Selecting the correct exercise ball size is essential for maintaining proper posture, maximizing workout effectiveness, and minimizing the risk of injury. An appropriately sized ball allows for optimal alignment of the spine, hips, and knees, ensuring that exercises are performed with the correct form.
Exercise balls, also known as Swiss balls or fitness balls, come in various sizes, typically ranging from 45 to 85 centimeters in diameter. The appropriate size depends on the user’s height and inseam length. A properly sized ball allows the user to sit with their feet flat on the floor, knees bent at a 90-degree angle, and thighs parallel to the floor.
