How many cm should the increments be on a squat rack?

The correct increment for adjusting the squat rack is 2.5 cm. This measurement is established by the International Powerlifting Federation (IPF) to allow for precise adjustments during competitions. Using smaller increments like 2.5 cm facilitates the ability of lifters to make minute adjustments to the bar height, which can be crucial for an athlete's performance and comfort. Each lifter may have specific preferences for bar height based on their individual body mechanics and technique, so having 2.5 cm increments helps accommodate these variations effectively.

Larger increments, such as 5 cm or 10 cm, would limit the adjustability and could prevent lifters from finding the optimal position for their squat. In competitions, precision in equipment setup is of utmost importance, and the 2.5 cm increment standard encourages consistency and fairness across all lifts.
