In the squat, what position must the feet be in for a valid lift?

In the squat, the requirement for the feet is that they must remain flat on the ground at all times during the lift. This is crucial because a valid squat is characterized by maintaining proper contact with the surface, which ensures stability and balance. If the lifter's feet come off the ground, even partially, the lift may be deemed invalid since it indicates a lack of control and proper technique.

While other factors regarding foot positioning, such as shoulder-width apart or toes pointing outward, can influence lift technique and individual comfort, the fundamental rule is that both heels and the balls of the feet must stay in contact with the platform throughout the squat. This requirement helps to maintain the integrity of the lift and ensures that all lifters are adhering to the same standard.
