i agree with Grim's point.
i used to DL twice or even three times a week.... i could never do that now.
once i hit 315 or so, i couldnt do this at all.
I also agree with BTB. I squat 3-4(occasionally more) times a week. I can do this with no problem, but i cant DL more than once a week. If i DL once my back is ****ed up and it messes with my squatting. therefore i only DL once every two weeks real heavy.
I would DL one week and rack pull the next like you said. another thing i'm trying now (just started) is using band. I think sense it gets rid of the weight at the bottom it makes it less taxign.... not sure if true, but going to try it out.
basically if your assistance work and squats go up, your DL will tag along IMO
I <3 front squats
