I absolutely agree. It doesn't get easier. You're just able to push yourself harder when training without having to worry as much about compromising recovery or overtraining. Still gotta use good form, good training programming, watch the macros, eat a house or two, sleep like a baby, etc.
Furthermore aas like var initially gives a huge strength boost meaning you end up lifting quite a bit more than you did last time even though your musculature hasn't really improved in a corresponding fashion-you're just temporarily stronger. That's a double edged sword, your training ends up inflicting more than normal stress on your muscles and your system has to work extra hard to make you recover.
