haha sounds like what I went through with my former gym buddies. They wanted to do pyramids or sets to failure, with someone else grabbing the bar off for bench and pretty much rowing it on the last rep, random isolations and celebrity "routines".
I got them doing the PTC method with me for about 2 weeks before they were sick of "squatting too much".
I used to hate deadlift and bench due to being shit at them until I realised that the only way to get better was to do more of it.
You'll end up training alone if you want to do it effectively.
I don't really do warmups on anything apart from overhead press, though I sit and hold a glute to calve squat at bodyweight before squatting.
