The squat is a compound exercise that utilizes the full body
during its execution. The main muscles targeted include the hamstrings, quads,
hips, buttocks, lower back and core. However, this exercise also strengthens
the bones, ligaments and insertions of the tendons throughout the lower body.
There are several ways to perform a squat and one can use
several different pieces of equipment to make it more challenging (dumbbells,
barbell, kettle-bell, etc). It is very important to note that one should never start
to load (use weights) a squat until one can perform an air squat with perfect
form. The reason for this is because the more load, the more likely one can get
injured.
It's amazing how often I come across a person who was not
taught the proper technique of the squat. So, I've decided to put it in
writing. I will describe a basic air squat. Firstly, your heels should be just
outside of hip width apart and your toes pointed outward (not quite 45°).
Your upper body should be in set position throughout the entire movement - to
get into set position, simply raise your shoulders up, pull them back, and set
them down. Throughout the entire movement, your weight should be in your heels.
The first part of your body to move is your hips. Bend your
hips far back as if you were going to sit down onto a chair. Your knees will
then follow. Make sure your knees bend in the same direction that your toes are
placed and never bend your knee past your toes. You can have your hands extended out in front of you for balance. Next, lower your buttocks down
to as low as your are comfortable without breaking your form. The ideal
position for your thighs would be below parallel with the floor (very deep
squat) - if this is too difficult, don't worry, you can work up to this. From
the bottom of the squat, push through the heels to move your body upwards and
return to starting position, squeezing your buttocks.
