So I’m pretty new to the gym and on my second week of GZCLP. I’m curious what the reasoning is for no AMRAP set in the tier 2 exercises. I was under the impression muscles grow more when pushed close to failure, so why wouldn’t you want to do that in the low weight/high rep sets?

Also on a slightly related note: can I do the tiers out of order? If for example the squat rack is taken, can I do my tier 2 bench press first and my tier 1 squats afterwards or is that not recommended for some reason?
