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?
Tier 2 sets are there to build volume and practice for those lifts - more reps at a lighter weight. I think you can definitely make your last Tier 2 set AMRAP as long as you can still finish the accessories. The order of exercises doesn’t really matter, personally I would try to do the Tier 1 sets first so you can get your maximum effort on those heavy sets, but the main thing is to complete all the sets
