first, no i don't have practical programming yet, only SS.

Rip discusses the various assistance exercizes that are useful once linear progression on the primary lifts stall out sufficiently.

He includes tricep extensions and standing barbell curls in there, however reluctantly. At what point do these types of exercizes become necessary? It seems like the advanced novice program stops with Dips, Back Extensions, Chins, and Situps.

I get that curls and extensions are much less useful than chins and dips, which are less useful than squat, bench press, overhead press, and the deadlift. However, he wouldn't have put them in there if they weren't useful in some circumstances or at some point in training.

thoughts? i am going to buy practical programming at some point... i'm just fucking broke right now, so bear with me.
