If you’re a beginner I’d say you’d probably survive the program. If you’re a beginner, I’d just stick w/ 5x5. As you advance drop it to 3x5 and eventually 2x5.
However, if you’ve been powerlifting for a while, I’d suggest a different style of program.
I’d suggest staying away from the 5x1 intensity days. Keep it the same 5x5 for a few weeks. If you get to a point at week 4 or 5 where you wanna have a heavy weight in your hands, go ahead and work up to a heavy single that week for each lift - not a max single, but a heavy single. Then go right back to the 5x5.
Just take your time. Build don’t test.
