In the snatch, the lifter lifts the bar as high as possible and pulls themselves under it in a squat position, receiving the bar overhead with the arms straight, decreasing the necessary height of the bar, therefore increasing the amount of weight that the lifter may successfully lift.
Back squat
The back squat is where you have the barbell positioned on your back or on your traps to be accurate. You then proceed to squat down to below paralell (hip crease below knee) and stand back up.
