At the start of the Deadlift or in any pull from the floor you will recruit the Quadriceps muscle(top of the thigh) initially which gives us knee extension, the hip extensors are in isometric contraction,(not moving just stabilising) until the bar passes the knees when the hip extensors take over. What does this mean in real terms? When you go to lift you will be pushing back your knees and the bar should be coming up off the floor, with you keeping your chest at the same angle from start, if you get it wrong then all that happens is that your hip will rise as the knees move back and your chest will fall slightly. The weight is then pulled with the hip and with a large unnecessary load on the back to stay in contraction. This will be more prevalent next week when will be taking the bar from the floor in a full power snatch but try to get a feel for it as you pick up the bar today or any day for that matter.
