It's been a while since I've posted a Deadlift video. I'm hoping you guys could take a look and advise please?
(120kg @ 68.5kg).
Thanks!
Don't often post in here so someone feel free to correct me if i'm wrong but a few things are looking off here:
Your hips look to be too low. Is this the position you naturally feel strong at initiating the pull at? I ask this because your hips are so low your knees are having to travel so far forwards for you to get in position holding the bar. This in turn is causing you to initiate the pull with the bar almost over your toes as your knees will feel like they are in the way of the bar on the way up. You will not be able to generate a decent amount of drive at the bottom of the movement and take the weight of the bar if you start from that position.
Having your hips start at a higher position should allow you to bring the bar nearer to the middle of your foot and help you keep tension throughout your whole body.
I think its already been mentioned elsewhere but it might be a good idea to ditch the trainers or at least use trainers with a thin & flat sole, this is something that is contributing to having your knees so far forward as soles are generally thicker at the heel. I don't use full size plates when i'm deadlifting(the 20s in pure gym determine my bar height), so if you wanted to keep the same range of motion after ditching your shoes you could always do the same. Alternatively you would bring the bars starting position an additional inch higher off the ground if you kept with the same plate size and ditched your shoes.
Whats also been mentioned is using gloves, get rid of them and use chalk if required, this should improve your grip strength somewhat. A single liquid chalk bottle will last you around a year if you use it sparingly(and you only need to use it sparingly).
As for using mixed grip, i use it and have no issues but I alternate the dominant hand and I have no issues with asymmetry. Using straps is also fine so see what you prefer.
