Procedure

1. Assess and Configure Preferences:

   • Confirm the user's primary goal is lower body hypertrophy with waist maintenance.
   • Use compute_protein_target to establish a baseline of 1.7–2g/kg of body weight to support muscle repair.
   • Use remember to store the preference for avoiding weighted oblique work and prioritizing "cinched" waist aesthetics.

2. Select Lower Body Movements by Vector:

   • For each lower body session, use find_exercise_candidates to select:
     • Vertical Hip Extension (Stretched): 1–2 exercises such as squats, Romanian deadlifts, or lunges.
     • Horizontal Hip Extension (Shortened): 1–2 exercises such as barbell hip thrusts or glute bridges.
     • Unilateral/Activation focus: 1 exercise such as step-ups for high GMax activation.
     • Lateral/Rotary focus: 1 exercise such as seated or cable hip abductions for gluteus medius fullness.

3. Implement Waist-Narrowing Core Strategy:

   • Audit current core exercises. Replace any weighted side-bends or weighted spinal twists.
   • Integrate Static Stability movements: planks and dead-bugs to develop functional strength without bulk.
   • Include Transversus Abdominis (TVA) training: prescribe "stomach vacuums" to improve the "cinched" appearance.

4. Optimize Stability for Intensity:

   • To allow high-intensity leg training without excessive external oblique/rectus abdominis bracing, incorporate machine-based movements.
   • Use create_workout to suggest substituting heavy free-weight compound lifts with Hack Squats or Leg Presses when the goal is purely muscular failure with minimal core thickening.

5. Program Parameters:

   • Volume: Schedule 3–6 sets per exercise.
   • Proximity to Failure: Ensure sets are performed close to failure across various loading zones to maximize hypertrophy.
   • Frequency: Distribute the identified movements across multiple weekly sessions to ensure adequate recovery and total volume.

6. Progressive Overload Tracking:

   • Monitor systematic increases in load, repetitions, or range of motion for all prioritized lower body movements to drive continued adaptation.
