I have spent the last 2 days icing a godamn bakers cyst (bulge of synovial fluid coming out the back of my left knee) from squatting on Thursday almost a week ago. I am wearing a damn brace walking around. But I will still squat again this coming weekend. Also I think my video of me squatting 355 6 weeks ago shows I am capable or at least close to being able to squat 405. However I decided to drop back down in weight and work on training for a bit before going heavy again. I do not wish to blow out my knee. I have also been doing stiff leg deadlifts working the hamstrings twice a week again training to prepare for heavy squats again. But I do not just try and max out every week.
This is from mid december
I have not even attempted to go heavy again as I have been working on depth since everyone was just going to complain about my depth anyway and not give me proper credit when I squatted 405 so what is the point? If you don't think I am going to bury 405 I don't know what to tell you. My legs are getting stronger every damn week. I could 90 405 this week but everyone would just complain so I am burying lighter weights training instead. If I don't blow out my knee I will add actual inches to my quads by summer. So yeah just going to keep training like I said I am very happy with my squatting right now it is going great. If I wanted to do an all out max yeah I would hit 405 but that is showing strength not gaining right now I am focused on training and gaining.
I have every confidence you can squat 405 for a rep. I would strongly advise that you walk away from this nonsensical back and forth and temptation to do so. Reason being so that you can continue to actually walk. Stay lighter and add reps. Also, I'd consider replacing the squat entirely with a narrow stance, toes pointed ever so slightly out, feet low on the platform hack squats. These cause me zero discomfort in the back, knees, hips, etc. They are also in my opinion/experience the best weapon for improving quad sweep. Which at this stage of the game is where you need the work.
