Madcow2 said:There are several issues. The first is discussed explicitly on my site: http://www.geocities.com/elitemadcow1/5x5_Program/Linear_5x5.htm
The second issue is that people flat out do far far far more benching than pulling or rowing or squatting. Meaning they come to the program having put in a lot of time on the bench and they have a harder time pushing that lift up simply because it's been trained so much more already and likely chest/pressing has been an overwhelming focus so workload for presses and chest is flat or decreased while squatting and pulling is increased. It's not only a pure workload issue, just people being a lot more used to benching a lot where almost no one is really pounding 15 sets of squats a week and 10 sets of rows (specificity facilitates the adaptation and you work specifically on several very effective movements, unfortunately people's previous training is drastically out of balance).
Third issue. People put in a true heavy 5RM (i.e. minimum warmup and volume beforehand) and that spreadsheet assumes you will equal it with 4 ramped sets beforehand by week 4. For most people this isn't an issue. For every lift besides the bench, this hasn't been an issue. But for bench - it comes up because people like to put an absolute best case scenario number there.
Forth issue, combined with all the rest most people are still trying to make 5lbs jumps in Bench PRs every week rather than use the right percents. That just doesn't work all that well when you take all the other factors above into account.
This is stuff I probably need to address (I've already handled the weight loss/cut). If people get stuck early on a lift it's always the bench, never ever, even once have I seen an instance where it's anything else. This is the fault of current culture rather than programming.
I actually understand why people "miss" on the 5x5 better now. The absolute best 5rm is probably the highest they have ever hit. Good point.
What happens when we do miss it? Do you we need to revamp our numbers? Just wondering.
