Thanks for all this info, your articles have really helped me with programming intelligently. I'm nearing the end of a self-constructed upper/lower split and I want to give the B4B program a shot but have a couple questions before hand.
First, the way the program is written calls for a dead-squat. Does this mean a trap-bar deadlift or a squat starting at the bottom position from the safety pins? If it's the former, would you recommend a back/front squat or sumo/traditional deadlift to someone without access to a trap-bar.
Since I use a home gym I was considering weighted pull-ups instead of the lat-pulldown - a reasonable substitute?
Lastly, a more theory based question. It seems one could substitute various exercises to renew the program after completion as long as they are in the same movement category (hinge/squat movement, horizontal press, explosive pull, vertical press, vertical pull). Is my understanding accurate here?
