I haven't done conventional deadlifts more than a few times this summer but yesterday I wanted to know what working on my weak link (squats) had done for my conventional deadlift.
Basic workout schedule has been upper-off-lower-off.
Basically my leg workouts for the last couple of months has been a simple 2 month squat peaking program. =>Couple of sets of below parallel squats (began at Aug 14th - 70% 2x10, ended Oct 14th 110% 1x1) followed by couple of sets of heavy sldl's/rdl's in the 3-6 rep range. In addition I have done 1-2 sets of legpresses (down to 90 degrees making sure lower back didn't round) and calf presses. Progression went as planned without hiccups to a 160kg squat rep. After peaking program I've now done only squats on leg day for a couple of weeks. Alternating heavy/light. No other leg work at all. All leg workouts have been submaximal as before and focusing on form. No belt or other equipment used at any time.
I knew that my previous PR 200kg should be easy to beat as the last time I tried 200kg it went up without too much strain
Anyway yesterday I managed to pull first 210 and then 220 kg (484lbs) and this was after doing a front squat speed workout. I didn't use any belt or straps. Pull was smooth and felt great, lockout was easy so I enjoyed myself a while in lockout position.
I was tempted to add 7.5 kg to break the magical american round 500lbs number but decided to save it for a later time. Probably a session focusing on the attempt only.
I'm sure that my goal 500lbs DL before the end of this year will happen thanks to squats and sldl's/rdl's. My squat is still pretty low but it's good to know that improving it will help my other lifts in a big way.
