My deadlift hasn't went up in over a year despite squat and bench both going up considerably. I've gotten better at rep work but anything over 80% is still poor. 1RM is only about 430 for conventional, and 495 sumo.
Does it look like my upper back is too straight and I'm losing leverage because of it? Are my hips shooting up too much? I never miss weights at lockout and I'm weak off the floor, but my deficit pulls ironically feel stronger.
