This is a 405 lb single arm deadlift I did a few years ago. The bar has two fat rubber 45 lb bumper plates and two iron 45s on each side. I was using a Dominator Athletics Lifting strap for this. There have been a lot of people commenting on my grip strength in this video. While I do have extremely strong hands, this lift did not require an extremely strong grip. I don't recommend doing this type of lift unless you are a very seasoned lifter or are under the guidance of someone who knows what they are doing.
