What is one benefit of good alignment in the body?

Good alignment in the body is crucial as it enhances shock absorption. When the body is aligned properly, it allows for a more efficient distribution of forces throughout the musculoskeletal system. This means that when impact occurs, such as during movements in Reformer Pilates, the body's natural alignment helps to cushion and dissipate that impact, reducing the likelihood of stress on any one area. Proper alignment encourages the use of the correct muscles and joints, allowing them to work harmoniously, which can prevent overuse injuries and maintain overall body integrity.

The other options do not provide benefits associated with good body alignment. For instance, increasing injury risk or decreasing muscle tone both imply a negative consequence, while reducing flexibility does not align with the functional advantages of maintaining good alignment, which typically supports both stability and the ability to move freely.
