Bodyweight Squat

Bodyweight Squat:
The bodyweight squat is an easy exercise that can be done anywhere. It works the muscles of the thighs, hips, and buttocks - specifically, the quadriceps, glutes, and hamstrings.
The set up:
-Position your feet slightly wider than shoulder width apart and angled slightly outward.
-Assume a natural curvature of the spine. You will maintain this the entire movement.
The movement:
-Keep your weight distributed across the whole surface of both of your feet, especially your heels.
-Begin the descent downward by allowing your hips to move backwards as if you were going to sit back onto a bench - the knees should primarily stay above your toes and not move forward a lot.
-Lower yourself downward keeping your torso alignment the same the entire time.
-Be sure to keep your knees inline with your feet.
-Descend until your knees are at 90 degrees or a bit further where your thighs are parallel to the ground.
-Stop your descent via your leg muscles, and return upward to the starting position, keeping your back alignment the same.
Tips:
-Begin by going slowly so that you carve and learn the proper path of motion. The two most common mistakes are 1. Allowing the knees to move forward which eliminates usage of the butt muscles and 2. Allowing the torso to cave forward which decreases the range of motion that the legs work as well as causes the lower back muscles to erroneously assume load.
-Try holding your arms straight out in front of you like the Frankenstein Monster. Keeping the angle of your arms relative to your body constant, attempt to squat through a full range of motion keeping your arms parallel to the ground the entire time. If you accomplish each listed aspect, you will be correctly hip-hinging and using all of your leg muscles properly.
