I think that for the average person who wanted to big a bit bigger and stronger and who may not (at first) have a lot of understanding of exercise selection and placement, a program like SS would be idealI think too much choice early on coudl lead to people eliminating or substituting exercises neddlessly (I cartainly would have been guilty of this)
The problem though, is that most things (magazines, larger internet sites) readily visible to novices make programs like SS invisible or appear overly complicated.
Magazines prefer to sell the "look like QB Drew Brees" workout in a poster style format.
This confused me for a long time.
Complication makes it easy to explain failure.
