I was taught what 172_driver describes, but have come to realise that aileron and backpressure goes together in a synchronized movement, i.e. not aileron first and back pressure when correct bank angle is achieved.
A smoth increase from no back pressure to the nessecary back pressure during roll gives you a nice and smoth turn. Use the same smoth back pressure release movement when you roll out of the turn.
The thing I try to point out is that it's not a step1, step 2, step 3 etc.
And yes, I'm not an instructor, just a 60 hours post-ppl that learned this after my skills test
