Powerbuilding/powerbuilding lite on 3 days

Hi, I've been training for a few months now a full body routine 3 day/week which worked well and im still making gains. But it's starting to get Hi, I've been training for a few months now with a full-body routine 3 days a week, which has worked well, and I'm still making gains. But it's starting to get really boring, in spite of small volume/intensity variations undulating across the week.

I'd like to try the Powerbuilding Lite, but I'm really constrained to 3 days a week. Any recommendations, or advice against it, if I wanted to bump up the volume to match the program volume while still running it on 3 days instead of four?

Perhaps the original Powerbuilding program on 3 days could be the solution—maybe stripped of some accessory work?

Thanks in advance.
