You will need to, along with jumps and throws. They’re crucial. And they have an impact on the weights. The lifting is only 1/3 of 5/3/1.
I would stick with how Jim has laid out 5/3/1 for a first time running it. That way, I’d know what works and what doesn’t. If I started changing it before I even ran it one time, I’d have no idea if my failure was a result of the program or my tinkering with it.
After a few cycles, I’d give myself some leeway. That’s what I’m currently doing with Tactical Barbell.
