Haven't seen or purchased the new version yet. I know in the article he said you add in singles, but what percentages are the singles after the scheduled 5/3/1 week? I also know he recommends doing the 3 rep week, then 5 rep week, the 5/3/1 week and then deload. What other changes/tweaks were there?
You do 2 singles after the last set on the 3 week and 1 week. You don't go for AMRAP on the last set of the main lifts either, on any of the weeks. I believe the singles are supposed to be at around 90%, and you're not supposed to ever miss those singles either. So, don't go for any crazy numbers that you're not sure you'll be able to get.
Is the 5/3/1 for powerlifting book actually available for sale yet? I've been keeping my eye out for it on EFTS, and I still can't find it.
I'd don't think so. Jim mentioned in his log that it was done and in editing a while ago, but I haven't seen anything since then.
