I’m not really sold on dynamic exercises for beginning lifters. They just don’t have the strength to move a meaningful weight with any sort of speed.
One thing I really like about the Westside for Skinny Bastards template is that it has a huge amount of emphasis on upper back thickness and lat development. Beginning lifters just don’t have lats or any sort of traps or rhomboids. Doing reps of face pulls, chins, lat pulldowns, rows, dumbbell flies, etc. twice a week are things absent in a lot of programs and are definitely necessary for the underweight guys to give them a more stable platform for benching, squatting and deadlifting.
I think if you took out all the board pressing and the chains and band exercises, you’re still looking at a great template. I think it’s silly that he has those things in there, since really skinny bastards aren’t really gonna have access to or be able to use 120 lbs of chains around an oly bar. Floor presses are a good substitute for board presses though.
