Before diving into the specific 23/11/12 routine, it is essential to understand the creator. Katerina Hartlova is a Czech-born fitness instructor, model, and online coach. Unlike many high-intensity trainers, Hartlova focuses on low-impact, high-connectivity movements. Her philosophy revolves around:
Toward the end of a session, the practice transitions into a cooling-down phase. This involves floor stretches like the Pigeon Pose or Butterfly Pose, which target the hips and lower back—areas where many people hold tension. The final and most important posture is Savasana, or Corpse Pose. This period of total relaxation allows the body to integrate the benefits of the practice, leaving the practitioner feeling refreshed and centered.
