Look at the best deadlifter’s in the world and you’ll find a variety of different setups and techniques.
There is no one BEST deadlift technique.
There are even two completely different ways to deadlift: sumo and conventional.
You can breakdown those two styles even more: flat/round back, hip height, wide/moderate/narrow stance, head/hand/foot position, grip etc.
Even with all the varying styles, there are three rules almost any great deadlifter follows.
Skim your body with the bar
Bar path is extremely important.
Look at any great deadlifter and you’ll notice that the bar is skimming their body the entire time (or they’re trying to).
