adjusting 4 day program

I work as a fireman 24 hrs on then 48 hours off.  I have started back with sheiko using the intermediate small load prep on the app just to get in the groove.  I qualify for CMS, was wondering if any one has taken the 4 day a week and run it over 3 days? I like having at least a day in between training days but with my work schedule to train every other day.  I find i get much better results with at least a day in between.

If you're training day off/day on you could probably get away with running the program that way as well. The weekly structures are mostly there for easier planning I think but as long as you calculated the correct amount of time to your comp or max test day it should be fine.

Otherwise you'd be looking at fitting volume from the 4 days into 3 sessions which is doable but complicated if you have lots of different variations to deal with.

Another option, which works well for me, and would work well with your job schedule, is simply to run the 4 day program over 8 days instead of 7, or, in other words, just lifting every other day.  The only drawback is of course that it takes a little longer to complete the program.

But, I'm "old" (50), and need the extra recovery time anyway, so you may not like this solution.
