And not a particularly safe/good one.
The deadlift is a pushing exercise, not a pulling one. You push up through the legs, and then at the "top" you push with your hips. Your legs need to start off at least at 90degrees, and push upwards with your legs, then as you've still got a kink in them near the "top" of the push you push through with your hips.
Take it slower, don't bounce, and aim for correct technique rather than big weights. IF you screw up your back you screw up your whole body.
