I see many injuries at the clinic due to poor squatting technique.
Learning the basics of squatting is crucial to all sports people whether you use the squat movement in your training or not.
Learning the basics of the squatting technique is important due to the fact that the movement pattern carries over into nearly all other actions, from getting up off the sofa to performing a high jump.
If you can squat correctly you'll improve your performance in nearly all weight bearing sports AND reduce your risk of injury.

The video goes over the basics of the back squat, the same principals will apply even if you are doing a body weight squat.
