What part of the body does the powerhouse mainly involve?

The powerhouse in Pilates refers primarily to the core area, which includes the abdominal muscles, lower back muscles, pelvic floor, and the muscles surrounding the hips. This area is essential for stabilizing the body and provides the strength and support needed for both postural alignment and movement. Engaging the powerhouse effectively allows for better control and efficiency of movement, which is a fundamental principle of Pilates practice. By focusing on this central area, practitioners can enhance their balance, coordination, and overall strength, leading to improved performance in various activities and exercises.
