I've read a lot lately about Daily Undulating Periodization and it seems like an interesting concept. How would you combine this with 5-3-1 if at all possible?
I was thinking something like a 8 day week training every other day with the following programming.
DB Rows 3x8-10
Weighted Chins 3x8-10
Workout C has same lifts as workout A and Workout D has same lifts as B. They are performed for 5x10 @ 50% TM for first week, second week 4x10 @ 60%TM and third week for 3x10 @ 70%.
So overall intensity goes up during the mesocycle and volume goes down.
