I agree with the others, too much volume on the Squats before the Deadlifts is probably not the best idea. Save yourself for the main work.
But, In the Beyond book, in the chapter called “2 Day / Week, New Template”, Jim lists “easier” Squat sets before the Deadlift 5/3/1 work.
It’s NOT (not, not, not) the FSL you were looking for but perhaps if you like to Squat before Deadlift then you may give those percents/reps a try.
The goal is to do every main lift twice a week. That would be light and heavy workouts. I think, FSL is more appropriate for Strength and Technique development than BBB.
I have seen several times on this forum people using alternate lifts with FSL, so I thought it wouldn’t really hurt. I do much better if I squat twice a week. I noticed that after removing BBB from my program and just doing the main lifts. In a few weeks my squat significantly dropped. All the other lifts were fine, though.
After adding Squat FSL 5x5 to my Deadlift day I was able to set a new PR and the weight didn’t feel as heavy anymore. My thinking is that medium volume at slightly higher intensity does the trick. BBB works as well, but my goal if not hypertrophy. I need more work on technique and ability to feel the lift (the muscles that are working).
Actually, now when I did reread your comment I suggest that move to the A/B style split and use 5s PRO + 3-5x5 as your leaders.
You dont have to listen me (I am not authority in the subject), but that is my favorite when I like to get semi frequent/easy volume for my lifts. It really does not matter, but that at least is recommended by Wendler.
Recently I came acros many threads that mention a setup similar to this one:
Deadlift 5/3/1 FSL
Squats 5 x 5 @ 80
Etc. There are many more.
I have no idea where these people got an idea of doing the main lift followed by supplemental lift @80 TM 5x5, but I like it much more than BBB 5x10 @50-60. The main reason are simple. I am an intermediate lifter who needs to work on his technique. Squating 2x a week would be ideal for practice and recovery. I used to squat 3 times a week when I was doing Starting Strength. One time a week is not sufficent frequency.
These people must have got that idea ftom somewhere, and I saw no opposition from Jim to it. If anyone could explain me the difference between supplementary lift @80% TM 5x5 and FSL 5x5 I would appreciate it. For now, the inly difference that I see is that FSL will be increasing from 65-75%.
I would gladly do 80%, just not sure which template this came from.
I don’t think the 5x5 @ 80% has been recommended much, as in yeah it probably works, but I think other methods are preferred over it. If you really bump it up to 80% and try to do the BBB thing with it, scale the main lifts to 5’s progression so you the supplemental doesn’t turn to grinders. Do a couple cycles like this for the leader, then swap the 5x5 for FSL and go for PR sets in an anchor. But really, I don’t think this would be a good idea, I get that you want to squat more often, but I think there are better ways, more widely used successfully.
What I’d recommend way more than that, as random internet guy advice:
-Full body template from either book (squat 3 times a week, much more sensible layout)
-1000% awesome templates from Jim’s forum, or the new book (more frequent heavy squatting but intelligently designed).
Yes, I completely agree that squatting @ 80% TM after Deadlifting is going to be pretty demanding. I tried just one set a few days ago, and concluded that it will certainly be wiser not to. However, in the way the lifts are spread out in 1000% awesome template, it seems to be pretty manageable.
Which new book are you talking about? I only have the original 5/3/1 and beyond.
