update the user's schedule as they transition between phases.
