The proper way to squat is as follows: take a nice wide stance with feet hip width apart, and toes pointed straight ahead, sit your butt back as if you are about to sit in a chair and keep all the weight heavy in the heels behind you. If I was to push you, for example, you should fall backwards not forward. A couple of things you need to look out for when performing a squat: make sure your knees do not turn in as you sit back, make sure your toes are not pointed out, make sure your knees do not come over the front toes, make sure your chest is up and does not fall too far over your knees, and make sure your lower back is not arched. If you keep your weight in those heels, your knees will not come over those toes and if you engage your core, your back will not arch. Sometimes with squats, people think it is a contest of how low you can drop down. However, this is not the case as form can be compromised. A squat is one of the best lower body exercises, however if your form is compromised, it can result in muscle imbalances and possibly injury.
