In Pilates, this exercise, often referred to in crossword puzzles by its numerical name, is a foundational movement focusing on core stabilization and breath control. It involves sustained abdominal engagement while pumping the arms rhythmically, inhaling and exhaling in a specific 5-count pattern.
This exercise strengthens the deep abdominal muscles, improves breathing capacity, and enhances overall core stability. Historically, its unique breathing pattern and controlled movements were central to Joseph Pilates’ original method. It serves as a warm-up for many other exercises, preparing the body for more demanding movements and establishing a mind-body connection crucial for successful Pilates practice.
