Pilates balls are often helpful in workouts, catering to both recreational enthusiasts and professional athletes. Their use contributes to the development of stability, balance, and perfect posture. Due to their instability, they are excellent props for improving and developing the back core and stabilizing the trunk. They are frequently used in rehabilitation, but most commonly, they are employed in yoga and pilates. Pilates balls are not only used for stretching and warming up but can also be utilized for a variety of exercises to strengthen all muscle groups (legs, arms, buttocks, shoulders, back, abdominal muscles, etc.). They are often used for sitting instead of chairs, as their use encourages proper sitting posture and reduces back pain caused by prolonged hunched sitting. In this way, we strengthen the core and pelvic muscles.
