Before initiating a squat, how must a lifter's body be positioned?

The correct positioning of a lifter before initiating a squat is crucial for safety and effective performance. When the feet are shoulder-width apart, it allows for a stable base of support, which is essential for maintaining balance throughout the movement. This position also aligns the lifter's knees over their feet, reducing undue strain on the joints and ensuring proper biomechanics are followed.

Additionally, placing the bar across the upper back ensures that the load is distributed correctly over the shoulders, providing the necessary leverage for the squat. This setup helps engage the core and stabilizes the upper body, which is vital for transferring force effectively from the lower to the upper body during the squat.

Choosing the correct body position enhances the lifter's ability to perform the squat safely and effectively, thereby increasing the likelihood of adhering to the standards set by the International Powerlifting Federation.
