So, 4 months ago I pulled 405lbs x3 and my 1RM was 415lbs. Over the course of the summer, I managed to squeeze my 1RM up to 430lbs, but that was several weeks ago, and I can barely manage to get 405lbs off the ground now. I feel that I've hit a plateau, I hate it. One thing which may be a part of this, is that I've slacked large on squats this summer. Barely squatting at all, and when I did it was light. Could this be impacting my deadlifts? Other than that though, I've made great gains this summer in everything else, I've put on 10lbs of lean muscle in the last 4 months and all my other lifts have gone up nicely. Help on breaking through this period of flaming deadlift ry.
