I'd like to congratulate my clients Tom and Pete the Fireman on some heavy trap bar deadlifts this past Monday.
Tom pulled a 20-point PR of 555 pounds.
Pete pulled 505 pounds, which is his first 500+ deadlift, and is also well clear of 3x his bodyweight of around 160. Last time he tried to pull a new PR he got 455 but couldn't even move 475.
As if they need it, I just sent them the link to this article by Mike Robertson. It's got five useful tips for deadlifting.
