Nah when you cut you gotta reduce volume. You lose damn near all your capacity to recover. I forget what site said it but they recommended cutting up to 2/3 of your volume in a hard (- >500kcal/day) cut. PHAT is like the opposite of a cutting routine, you would die.No lifting routine is inherently bad for cutting, routines with burnouts while you're in a caloric deficit will be taxing tho
The reason pure strength routines are often recommended is because they usually spare muscle the best, but depending on where you are at fitness-wise any routine will work as long as you are in some sort of caloric deficit
I remember my first cut I started losing strength, so I tried to up the volume... shyt was Strength plummeted, I think my immune system tanked too. It was the worst cut ever.
So if SS is less volume than what dude was doing I would go that route. Still though, squats or deads every trip?
