Everyone seems to skip leg day, not me!!! Leg day is by far my favorite, especially back squats (I can back squat 365lbs ladies ). While the back squat is a simple movement, it requires tremendous power in your legs. To perform a back squat you must place the bar on the back of your shoulders, lower your hips down bellow parallel and bounce out of the bottom of the squat . Once you bounce you will reach a spot in the lift where you will have to push down on the ground in order to push yourself and the bar up. The back squat involves a lot of momentum and a very big impulse. The impulse occurs during the bounce at the bottom and without a large enough impulse you will fail the lift. Don't skip leg homies, leg day is the best day.
