How to Squat:
1) Stand straight, feet should be shoulder length apart.
2) Keep your back as straight as you can and go straight down until your butt is resting on the heals of your feet.
3) Keep your feet flat to the ground.
4) You must be able to comfortably maintain this position for 10-15 minutes.
