Solid foundation of a strong deadlift there! Few little tips for further improvement 1. Tuck your chin, this will prevent you pulling with your head/neck, keeps the spine aligned throughout the lift and encourages engaging your legs to begin the lift (think heels through the floor) 2. At the top part of the deadlift, rather than leaning back, stand with good posture and pull the shoulders blades back, squeezing your back together (traps) and pushing the best out, this will prevent any unnecessary stress being placed on the lower back 3. At the beginning of each rep take your time to reset your start position, your doing a great job taking slack out the bar, resetting at the bottom ensures we start with proper form and prevents injury, it can also give your grip a much needed rest 4. Start with a nice gap between your shins and the bar to set up then bring the bar into you to where it's touching your shins before beginning the lift, this take a little extra mobility and lowered hips but ensures weight is distributed to our heels and we are working our posterior chains muscles (pulling muscles) and have great stability throughout. Great lift though and look forward to seeing your progression, keep it up!
