What are the 3 keys to proper squat technique?

The three keys to proper squat technique are:1. Keeping your back straight and your chest up: This helps to maintain proper alignment and balance during the squat, and prevents your back from rounding or your chest from collapsing.2. Lowering your body down into the squat while keeping your knees behind your toes: This helps to ensure that you are using your hips and glutes to drive the movement, rather than your knees, which can help to prevent injury and improve the effectiveness of the exercise.3. Pushing through your heels and standing back up: This helps to engage your glutes and hamstrings, and also helps to maintain proper balance and stability during the squat.
