Like a lot of stuff Louie says, the details are kind of murky.
In an old article (Bench 500 Easy) he mentions doing illegal-wide grip benches. Build up your 6, 8, or 10 rep max. In a podcast( Westside Barbell Podcast: ME/DE for Upper Body) he talks about doing the wide grip benches for 6 x6. Push up the weight you do all 36 reps with. When you can’t progress anymore, drop back down (maybe to where you started) and do 8 x8. When you can’t progress, drop back down and try 10 x10.
That could go for 2 weeks, or like 2 months, depending on how you planned/worked it.
This guy is a serious lifter. I think he recommends 2 week “Lactic Acid” (add sets instead of weight) waves for squatting.
Louie is crazy. Sometimes you’re supposed to follow some chart exactly. Other times, he says you have to be ready to try 100 things to find one good one. “Everybody has their own way, and your way is the best way.”
You may need to experiment a little. The only rule is Stop doing it if it doesn’t work. I like to try stuff for a 3 weeks wave. Then decide over the weekend wether to stick for 3 more or switch.
