Read the sticky on camera position for the deadlift. Follow the deadlift setup steps. Bar is swinging away from shins so assume you're not lining up over mid-foot. You're not setting you chest. Try not to release your grip during the set. When the weight returns to the floor reset your back, get tight and pull. Think about pushing the floor away. Focus on holding your back angle. Keep the back tight with shoulders and hips rising together.
