Suppose I'll get in on this. Like critietaeta, I was in the other 600DL thread but why not join here. A 600 wrapped squat is one of my lifetime goals. 505/545 are my best squat/dead right now.
Tried training with sub-max, higher volume for a while and that didn't do anything for my 1RM. The plan is to experiment with reverse band stuff for a while. Squat and dead once per week: one week heavy squat and DL reps, next week heavy DL and squat reps.
I would like to get 515 w/o wraps by, say, August (or before jakerz, whichever comes first lol) and then work on pushing a wrapped squat above 545 by the end of the year. 495 being my best squat w/o wraps.
