Which of the following is a proper technique during a squat movement?

Tracking the knees over the second and third toes is considered a proper technique during a squat movement because it helps ensure that the knees remain aligned with the feet throughout the exercise. This alignment is crucial for maintaining balance and stability while also optimizing the recruitment of the lower body muscles, such as the quadriceps, hamstrings, and glutes. Proper knee tracking minimizes undue stress on the joints and reduces the risk of injury.

In contrast, keeping the feet together can restrict movement and impede balance, making it harder to execute the squat correctly. Leaning forward excessively disrupts the natural alignment of the spine and can lead to strain on the lower back. Raising the heels off the ground shifts the center of gravity and can cause instability, also increasing the risk of injury to the knees and ankles. Therefore, maintaining a good alignment by allowing the knees to track over the proper part of the foot is essential for effective and safe squatting.
