How many holes should the safety racks have?

The correct choice indicates that safety racks should have 10 holes. This standard is established to provide an adequate range of adjustment for lifters, accommodating various heights and preferences for optimal safety during lifts. Having 10 holes allows referees and lifters to ensure that the lifting bar is positioned at an appropriate height, which is crucial for safety, especially during attempts with heavy weights.

This design promotes versatility, enabling athletes of different sizes to set the bars precisely where needed to prevent injury and maximize performance. Additionally, a greater number of holes also means that adjustments can be made with finer granularity, which can be beneficial for achieving the perfect lift setup.
