The deadlift is not a squat movement, but without practice, most people end up squatting down awkwardly. Coach Marshall Roy, owner of RISE Gym in Philadelphia, has this tip to rethink the way you approach deadlifts: They're really about going back and forth, rather than up and down. Image by deb roby.

When inexperienced lifters try to deadlift, their knees get in the way as they lower the barbell. This is because they try to bend at their waist, rather than push their hips back. We've gone over the proper way to do deadlifts before, but Roy reminds you that the barbell's descent starts by shifting your hips back behind you, the so-called hip hinge. This way the bar itself clears your knees and can move in a vertically straight line.
To put it another way, the bar itself should never be the one to give way to your body. Rather, you need to move your body, by hinging back, out of the barbell's way.
