i squat 230x5 a little below parallel and i'm still putting on more weight every time. but my deadlift is horrible in comparison. i sumo deadlifted 225x5 a week ago and that was supremely difficult lol (i have to sumo deadlift because of an injury in my knee that prevents me from conventional). 225x5 is probably my max. what do you think is the limiting factor here, the muscle that is weakest that is preventing my deadlift from going up? i notice i have the most trouble when i'm initially trying to lift the bar up the ground (glutes maybe?) thanks guys.
