Because 5x5 3 times a week is retarted. You won't progress after 3 weeks due to CNS burnout. Moreover, the triceps isolation is f***tarded because your bench and OHP are never gonna go up with them there. The planned progression is even more stupid and unrealistic. Max you can run it is 3 weeks.

Jason Blaha basically just took Stronglifts 5x5 and just cincai add in alot of isos and exercise. It's brainless shit. He gives good advice, but dunno why he made such a shit routine.
Yes, SS can be done by anybody actually. It's just the diet you need to suit yourself. If you fat eat at maintain, if skinny you may do a moderate bulk. Notice that SS doesn't have tricep iso.

With adequate rest and food intake, I think it's not really that retarded for a novice. Personally, much better than novice doing broplits.

I think it's a different outake than those strength focused programs.

"the program just isn’t specific to powerlifting. It was never intended to be specific to powerlifting. Blaha developed this program explicitly for bodybuilding.

In my opinion, the overall volume on this program is high enough that your intensity has to be lowered. As such, the bias is clearly towards hypertrophy… that was Blaha’s intent after all. As powerlifters, we want to emphasize strength and technique with a healthy dose of hypertrophy as a novice. It definitely isn’t our goal to emphasize getting bigger, though."

"Some of the valid criticisms of Starting Strength and StrongLifts 5×5 are that they don’t include enough direct arm work and upperbody volume for optimal hypertrophy. Well, that isn’t a problem on Blaha’s program."

Wrong person though. I've never suggested Starting Strength. I've never used it so I can't say more about it. ...
