Bend your knees. Don’t try to use your upper body to muscle the bar up. Work on bending your knees and bring your leg drive into the lift.Back as straight as possible. Ensure you push your chest out to straighten your back before lifting. A good tip is to get someone to film you from the side as you do a set so you can see how straight your back really is. A hyperextended or arched back is the way most deadlifting injuries occur, so be conscious of keeping a straight back.Explode through the ground! When you initially lift the bar, don’t think about pulling the bar up from the ground. Instead, think about pushing the ground away from you. This will help bring more leg drive into the movement and make it easier when lifting heavier weights.Lift speed. Make sure you lift and lower the back at the same speed. Apart from other gym-goers hating you for slamming the weights down, you’re also missing out on an important part of the lift by dropping it instead of lowering the bar back to the ground.
